“Cognitive Dysfunction in Parkinson’s” – Dr. Marsh presentation

Geriatric psychiatrist Laura Marsh, MD, gave a wonderful presentation at last
week’s APDA/NPF Young Onset Parkinson’s Conference on the topic of cognitive
dysfunction in Parkinson’s Disease.  The presentation is likely of interest
to those in our Lewy Body Dementia group as well.

Dr. Marsh reviews the prevalence, pathophysiology, clinical characteristics,
and treatment of cognitive dysfunction in PD. She also describes much of the
research into cognitive issues and PD. (Dr. Marsh is the author of much of the
research!)

The conference was recorded.  You can find the video/audio recording here:

I hope you enjoy the presentation as much as I did!

No strong environmental risk factors for PSP

This French study looked at 79 cases with a clinical diagnosis of PSP, and 79 controls who were relatives. They analyzed “demographic characteristics, occupation history, diet habits, anti-inflammatory drugs use, alcohol consumption, smoking habits, gardening and leisure activities, and exposure to pesticides.” They found no “strong environmental risk factors for PSP.”

According to the article, “only four case-control studies on risk factors of PSP” have been published. Dr. Golbe talked about these in his webinar on PSP and CBD several months ago.

The authors argue that: “These data also suggest that PSP and PD have no major risk factor in common. Similar conclusions can be drawn from studies about multiple system atrophy.”

You may note that the French used the “Golbe criteria” to diagnose PSP. I’d have to look this up again but I assume it’s those over 40, with a history of falls, cognitive issues, and supranuclear gaze palsy. (The citation is: Golbe LI. Progressive supranuclear palsy. In: Tolosa E, ed. Parkinson’s disease and movement disorders. 2nd edn. Baltimore: Williams & Wilkins, 1993:145­61.)

INSERM Unit 708, Hôpital de La Salpêtrière, Paris, France.

BACKGROUND: The risk factors of progressive supranuclear palsy (PSP), a rare but severe Parkinsonian syndrome, are poorly known.

OBJECTIVE: To study the risk factors of PSP in a case control study among French patients.

METHOD: The study was conducted between April 2000 and December 2003. Cases were in- or outpatients of five large hospitals and fulfilled the Golbe criteria. Controls were relatives of patients from the same hospitals, free of Parkinsonian syndrome and dementia, and matched to cases for age, gender and living area. Data on demographic characteristics, occupation history, diet habits, anti-inflammatory drugs use, alcohol consumption, smoking habits, gardening and leisure activities, and exposure to pesticides were collected through a face-to-face questionnaire. A conditional logistic regression was used to analyse matched data and estimate OR.

RESULTS: 79 cases and 79 controls were included. Only a few comparisons were significant. Cases reached a lower education attainment than controls (odds ratio (OR) = 2.6 (1.3 to 5.3), p = 0.01). Analysis of diet habits did not show any major difference although cases ate meat or poultry more frequently. Conversely, controls ate fruits more frequently than did cases. No association was found between PSP and occupation, use of pesticides, gardening, alcohol consumption, smoking habits and anti-inflammatory agent use.

CONCLUSION: In this case-control study, we did not find any strong environmental risk factors for PSP.

“Instead of Saying X, Trying Saying Y”

This is a nice article with a helpful chart on using techniques of validation and redirection to deal with memory loss, repetitive questions, delusions or aggressive behaviors, when speaking with those with dementia.

Instead of Saying X, Try Saying Y
Use Validation and Redirection to Manage Daily Challenges
by Susan London, LMSW, QDCP
care ADvantage, Fall 2009

Let’s face it: caring for an individual with Alzheimer’s disease isn’t always a walk in the park; in fact, it can be downright stressful. Between memory loss, repetitive questions, false thinking or aggressive behaviors, each day often brings new challenges.

As a caregiver, your understanding of the disease as well as your attitude about the illness can have a great impact on the way you manage day-to-day caregiving responsibilities. And just because this illness has taken over someone close to you, it doesn’t mean you should let it conquer you as well. So what do you do when your loved one blames you for something you didn’t do or becomes paranoid that you are plotting against him or her? How about when someone sees objects that aren’t there or says things that simply don’t
make any sense?

If your gut reaction is to try to orient the person back to reality, you’re not alone. Many caregivers spend endless hours trying to prove who they are, where they are and what they are doing, but to no avail. They believe if they would just show a wedding album or have other family members confirm information that the person with Alzheimer’s disease will catch on and it will “click” for them. Even though a caregiver’s heart is in the right place, these efforts are often fruitless. Their loved ones may continue to press the issue, and sometimes even get angry or hostile at the “evidence” presented to them.

Fortunately, there are ways to manage daily challenges in order to minimize a caregiver’s stressful feelings and improve the odds that an individual with dementia will respond positively.

One of the best approaches to use with people with dementia is Validation—a technique that confirms their right to feel a certain way and express their emotions regardless of the situation. The Validation theory, developed by Naomi Feil, suggests that an individual
could be revisiting past events or trying to solve unfinished business. This helps explain why some people feel the need to go to work years after they retire or pay off a debt from decades ago. By validating their experience, you are meeting them where they are and sending a message that you still accept them no matter what. Another powerful approach to utilize is redirection—a behavioral intervention that shifts the individual’s focus, by distracting the person or moving away from an undesired topic or behavior to something more pleasant. See the chart on the following pages for some role-playing ideas that tap basic validation and redirection techniques to handle some of the most difficult situations.

When
Your mother says, “I want to go home!”

Instead of Saying
“This is your home! Don’t you remember? You’ve only lived here for 30 years!”

Try Saying
“Of course you want to go home! Your house was the prettiest on the block. Why don’t you tell me about those tulips you planted in your front yard?”

Why?
Memory impairments and disorientation can cause people to forget where they are. When they want to go “home,” it really signals a desire for a sense of safety and familiarity. Bring mom “home” by reuniting her with her favorite memories of what home represents.

When
Your wife says, “Get away from me, you’re not my husband!”

Instead of Saying
“But I am your husband! Look at our matching wedding rings. You know, you really upset me when you don’t remember who I am.”

Try Saying
“You must love your husband very much. I can tell by the way you talk about him. Why don’t you tell me about your wedding day?”

Why?
Memory loss can cause individuals to forget even their closest loved ones. When your wife becomes agitated, respect her space,
validate the love she feels for her spouse, and allow her to talk about “him” while you are sitting right beside her. Even though she may
have forgotten you today, hearing her talk about you will demonstrate that you are still very close to her heart.

When
During meals, your father refuses to eat and says, “You’re trying to poison me.”

Instead of Saying
“That’s ridiculous! Why would I ever do such a thing? Eat your meal and stop making up crazy stories!”

