Warning for those with dementia about anticholinergics

Like Alzheimer’s Disease (AD), those with many other types of dementia have an imbalance of acetylcholine in the brain.  Anticholinergic drugs can be problematic for those with AD and non-AD dementias.

I saw this Q&A recently in my Dad’s AARP Health Care Options newsletter called fyi.

Question:  My husband has Alzheimer’s disease.  His pharmacist told me that certain medicines could further worsen his memory problems.  Any advice?

Answer:  …You are wise to take steps to ensure that your husband’s mental status is not worsened by the effects of his medicines.  As we have mentioned in previous columns, many of us become more sensitive to medicines as we age.  As a result, a variety of medicines could produce unanticipated effects that could worsen mental status and overall function.

Alzheimer’s disease is characterized by low levels of a chemical that transmits signals between nerves called “acetylcholine.”  As a result, medicines called “anticholinergic” drugs that block the effects of this nerve chemical can be especially problematic for people with Alzheimer’s disease.  Unfortunately, these drugs are very common.  They include:

* Certain antihistamines such as diphenhydramine (Benadryl)
* Certain antidepressants such as amitriptyline (Elavil) and doxepin (Sinequan)
* Medicines for bladder problems such as oxybutynin (Ditropan)
* Muscle relaxants such as carisoprodol (Soma), cyclobenzaprine (Flexeril), and methocarbamol (Robaxin)

I always say to write down the name of every medicine that you or your loved one is taking, and review this list regularly with your doctor and your pharmacist.

“Understanding Difficult Behaviors”- recommended book

This post might be of interest to those who have loved ones with dementia — all of the LBD, some of the PSP, and some of the CBD (especially late stage) folks…

There are a couple of great books with practical suggestions on how to cope with Alzheimer’s Disease and similar illnesses. One is “Understanding Difficult Behaviors” by Anne Robinson, Beth Spencer, and Laurie White, 1989, published by Eastern Michigan University.

You can purchase the book at local offices of the Alzheimer’s Association, which are in Mountain View, Lafayette, San Rafael, Sacramento, Santa Cruz, etc.

The difficult behaviors this book deals with are: angry, agitated behavior; hallucinations, paranoia; incontinence problems; problems with bathing; problems with dressing; problems with eating; problems with sleeping; problems with wandering; repetitive actions; screaming, verbal noises; and wanting to go home.

Copied below are some excerpts from the four-page section on “Screaming, Verbal Noises.”

Excerpts from

“Screaming, Verbal Noises”
in
Understanding Difficult Behaviors

by Anne Robinson, Beth Spencer, and Laurie White
1989
Published by Eastern Michigan University

POSSIBLE CAUSES

Physiological or Medical Causes
* hunger
* incontinence (wetness, etc)
* need to go to the bathroom
* fatigue
* need for help changing position in bed or wheelchair
* vision or hearing loss that causes misperception of the environment
* impaired ability to speak or be understood
* acute medical problems that result in feeling ill or pain and discomfort

Environmental Causes
* too much noise
* overstimulation or sensory overload
* use of physical restraints
* upset by behavior of other residents

Other Causes
* procedures which are uncomfortable or not understood, such as having an enema, having a dressing changed, being catherized, etc.
* bathing – person may be cold or feel exposed
* dressing – person may be cold or feel exposed
* purpose of mouth care not understood
* touch/turning/repositioning – uncomfortable or not understood
* fear/anxiety
* feeling threatened
* need for attention
* frustration
* boredom/lack of stimulation

COPING STRATEGIES

* Have a good medical evaluation to check for illness, infections, pain/discomfort, or impaction

* Provide adequate meals/snacks to minimize hunger

* Institute regular toileting schedule to minimize incontinence

* Change promptly after incontinent episodes

* Try rest periods to minimize fatigue

* Make sure there are frequent (at least every 1-2 hours) position changes if person is bedridden or restrained in chair

* Maximize sensory input. (Check to see whether hearing aids and eyeglasses are in place and working properly.)

* Lower stress; create a relaxing environment:
– minimize noise
– avoid overstimulation/sensory overload
– avoid use of restraints
– play soft, soothing music

* Use relaxation strategies to minimize fear, threat, anxiety. For example:
– try massage/therapeutic touch, stroking person’s head, arms, hands
– try placing your arms around the person and gently rocking back and forth
– talk in a soothing voice
– play soft, soothing music or soothing sounds such as tape of rainfall, waves breaking on shore, etc.