Try Saying
“Dad, I understand if you are feeling afraid, but I want you to know that I would never let anything bad happen to you. You are safe with me. By the way, this meatloaf is delicious. I am having a big plate of it myself. Let’s have some together and you can tell me all about
the fishing trip.”

Why?
It is difficult, if not impossible, to rationalize with people with dementia. Instead of trying to orient Dad back to reality, instill a sense of safety, and demonstrate it by eating the same meal as him or taking a bite from his plate. Once you’ve established trust, you can quickly refocus him by shifting the conversation to something more pleasant, such as a fun day he had by the docks.

When
Your sister says, “You stole my money! Give it back!”

Instead of Saying
“I’m sick and tired of you accusing me every time you hide your money. You stuffed it in your drawer five minutes ago. I saw you do it, so stop blaming me.”

Try Saying
“Oh no, your money is missing? I can see why you’re upset. Well, don’t you worry because I am going to help you look for it.”

Why?
It is common for people with dementia to hide items and forget where they are moments later. Since it can be embarrassing to admit this, individuals sometimes accuse others to take the focus off themselves. Rather than trying to deflect blame, simply let your sister know that you understand how she feels and that you want to help her resolve the situation. Then walk her over to the drawer and ask her to open it. When your sister finds her money, allow her to take pride in finding it all by herself.

When
Your grandmother says, “I have to leave now. I need to pick up Jimmy from school.”

Instead of Saying
“Grandma, Jimmy is a grown man. He’s 60 years old. You’re not going anywhere.”

Try Saying
“Oh Grandma, you have always been such a loving mother to Jimmy. Why don’t you come with me to get a drink of water and tell me all about what you love to do with Jimmy after school?”

Why?
People with Alzheimer’s disease often live in the past by re-creating experiences that happened long ago. Despite the fact that Grandma hasn’t picked Jimmy up from school in decades, her maternal instinct is still very strong, and she feels an urgency to follow the same routine she did while he was growing up. Take this as an opportunity to reunite your grandmother with those happy memories: while you are distracting her from going to the front door, she will tell you all about those wonderful times she had with Jimmy and will forget all about wanting to leave.

When
Your uncle believes he’s still at work. He treats you like an employee and tells you he needs the paperwork finished by the end of the hour.

Instead of Saying
“Are you starting with that nonsense again? You retired in 1985. How many times do I have to keep reminding you?”

Try Saying
“You really run a tight ship around here! I guess that’s what makes you such a good boss. I’ll make sure to get the paperwork to you, but I could use a little help. Can you assist me with one of the documents?”

Why?
It is not uncommon for people with Alzheimer’s disease to strongly affiliate with important roles they have taken on in the past. The fact that your uncle thinks he’s at work suggests that a job is still very meaningful to him. Use this moment to create an activity that can contribute to a sense of purpose. Bring him a phone bill or other document and allow him to “help” you interpret it. Support his efforts and remind him what a great boss he has always been.

Concomitant PSP and MSA (4 Cases)

This recently-published article is about one case of concomitant PSP and MSA in the Queen Square Brain Bank in the UK. (That’s one out of 120 cases of path-confirmed PSP.) And the article mentions that there are three other (independent) cases. One of these three is a Mayo Jax case; it was one case out of 290 path-confirmed PSP cases. So, that answers the question as to whether this is even possible!

Here are the highlights:

* “The apparent rarity of cases of coexistent PSP and MSA initially suggests they might be due to mere coincidence, rather than the result of any biological overlap.”

* “Grading of PSP tau pathology provided a score of 6, consistent with moderately severe tau pathology typical of Richardson’s syndrome [29].” [Robin’s note: this indicates that the RS form of PSP has more severe tau pathology than the other common form, PSP-P.]

* “Nevertheless, taking into consideration the rarity of MSA and PSP, in addition to the small number of cases that come to autopsy, the findings of 4 cases reported to-date is higher than expected.”

* “Whether these cases represent a pre-clinical stage of MSA, or simply a biological coincidence is yet unknown. The occurrence of pre-symptomatic MSA should be confirmed in prospective studies in which detailed neurological evaluation has been performed in the final months of life.”

* “Clinically our patient fulfilled the NINDS-SPSP operational criteria for the diagnosis of probable PSP and the only feature that might have suggested MSA was the urinary incontinence which started 20 years before death and resolved. The lack of overt cerebellar features of MSA is consistent with mild olivo-ponto-cerebellar pathology, whereas the prevailing parkinsonian syndrome is in line with more severe striato-nigral-degeneration, or the baseline PSP pathology.”

* “The rarity of pathologically proven cases of combined PSP and MSA does not provide sufficient evidence to confirm a common pathogenic mechanism for both diseases, but our findings suggest that systematic screening for PSP and MSA changes in atypical parkinsonian patients and control brain bank donors is warranted.”

Concomitant progressive supranuclear palsy and multiple system atrophy: More than a simple twist of fate?

Silveira-Moriyama L, González AM, O’Sullivan S, Williams DR, Massey L, Parkkinen L, Ahmed Z, de Silva R, Chacón JR, Revesz T, Lees AJ, Holton JL.
Reta Lila Weston Institute for Neurological Studies, UCL Institute of Neurology, London, UK.

Progressive supranuclear palsy (PSP) and multiple system atrophy (MSA) are both rare neurodegenerative diseases.

In the Queen Square Brain Bank, from 2001 to 2008, we received 120 cases of pathologically confirmed PSP and 36 of MSA, and one had concomitant PSP and MSA pathology.

The clinical symptoms in this case were compatible with PSP and did not predict the dual pathology.

The growing number of collective case reports, including the one reported here, might suggest an increased prevalence of concomitant PSP and MSA than what would be expected by chance.

Concommitant PSP and MSA (4 cases worldwide)

This recently-published paper addresses the question of whether PSP and MSA can co-exist.  The answer is “yes” but it’s quite rare.

There is one case of concomitant PSP and MSA in the Queen Square Brain Bank in the UK.  (That’s one out of 120 cases of path-confirmed PSP.)  And the article mentions that there are three other (independent) cases.  One of these three is a Mayo Jax case; it was one case out of 290 path-confirmed PSP cases.  So, that answers the question as to whether this is even possible!

Here are the most interesting excerpts:

“The apparent rarity of cases of coexistent PSP and MSA initially suggests they might be due to mere coincidence, rather than the result of any biological overlap.”

“Grading of PSP tau pathology provided a score of 6, consistent with moderately severe tau pathology typical of Richardson’s syndrome [29].”  [Robin’s note:  this indicates that the RS form of PSP has more severe tau pathology than the other common form, PSP-P.]

“Nevertheless, taking into consideration the rarity of MSA and PSP, in addition to the small number of cases that come to autopsy, the findings of 4 cases reported to-date is higher than expected.”

“Whether these cases represent a pre-clinical stage of MSA, or simply a biological coincidence is yet unknown. The occurrence of pre-symptomatic MSA should be confirmed in prospective studies in which detailed neurological evaluation has been performed in the final months of life.”

“Extreme Caregiving” for Someone with Behavioral Changes

This article on extreme caregiving appeared in a summer issue of Neurology Now magazine.  “Extreme caregiving” refers to caregiving for someone with behavioral changes.

The article mentions these two books on caregiving that sound worthwhile:

* “Elder Rage, or Take My Father Please! How to Survive Caring for Aging Parents,” Jacqueline Marcell, 2001.  (I suggest you check out Jacqueline Marcell’s website elderrage.com.)

* “The Emotional Survival Guide for Caregivers,” Barry J. Jacobs, Psy. D., 2006

The article includes a section called “Your Coping Toolbox.”  It is a handy list of things you should do to help your loved one and help yourself (caregiver).

Also, I liked the “MITIGATING AGITATION” section of this article.

There’s a short summary on the use of antipsychotics in treating dementia.

Definitely worth reading…

Caregiving
Who’s There?: When stroke or Alzheimer’s changes a person’s behavior, caregiving can become extreme. Here, experienced caregivers, patients, and experts share their stories and advice.
Neurology Now, Volume 5(4), July/August 2009, p 26-29
by Stephanie Stephens

Hands gripping her throat, Jacqueline Marcell’s elderly father, Jake, raged at his caregiver daughter for switching on a television movie channel he didn’t remember ordering. She finally broke free and frantically dialed 911.

After the incident, police took Jake to a psychiatric hospital, where he morphed back into a teddy bear. Eventually he returned to his chaotic, homebound life, struggling but failing to care for his elderly wife, Mariel. And Marcell was left once again to pick up the pieces for a father whose behavior was frequently and intensely out of control.

Both her parents had been diagnosed with Alzheimer’s disease, says Marcell, though not soon enough. She’s since become a passionate and refreshingly humorous advocate for caregivers, through speaking engagements and as the author of Elder Rage, or Take My Father Please! How to Survive Caring for Aging Parents (Impressive Press, 2nd edition, 2001). She’s on a mission to assure caregivers they have company-plenty of it-and counsels them to take care of themselves lest stress take its toll.

I was undergoing the most incredible stress of my life and catching every cold and sore throat possible. I felt like my immune system wasn’t working as well as it should. Later, I was diagnosed with invasive breast cancer and underwent six surgeries. Was the fact that I wasn’t taking care of myself directly related to my breast cancer? It’s my opinion that it was. (Studies done over the past 30 years of the relationship between psychological factors, including stress, and cancer risk have produced conflicting results. Stronger relationships have been found between psychological factors and cancer growth and spread than between psychological factors and cancer development.)

Your life and theirs comes apart, she says. You can’t trust them, a child in an adult’s body, and often they don’t trust you either.

Her father called her every name you can imagine. She wept consistently for a year. Still, Marcell reviewed her list of gratitudes daily-things for which she was grateful-and staunchly bore her emotional shield when confronting the worst moments. Her own struggle may be more extreme than what many of us will experience, but the wisdom she’s gained is universally applicable.

Every person who has ever lived has undergone the heartache of those who came before us getting old, getting sick, and passing away, she says. We understand it intellectually, but when it happens to our loved ones, no words can prepare us. We somehow think we’re the only one who’s ever experienced it.

Wendy Sessler understands, for she and her mother Mary Morgan have also walked this lonely but well-traveled road. Morgan, age 69, of Kill Devil Hills, NC, exhibited no apparent risk factors when she suffered a massive stroke in 1996. A clot in her brain stem affected everything, she says, resulting in behavioral changes.

It was like an alien had overtaken my body, says Morgan, who also cathartically authored her story, the book Like a Bolt (LAF Publishing, 2004). Lacking feeling on her left side, she uses a power wheelchair and walks maybe 10 feet if I hold on to something. I can’t keep my balance.

Unwelcome psychological changes have been no picnic. It’s pretty horrible, she asserts. She’s chronically depressed and knows why.

You wake up and half of your body’s turned to JELL-O.

Her devoted daughter, then 32 and happily married with three children, selflessly returned to help her irritable, frustrated, and frightened mother. She remembers Morgan needing things done right now! and using few words to say so, because it was easier.

When she made me upset, I reasoned that it wasn’t really ‘her.’ Taking care of her was just what I had to do, Sessler says.

A struck-down and fragmented Morgan says she didn’t mean to shout.

There was so much anger, yet I was in the background ‘listening’ with a detached feeling: mouth running, brain just going on, thinking I’d lost control of everything. A statement would come out of my mouth, and I’d think: ‘Where did that come from?’

Reacquainted with her pre-stroke identity eight years ago, she says, It was the first time I referred to myself as ‘Mary.’ I still look like her, have a lot of her parts, but I’m not her. Morgan knows many caregivers also struggle to identify their survivor as the person they once knew.

This condition is as new to the affected as it is to you. Understand their difficulties and know that loving them is something that you can’t overdo, Morgan says.

Cognitive dysfunctional changes in behavior are distressing and can be dangerous, whether caused by stroke or the progression of Alzheimer’s. Ignore them and they won’t go away.

FINDING HOPE TO COPE
If you don’t understand how to cope, you’ll flounder, Marcell says. Seek out the right doctors and the right medications for your loved one. Take it on like a project.

Remember too that the resulting behavioral changes are due to the disease or brain injury rather than the personality. Don’t take the changes personally, counsels Barry J. Jacobs, Psy. D., clinical psychologist, family therapist, and author of The Emotional Survival Guide for Caregivers (The Guilford Press, 2006). Caregivers can learn to stay cool when patients react to feeling threatened, misinterpret what’s happening, or become confused or agitated.

Still, managing paranoia, increased aggression, or psychosis can perplex and overwhelm even the most seasoned caregivers, including professionals. With Alzheimer’s, it’s essential to understand the progressive stages of the disease, says Dr. Jacobs. Healthcare professionals usually describe three broad categories (sometimes broken down into seven more detailed categories); ask yours to explain how they apply to the person you’re caring for.

In the early stages, the person comes to grips with the diagnosis and exhibits recent memory loss, often with depression or apathy. Caregiver supervision, including necessary reminders, may sustain precious patient independence.

Moderate/middle stage patients may be very frightened, agitated, confused with misperceptions, exhibit rambling speech, and get lost in familiar settings. Obvious emotional and behavioral problems are worsened by stress or change. Caregivers will want to provide orientation with predictable, secure routines that avoid over-stimulation.

In severe/late stages, the patient abandons self-care, is generally incapacitated with delirium or hallucinations, and becomes confused about past or present.

Then even the most devoted caregiver has a very hard time day in and day out, says Dr. Jacobs.