* Try these communication suggestions:
– approach person with soothing voice; call person by his/her name; identify yourself
– explain/prepare person for what is to be done using simple, clear, short sentences
– break task into short steps briefly explaining each one
– think of other ways for the person to communicate, such as using a bell. This can enhance the person’s sense of security by feeling that he/she is able to communicate needs to caregiver

* For staff in long term care settings:
– use consistent routines for activities such as bathing, meals, getting ready for bed; keep to the same schedule each day
– identify staff who work well with certain individuals. Consistency in staffing is important.
– plan time to socialize with the person for a few minutes in addition to assisting with activities of daily living
– encourage participation in meaningful activities to minimize boredom and frustration.

* Softly read to person.

* Medication should be used cautiously when other interventions have been unsuccessful and when the vocal behavior is very stressful to the caregiver(s) and/or residents living in the area. This medication should be monitored carefully by a physician/psychiatrist.

OTHER CONSIDERATIONS

Vocal behaviors are most commonly seen in the later stages of progressive dementia. Many people who shout or cry out are physically immobile – wheelchair or bed-bound. The underlying problem is the person’s inability to communicate his/her needs, wishes, thoughts, etc.

 

April 2005 FDA Warning on Antipsychotics w/Dementia

This FDA black box warning from April 2005 applies to everyone with
dementia.

It addresses these medications: olanzapine (Zyprexa), aripiprazole
(Abilify), risperidone (Risperdal), quetiapine (Seroquel), clozapine
(Clozaril), ziprasidone (Geodon), and Symbyax.

Here’s the FDA warning from last year:
https://web.archive.org/web/20050423213000/http://www.fda.gov/cder/drug/advisory/antipsychotics.htm
FDA Public Health Advisory
Date created: 4/11/05
Deaths with Antipsychotics in Elderly Patients with Behavioral Disturbances

The Food and Drug Administration has determined that the treatment of
behavioral disorders in elderly patients with dementia with atypical
(second generation) antipsychotic medications is associated with
increased mortality. Of a total of seventeen placebo controlled trials
performed with olanzapine (Zyprexa), aripiprazole (Abilify), risperidone
(Risperdal), or quetiapine (Seroquel) in elderly demented patients with
behavioral disorders, fifteen showed numerical increases in mortality in
the drug-treated group compared to the placebo-treated patients. These
studies enrolled a total of 5106 patients, and several analyses have
demonstrated an approximately 1.6-1.7 fold increase in mortality in
these studies. Examination of the specific causes of these deaths
revealed that most were either due to heart related events (e.g., heart
failure, sudden death) or infections (mostly pneumonia).

The atypical antipsychotics fall into three drug classes based on their
chemical structure. Because the increase in mortality was seen with
atypical antipsychotic medications in all three chemical classes, the
Agency has concluded that the effect is probably related to the common
pharmacologic effects of all atypical antipsychotic medications,
including those that have not been systematically studied in the
dementia population. In addition to the drugs that were studied, the
atypical antipsychotic medications include clozapine (Clozaril) and
ziprasidone (Geodon). All of the atypical antipsychotics are approved
for the treatment of schizophrenia. None, however, is approved for the
treatment of behavioral disorders in patients with dementia. Because of
these findings, the Agency will ask the manufacturers of these drugs to
include a Boxed Warning in their labeling describing this risk and
noting that these drugs are not approved for this indication. Symbyax, a
combination product containing olanzapine and fluoxetine, approved for
the treatment of depressive episodes associated with bipolar disorder,
will also be included in the request.

The Agency is also considering adding a similar warning to the labeling
for older antipsychotic medications because the limited data available
suggest a similar increase in mortality for these drugs.

Here’s an article written on the FDA warning in the “Senior Journal”:

FDA Warns Antipsychotic Drugs Dangerous to Elderly With Dementia

April 14, 2005 – The Food and Drug Administration (FDA) this week issued
a public health advisory to alert health care providers, patients, and
patient caregivers to new safety information concerning an unapproved
(i.e., “off-label”) use of certain drugs called “atypical antipsychotic
drugs.” These drugs are approved for the treatment of schizophrenia and
mania, but clinical studies of these drugs to treat behavioral disorders
in elderly patients with dementia have shown a higher death rate
associated with their use compared to patients receiving a placebo
(sugar pill).

The advisory applies to such antipsychotic drugs as