To lighten the load, he advocates locating resources like home health aides, support groups, and government services-locally or online-and emphasizes that knowledge is power when it comes to brain injuries such as stroke. Neurologists can delineate the stroke’s severity and location in the brain, along with how both factors affect memory, reasoning, vision, motor skills, and behavior. Neuropsychological testing can paint a clearer picture of current and future cognitive strengths and deficits.

You’ll have a pretty good idea of where they’re likely to be over time and what kind of compensatory strategy everyone must adopt, says Dr. Jacobs.

Temper flares are common, Dr. Jacobs says, but not every survivor becomes a brute. Instead, a patient may react slowly to stimuli, manifest little emotional expression, be seemingly unresponsive, or go from laughter to tears in seconds.

Marriages and partnerships may also be at risk, Dr. Jacobs notes. In fact, many simply don’t survive the tumult caused by stroke or other major neurological problems. In June 2009, The Journal of Clinical Nursing reported that after a stroke, sexual relationships were significantly affected, gender roles became blurred, and feelings like anger and frustration were confounded by a lack of independence and ongoing fatigue.

MITIGATING AGITATION
Agitation is a common behavior in people with dementia, and it can have a broad range of meanings, says Jason Karlawish, M.D., of the University of Pennsylvania Health System, Division of Geriatric Medicine, where he is Director of the Alzheimer’s Disease Center’s Education and Information Transfer Core and Associate Director of The Penn Memory Center. The patient wants to tell us something.

Often caused by fear, fatigue, or something bothersome in the environment, agitation may also be spurred by an unmet need. Medication might be required to quell it. In the event that the person manifests psychosis-loss of contact with reality-an antipsychotic may be prescribed. Antidepressants might be prescribed for depression or anxiety, and disinhibition-the inability to control impulses-may require mood stabilizers. (See box, Antipsychotics in Dementia Treatment.)

Beyond medication, though, caregivers can help reassure an agitated person and redirect or channel behavior in a new direction without flippantly minimizing the person’s suffering, says Dr. Karlawish.

Example: Don’t say, ‘Oh Mom, my memory’s not that good either.’ Acknowledge that it’s frightening and say, ‘I’m here for you even if you do have a memory problem. You still have a great smile and a sense of humor.’ Then move to another topic.

A physiological complaint may also prompt agitation, Dr. Karlawish says.

A parent who understands a child’s cry knows when it’s not a good one, and astute caregivers develop similar radar. Unmet medical needs can include infection, bowel impaction, or simply acute pain. Therefore, it’s critical to know when something’s different.

Unfulfilled psychosocial requirements such as boredom from sitting all day may be remedied by attendance at adult day care. However, a change in regular patient activities should still respect what’s already in place.

I always try to establish a predictable routine for patients-getting up and dressed, bathing, eating meals, says Martha Lentz, owner of Personal Health Care Solutions in Charlotte, NC. Lentz, a geriatric care manager, supervises clients with neurological conditions. Like others in this tight-knit caregiver community, she freely shares successful strategies.

When confusion or agitation set in, she calmly redirects client attention without being challenging. For instance, Lentz was falsely accused of being the girlfriend of a female client’s husband. The gerontologist reiterated that she was in fact a cousin and shifted gears by inquiring where the client had been lately. The response led to pleasant discussion of the client vacationing in Florida as a child with her parents, thus diffusing potential conflict.

An 18-year caregiver, Andrea Allen, also of Charlotte, avoids making strict demands of clients. Instead, she treads softly and makes suggestions.

Talk to them as though they’re a real person instead of someone with problems, she says. Don’t be so quick and definitely don’t force.

Marcell’s parents would ask certain questions over and over again. To deal with it, she wrote answers to these common questions on file cards. Then, she would ask her mom and dad the question before they did. It became a kind of cognitive exercise, a game that they actually enjoyed.

Since people with dementia may have difficulty determining the date and time, Marcell suggests that caregivers go with the flow and live in the reality of the loved one’s moment. When asking their age, know that they may be many ages in a day. Remove mirrors and instead surround them with photos of their past years.

Mary Morgan implores caregivers: Please don’t assume you know what the stroke survivor is thinking. Listen and pay attention. If the survivor says ‘that hurts,’ believe it.

She also advises keeping noise and distraction at a minimum, both of which put the survivor’s brain in the ‘blender mode’ and prevent focus on one task. Offer meals without too many confusing choices and present options singly: Do you want beef? Do you want chicken?

Watch for inklings of possible survivor self-harm. When you’re vibrant, the life of the party, and suddenly you don’t go to the party any more, it’s bad, Morgan says. You were once respected for your intelligence, and now nobody thinks you have any. Reassure the survivor that ‘You’re important to me’. I want you to be around.

Of course, for caregivers to still be around, they have to take care of themselves first, Marcell insists: If you go down, you can’t help, so be Number One. Take a walk or a hot bath. Get a massage. Know that if your loved one were totally cognizant, he or she wouldn’t want the child to have this much stress.”

Most important, touch and hug the survivor. It’s amazing how the whole body just lights up, Morgan says.

Antipsychotics in Dementia Treatment

* An increased risk of death has been reported in patients with dementia receiving antipsychotics. A three-year study led by Clive Ballard, M.D., of the Wolfson Center for Age-Related Diseases at Kings College in London, showed that only 30 percent of demented patients on antipsychotics were still alive at the end of 12 months, compared to 59 percent of those who took a placebo. Researchers found that the risk increases substantially after more than a year on the medications.

* The British study is not the first to recommend judicious use of antipsychotics among patients with dementia.

* Antipsychotics do have benefits for the psychotic patient who cannot be redirected, comments Dr. Karlawish. The decision to use them has to be based upon very careful understanding of whether known risks are worth the potential benefits of treatment. A clear, measurable goal should be set regarding benefits and if that goal is not achievable, the medication should be stopped.

* For Jacqueline Marcell, the risks were worth it. If doctors had not utilized these medications, she says, I could not possibly have controlled my father. If medication use shortens life, it is my opinion that the patient could also shorten others’ lives if not correctly managed.

* Dr. Karlawish cites FDA black box warnings noting increased risk of death and contra-indicating use of the drugs for control of agitation with Alzheimer’s dementia. Other potential problems, he says, include difficulty with walking, exacerbated risk of falls, increased risk of developing diabetes, and increased risk of death from cardiovascular disease.

Your Coping Toolbox

TO HELP THE PATIENT OR LOVED ONE:
* Believe it when that person says, It hurts.
* Redirect and diffuse aggression.
* Offer single choices of meals or other options. Don’t force.

Door Opens to Health Claims Tied to Agent Orange
By James Dao
New York Times

Under rules to be proposed this week, the Department of Veterans
Affairs plans to add Parkinson’s disease, ischemic heart disease and
hairy-cell leukemia to the growing list of illnesses presumed to have
been caused by Agent Orange, the toxic defoliant used widely in Vietnam.

The proposal will make it substantially easier for thousands of
veterans to claim that those ailments were the direct result of their
service in Vietnam, thereby smoothing the way for them to receive
monthly disability checks and health care services from the department.

The new policy will apply to some 2.1 million veterans who set foot
in Vietnam during the war, including those who came after the
military stopped using Agent Orange in 1970. It will not apply to
sailors on deep-water ships, though the department plans to study the
effects of Agent Orange on the Navy.

The shift underscores efforts by the secretary of veterans affairs,
Eric Shinseki, a retired Army chief of staff and a Vietnam veteran
himself, to reduce obstacles to sick or disabled veterans’ receiving
benefits. The department has come under sharp criticism from Congress
and veterans groups for long delays in processing disability claims.

“Since my confirmation as secretary, I’ve often asked why, 40 years
after Agent Orange was last used in Vietnam, we’re still trying to
determine the health consequences to our veterans who served in the
combat theater,” Mr. Shinseki said in a statement. “Veterans who
endure a host of health problems deserve timely decisions.”

The veterans department already recognizes more than a dozen
conditions as being presumptively connected to Agent Orange exposure
in Vietnam, including Hodgkin’s disease, prostate cancer and Type 2 diabetes.

But for diseases not on that list, veterans are required to provide
evidence directly relating their service in Vietnam to their illness,
a requirement that often leads to application rejections and prolonged appeals.

Veterans department officials estimate that about 200,000 veterans
might seek benefits under the proposed change in policy. But they
said they could not estimate the cost of the change until the policy
underwent public review and was published in final form, which could
take several months.

Mr. Shinseki’s decision is a victory for groups like Vietnam Veterans
of America, which has been pushing the department to add Parkinson’s
disease, ischemic heart conditions and hypertension to the list of
diseases presumptively linked to Agent Orange.

But the new policy is also likely to prompt debate over how much
responsibility the federal government should take in compensating and
caring for aging veterans who are exhibiting a growing list of
physical and psychological problems.

The most common of the three illnesses, ischemic heart disease,
restricts blood flow to the heart, causing irregular heartbeats and
deterioration of the heart muscle.

Parkinson’s disease is associated with a loss of cells that secrete
dopamine, a brain chemical essential for normal movement. Patients
develop tremors, rigid posture, impaired balance and an inability to
initiate movement.

Hairy-cell leukemia, a rarer condition, is a slow-growing cancer in
which the bone marrow produces too many infection-fighting cells,
lymphocytes, that crowd out healthy white blood cells, red blood
cells and platelets.

Agent Orange, named after the color-coded band on storage drums, was
the most common herbicide used in Vietnam to clear jungle canopy and
destroy crops. It contained one of the most toxic forms of dioxin,
which has since been linked to some cancers.

Aides said Mr. Shinseki’s decision was influenced by a report
released in July from the Institute of Medicine that found “limited
or suggestive evidence” of an association between exposure to
herbicides and an increased chance of Parkinson’s disease and
ischemic heart disease in Vietnam veterans. The report also found
“sufficient evidence,” a stronger category, of an association between
herbicides and hairy-cell leukemia.

The report, written by a 14-member panel appointed by the institute,
was based on a review of scientific literature. The institute is
required by Congress to monitor the health effects of herbicides used
in Vietnam and produce updates every two years.

In its report, the panel warned that there was a paucity of
epidemiological data about Vietnam veterans. As a result, the panel
said, its findings did not represent “a firm conclusion” about
herbicides and Parkinson’s and herbicides and ischemic heart disease.
It said it could not estimate the chances of veterans’ developing
either disease.

Despite those caveats, the Institute of Medicine report has been
cited by veterans advocates as providing sufficient evidence to
justify a rule change. Under laws governing Agent Orange policies for
veterans, the department cannot make benefits decisions based on
cost, only on the scientific evidence. Aides to Mr. Shinseki said the
Institute of Medicine report provided that evidence.

Some doctors and researchers say the expansion of Agent Orange
benefits has been based on weak or inconclusive science, given the
lack of studies on Vietnam veterans. Those skeptics argue that
diseases like prostate cancer or Type-2 diabetes are just as likely
the result of aging, lifestyle or genetic predisposition as exposure
to Agent Orange.

“Clinical outcomes” paper – full paper available

Earlier in the year we posted about the O’Sullivan “Clinical outcomes” paper on PSP and MSA.  This is one of the most important papers published to date on these two disorders.

The UK researchers analyze the clinical records (to determine clinical milestones and survival time) of 110 pathologically-confirmed PSP cases and 83 path-confirmed MSA cases (all from Queen Square Brain Bank).

This paper is now available online for free.  I’ve noticed that articles don’t always remain free, so if you want a copy I suggest you save it to your hard drive now.

Here’s a link to the article:

Dr. Hermanowicz (10/8) on PSP – Webinar Notes

Here’s my soapbox message today… I’m finding lots of things tedious about these CurePSP webinars. Two hours is too long, and the repeated info from Janet Edmunson and Kathy Speca is unnecessary. My “control panel” showed the attendee count varied between 160 and 190. Can’t CurePSP determine if a majority of these are repeat visitors, and skip the duplicate stuff? The Parkinson’s Disease Foundation had a great webinar last week that was one-hour long; that was perfect. The other thing that is a total waste of time is that the questions are read verbatim and with all the introductory comments. Can’t CurePSP skip this, and consolidate the questions?

And here are my comments about Dr. Hermanowicz’s presentation… I liked the fact that his message to spouse caregivers was so strong: spouse caregivers should not be caregiving 7×24. This is not a good situation for the caregiver. And I thought the format he used to describe PSP, CBD, and MSA was very effective. He seemed to be very up on the O’Sullivan and Williams research but I thought it was unfortunate that he didn’t take the opportunity to explain that there are two common forms of PSP — one with dementia and one without. Those dealing with the non-dementia form of PSP don’t appreciate hearing that a primary symptom of PSP is dementia.

Enough of my layperson opinions. What follows are the PSP-related and general notes I took from the webinar.

Background Info on Presenter – Dr. Neal Hermanowicz

He’s a Board certified neurologist with fellowship training in Movement Disorders at the Univ of Michigan. His mentors there were Drs. Anne Young, Sid Gilman, and the late Jack Penney.

Since 1999, he’s been at the University of California Irvine to establish a clinical program in Movement Disorders (in the Institute for Memory Impairments and Neurological Disorders). Clinical trials in treatment development for PD, dystonia, Huntington’s Disease and, soon, MSA.

Since 1999, he’s been the Medical Director for the Traub Center for Movement Disorders at the Eisenhower Medical Center in Rancho Mirage, CA.

He just attended the UCI atypical parkinsonism support group meeting on 10/7..

Presentation by Dr. Neal Hermanowicz
Topic: Fundamentals & Diagnosis of PSP, CBD, MSA, and Related Disorders

Three Disorders
===========

These three disorders have common features — slowness and stiffness of movement (Parkinsonism)
Similar ages of onset
Progressive (and gradual)
Unknown cause (which is not unusual in neurology)
Uncommon (so it’s hard for clinicians to make a diagnosis)
No specific treatment for the diseases

The diagnoses of these three disorders is established by clinical assessment, ie, history and physical examination.
No tests confirm the diagnosis.
There is always some level of uncertainty, even among experienced clinicians.

PSP
===

Patient #1 – PSP
68 year old man referred for possible PD. He has been falling recurrently and without warning for the past year and a half. Gravelly voice (noticed by wife). He coughs when eating and drinking. He is losing weight. He complains of vision problems. He acknowledges that he is slower in his movement and his neck feels stiff.

History of PSP: Dr. Richardson, in Toronto, saw a patient in 1955. He called the disease by the name “progressive supranuclear palsy.” Steele, Richardson, and Olszewski published on PSP in 1964. This 1964 included brain pathology. Seemed reminiscent of post-encephalitic parkinsonism.

PSP Background:
Prevalence is 1 to 6 in 100,000
Jankovic: of 100 PD patients he sees in his clinic, actually 5 have PSP [Robin’s note: not sure I got that right]
Symptom onset average age 63.5
Diagnosis average age 66.5
More men than women affected at a ratio of around 2:1. (We don’t know why. This is similar to PD.)
Rarely runs in families

PSP Initial Symptoms:
Unsteady gait or falls: unpredictable falls
Speech difficulty
Cognitive/behavioral change
Vision problems
Slowness
Clumsiness
Swallowing difficulty

[Robin’s note: the initial symptoms for Richardson’s Syndrome are very different from PSP-Parkinsonism. This is well-explained in the O’Sullivan et al 2008 paper and several Williams papers.]

PSP Diagnosis: consolidated several criteria here, including the SPSP-NINDS criteria
Onset 40 or older, and gradually progressive
Impaired balance and falls in the first year
Eye movement abnormalities (difficulty looking downward or side to side is characteristic of PSP)
Early speech and swallowing difficulty
Symmetric (both right and left side of body) slowness and stiffness
Cognitive impairment (different from the type we see in Alzheimer’s)

Difficulty looking upward is very common, even in normal aging

PD is asymmetric

PSP Pathology: described by Richardson; brain cell loss in characteristic areas; neurofibrillary tangles within brain cells (tau); locations correlate to symptoms and exam

PSP Cause:
The cause is unknown. Research on environmental and genetic factors is currently underway, enrolling at 10 sites within the US. This is not a treatment study but a gathering-of-information study.

PSP Prognosis: (according to O’Sullivan et al 2008)
Measure of time from onset to milestones:
* Frequent falls: 3.9 +/- 2.5 years
* Wheelchair: 6.4 +/- 2.7 years
* Severe swallowing difficulties: 6.4 +/- 2.4 years
* Disease duration: 8.0 +/- 4.1 years
These are averages, statistics. More severely impaired people may be seen at these centers that were part of the study.
Progression rate is variable from one person to another.

[Robin’s note: The O’Sullivan et al 2008 article is titled “Clinical outcomes of progressive supranuclear palsy and multiple system atrophy.” This article is available for free online here
http://brain.oxfordjournals.org/cgi/con … 131/5/1362 ]

PSP Treatment: (from Burn & Warren 2005)
Nothing specific for the disease process itself
Involuntary eyelid closure (blepharospasm or apraxia of eyelid opening) can be treated with botulinum toxin injections
Double vision can be treated with prisms in eyeglass lenses
Dry eyes can be treated with artificial tears
Speech and swallow problems should be evaluated by a speech pathologist
Excessive saliva can be treated with atropine drops or botulinum toxin injections into salivary glands

PSP Treatment:
Cognitive symptoms treatment is under investigation. Mixed reports on Aricept (donepezil). Exelon (rivastigmine) is being looked at and is potentially beneficial. He tends not to use Alzheimer’s medications.
Mobility/fall risk reduction through physical therapy.
PD medications such as levodopa and amantadine are reasonable to try in PSP. These medications have the potential for unpleasant side effects.
Brain surgery: not yet beneficial; under investigation
Education
Support: support groups and websites give people a feeling of empowerment

Other related brain disorders include:
Frontotemporal Dementia
Dementia with Lewy Bodies
Parkinson’s Disease

Questions and Answers: (All answers were given Dr. Hermanowicz, unless indicated otherwise.)

Three Disorders (note: though some of the questions are specific to a disorder, the answers are more general)
===========

Q: Is there anything new on stem cell therapy?

A: Stem cell therapy presents great hope to lots of people. Transplantation is further away. Another way stem cell therapy can be helpful is to model the disease. UCI is doing this in Huntington’s Disease.

Stem cell treatment is being tried in MSA-C (“the ataxia type”) in South Korea. These stem cells are being injected into veins, not the brain. But the stem cells find their way to the brain.

Q: What is the relationship between alpha-synuclein and tau, and the effect on them by hsp70?

A: Alpha-synuclein is causing abnormal clumps in MSA while tau is causing abnormal clumps in PSP and CBD. hsp70 is a protein that might help reduce this clumping. It has been looked at in the lab. This may perhaps open up a new avenue of treatment, or something like hsp70. Not yet in clinical trials.

[Robin’s note: You can read the research findings on Hsp70 here:
http://forum.psp.org/viewtopic.php?t=8178
Personally, I think this research will only be of interest to those dealing with PSP and CBD, as the discovery is about tau. And the research was in mice, so we are years away from any clinical trials.]

Q: My wife, with PSP, had an MRI that was inconclusive. What part do MRIs play in diagnosing PSP?

A: A brain MRI is not helpful in diagnosing any of these three disorders. No imaging study is helpful. There are sometimes hints or clues. I would never make a conclusive diagnosis from an imaging study.

Q: My husband, with PSP, fell and fractured his hip. With his impulsivity, how can we help him to understand the safety precautions he must now take to prevent further falls?

A: No medication can help with impulsivity. This requires ongoing discussion and reinforcement with the person with PSP. In some cases, a caregiver is needed 24×7. It doesn’t always need to be the spouse. Perhaps it can be a hired caregiver.

The risk of a fracture or subdural hematoma is always present with falls.

Q: My mother, with PSP, lives in Montana and has never seen a movement disorder specialist. Should we travel to see the leading experts in the US?

A: One does want to be certain about the diagnosis. These disorders are uncommon. If an MD or NP has never seen one of these disorders before, it’s hard to recognize them. I hate to encourage people to travel great distances but it might be at least worth at least one visit with someone in the western US with movement disorder training. Try Boise, ID, or Seattle, WA. This is a problem. It can be gratifying for people to get a diagnosis but it can be frustrating as there’s very little for treatment. Telemedicine is being developed as a technology for diagnosis. I think this could be diagnosed remotely via a camera.

Q: What medicine is the best to treat muscle stiffness?

A: Levodopa is a reasonable medication to try. Baclofen is another possible choice. If it’s localized, injection with botulinum toxin might be helpful.

Q: My wife, with PSP, has a problem with bed wetting. She is in diapers, doesn’t drink liquid after 7pm, and takes medication. What else can I do?

A: Elevating the head of the bed by 30 degrees can reduce urinary urgency. She should be seen by gynecologist or urologist so it’s clear what is causing the problem, though it’s probably related to PSP. Be sure she doesn’t have a UTI. Void the bladder before going to bed. Sometimes incontinence briefs are the best resolution. Consider a bed-side commode or bed-side urinal (for men).

Q: My relative has PSP. Does CoQ10 help? What is it used for?

A: CoQ10 tries to encourage brain cells to get more energy for their operation. UC Irvine is participating in a couple of CoQ10 trials in PD and Huntington’s Disease. But the jury is still out on CoQ10. It’s not known to be effective but it’s not known to be harmful either. I don’t discourage people from taking it.

Q: Is lithium an effective treatment?

A: Lithium is being studied, but it hasn’t been proven to be effective. This medication has potential toxicities. It can have neurological side effects. It has to be monitored closely and used with caution. It is primarily for mood disorders, bipolar disorders.

[Robin’s note: The NIH-funded trial into the safety of lithium in PSP and CBD has ended. Many patients reported unacceptable side effects. To my knowledge, lithium has not been studied in MSA.]

Q: I have been diagnosed with PSP. Can I remain at home (my preference) or must I have to an assisted living facility. Money is not an issue.

A: For many people, money is an issue. Insurance doesn’t cover facility-based care. If you can financially sustain it, the best care is at home. But I discourage the spouse to be the 7×24 caregiver. There is burnout associated with that.

Q: My husband has early-stage PSP, with his full mental capacities. We’ve been discussing the pros and cons of a feeding tube. He insists he doesn’t want one. I and my children would like him to have one. What should we do?

A: His wishes are clear. I do not encourage him to get a feeding tube.

Q: My MD first said I had CBD. Then the diagnosis changed to “slow moving PD.” What is this?

A: I don’t know. This is not a conventional term.

Q: My husband has MSA. There is some 1990 research on the effect of the iron binding protein ferritin. Is there any current info on this?

A: Iron deposits have been associated with neurodegenerative diseases. There’s lots of interest in this topic though nothing has panned out.

Q: I’m a Korean war vet. Would toxin exposure have caused PSP?

Carbon monoxide and manganese exposure can lead to PD. But the great majority of PD, PSP, and MSA cases have no toxin identified yet.

Q: Should levodopa be taken 1 hour before or 2 hours after a meal rather than with meals? If a PSP sufferer is not responsive to levodopa, should the dosage be increased to 2000mg/day?

A: I hate to have people orchestrating medication in relationship with their meals because it’s upsetting to people’s lives.

I don’t usually take people up to 2000mg/day. That’s a huge dose. I might take people up to 600mg/day, perhaps 800mg/day.

Q: My husband has been told by different neurologists that he has MSA or PD. Do I really have to wait for an autopsy report to find out what he has?

A: Yes. Even PD, a far more common disorder, can be hard to diagnose.

If it’s Parkinson’s-like, we use PD medications — whether it’s MSA or PD. No definitive test or clinical exam during life is available.

Q: My mom has one of these disorders and has a problem accepting it. What can I do to make my mother accept her condition?

A: Denial isn’t necessarily a bad thing. There’s nothing specific that can be done to force someone to accept her condition. Perhaps this will change over time.

PSP
===

Q: I have had PSP since December 2008. I have impaired voice and minor walking difficulty. How long do you guess that I have to live?

A: I don’t know. People ask me this. The data says 8 years +/- 4.1 years, but the data may be biased towards severe cases.

Q: My relative has PSP. Why is there such a difference in survival time for different people?

A: According to one study, the average is 8 years, though there is some variability. We don’t know why there is such variability. Perhaps it is connected to why people get the disease in the first place.

Q: What progress has there been in finding out the causes of PSP?

A: This is the thrust of the national study being organized by Dr. Irene Litvan. One of the participating sites is UCLA. This study is underway presently. In terms of progress, there hasn’t been enough. In terms of research, it’s ongoing.

Q: Is there any progress in finding a treatment for PSP?

A: There has been some but not enough. There are studies underway to identify the cause and brain mechanisms involved in PSP. This will lead to better understanding and better treatments.

Q: My husband, with PSP, is currently taking Sinemet, Namenda, and nortriptyline. Are there any new medications effective for treating PSP?

A: Nothing new has been proven to be effective.

Q: My mother died of PSP. What is the incidence of heredity in PSP?

A: I’m guessing that it’s less than 5% of all cases. It’s rare. In some families there is PSP showing up from generation to generation.

Q: My mother passed away due to PSP. My brother has multiple sclerosis. Is there a connection between PSP and MS?

A: Not that we know of. MS is an autoimmune disorder. PSP is not an autoimmune disorder, though there is an immune system component.

Q: My mother has PSP. She cannot walk with assistance. How does the disease progress in later stages?

A: More advanced stages of PSP is “more of the same.” More impairment of speech, more problems walking, more swallowing problems, more cognitive problems. Aspiration can occur with swallowing problems.

Q: I am a urologist (John B in Houston). One of my patients has PSP. What are the urinary problems in PSP?

A: The overwhelming majority of people with PSP have urinary problems (urgency, frequency or incontinence).

Q: I’ve been diagnosed with cerebellar ataxia but it sounds a lot like PSP. What’s the difference?

A: Cerebellar ataxia = sense of incoordination; feeling like you are drunk; irregular speech; poor coordination of walking, arms, and legs

PSP = stiffness of trunk and neck; problems with balance and falling; not the same type of incoordination

They look different.

Research findings: clearing tau in mice by targeting Hsp70

This is a report on some basic research involving the protein tau and an update of sorts of the tau-busting drug Rember.

This University of South Florida press release was posted earlier this week to EurekAlert! Byrd Alzheimer’s Institute neuroscientist Chad Dickey studies how the protein tau can be removed from the brain through drugs or gene therapy. Tau is the protein involved in Alzheimer’s Disease, PSP, CBD, and some other disorders.

A study in mice (genetically modified to develop tau tangles) revealed that inhibiting the protein Hsp70 rapidly reduced the level of tau in the brains. “Hsp70 is a one of several ‘chaperone’ proteins that supervises the activity of tau inside nerve cells. The normal function of tau is to support the structure of nerve cells, much like the skeleton provides a scaffold to support the body. Tau is inside nerve cells, while another hallmark protein associated with Alzheimer’s, beta amyloid, is outside the neurons.”

Several compounds were tested in cell models and genetically modified mice to see if they had any effect on Hsp70. According to the abstract of the journal article about this research, this is the first time that Hsp70 has been targeted and the first time a “newly developed high-throughput screening system” was utiilized.

“One of the more effective Hsp70-inhibitor drugs the researchers discovered was a derivative of methylthioninium chloride, or Rember™, the first experimental medication reported to directly attack the tau tangles in patients with Alzheimer’s disease. Rember™ was heralded as a major development in the fight against Alzheimer’s when results in early clinical trials were announced last year at the International Conference on Alzheimer’s disease. But Rember™ and its derivatives do have some inherent problems; they’re not very potent so effective therapy would require fairly high doses, Dickey said.”

“The drug does help prevent the protein (tau) from clumping together, but that in itself doesn’t mean it’s actively getting rid of the toxic tau,” he said. “Now that we know Hsp70 is a target of Rember™, we can develop similarly-acting drugs that will more specifically target this chaperone protein in affected areas of the brain, resulting in fewer side effects.”

I’ve copied the USF Health press release below. This research was supported by a Pollin CBD research grant from CurePSP. (Abe Pollin has a clinical diagnosis of CBD.) Too bad that the press person at USF couldn’t get the acronym for the disorder spelled correctly (“CDB”) or the disorders CBD and PSP put into the article. (I guess money doesn’t buy accurate publicity.)

I’ve also copied the abstract of the Journal of Neuroscience article.

University of South Florida Health Press Release

Protein inhibitor helps rid brain of toxic tau protein
Laboratory study shows drug targets chaperone Hsp70 to reduce Alzheimer’s protein

Tampa, FL (September 30, 2009) — Inhibiting the protein Hsp70 rapidly reduces brain levels of tau, a protein associated with Alzheimer’s disease when it builds up abnormally inside nerve cells affecting memory, neuroscientists at the University of South Florida found. The study is reported online today in the Journal of Neuroscience.

“Now that we’ve discovered that targeting the chaperone protein Hsp70 can clear tau, it could be helpful in finding more effective drugs for Alzheimer’s disease,” said the study’s senior author Chad Dickey, PhD, assistant professor of molecular medicine who works out of the Byrd Alzheimer’s Institute at USF Health “The therapeutic strategy may also be applicable to other neurodegenerative diseases involving Hsp70, such as Huntington disease, amyotrophic lateral sclerosis (ALS), and some cancers.”

Hsp70 is a one of several “chaperone” proteins that supervises the activity of tau inside nerve cells. The normal function of tau is to support the structure of nerve cells, much like the skeleton provides a scaffold to support the body. Tau is inside nerve cells, while another hallmark protein associated with Alzheimer’s, beta amyloid, is outside the neurons.

Working with researchers at the University of Michigan, the USF team tested the effects of several compounds on Hsp70 in cell models and brain tissue from mice genetically modified to develop the memory-choking tau tangles. Some compounds activated Hsp70, and others were Hsp70-inhibitors.

One of the more effective Hsp70-inhibitor drugs the researchers discovered was a derivative of methylthioninium chloride, or Rember™, the first experimental medication reported to directly attack the tau tangles in patients with Alzheimer’s disease. Rember™ was heralded as a major development in the fight against Alzheimer’s when results in early clinical trials were announced last year at the International Conference on Alzheimer’s disease.

But Rember™ and its derivatives do have some inherent problems; they’re not very potent so effective therapy would require fairly high doses, Dickey said.

“The drug does help prevent the protein (tau) from clumping together, but that in itself doesn’t mean it’s actively getting rid of the toxic tau,” he said. “Now that we know Hsp70 is a target of Rember™, we can develop similarly-acting drugs that will more specifically target this chaperone protein in affected areas of the brain, resulting in fewer side effects.”

The USF researchers originally thought activating Hsp70 would direct the chaperone protein to decrease the tau gone bad — preventing tau from stacking up into tangles inside cells involved in memory and destroying them. But instead of restoring tau to its normal supportive function, activating Hsp70 actually led to tau’s preservation and even more accumulation, Dickey said. “Basically we think the chaperone binds to the tau, and somehow in the process of trying to fix things decides to keep holding onto tau when it shouldn’t. So, activating Hsp70 is not necessarily what we want to do; we ultimately want to inhibit Hsp70 to promote the release or clearance of tau …to kill the bad tau.”

Dr. Dickey emphasizes that problems with Hsp70 alone do not cause Alzheimer’s. It likely develops from a convergence of various factors in the brain, he said, including deposits of the other featured Alzheimer’s protein beta amyloid, or a genetic defect; disruption of cell signaling; a breakdown in the neuron’s support structure, and then accumulation of tau into the memory-choking tangles.

Dr. Dickey’s team at USF focuses on how to manipulate with drugs or gene therapy the chaperone proteins that regulate tau’s fate ­ determining whether it’s preserved or cleared from the brain. The University of Michigan team works on identifying and developing compounds that may be effective against Alzheimer’s disease and other tauopathies.

Journal of Neuroscience. 2009 Sep 30;29(39):12079-88.

Chemical manipulation of hsp70 ATPase activity regulates tau stability.

Alzheimer’s disease and other tauopathies have recently been clustered with a group of nervous system disorders termed protein misfolding diseases. The common element established between these disorders is their requirement for processing by the chaperone complex. It is now clear that the individual components of the chaperone system, such as Hsp70 and Hsp90, exist in an intricate signaling network that exerts pleiotropic effects on a host of substrates. Therefore, we have endeavored to identify new compounds that can specifically regulate individual components of the chaperone family.

Here, we hypothesized that chemical manipulation of Hsp70 ATPase activity, a target that has not previously been pursued, could illuminate a new pathway toward chaperone-based therapies. Using a newly developed high-throughput screening system, we identified inhibitors and activators of Hsp70 enzymatic activity.

Inhibitors led to rapid proteasome-dependent tau degradation in a cell-based model. Conversely, Hsp70 activators preserved tau levels in the same system. Hsp70 inhibition did not result in general protein degradation, nor did it induce a heat shock response.

We also found that inhibiting Hsp70 ATPase activity after increasing its expression levels facilitated tau degradation at lower doses, suggesting that we can combine genetic and pharmacologic manipulation of Hsp70 to control the fate of bound substrates.

Disease relevance of this strategy was further established when tau levels were rapidly and substantially reduced in brain tissue from tau transgenic mice. These findings reveal an entirely novel path toward therapeutic intervention of tauopathies by inhibition of the previously untargeted ATPase activity of Hsp70.
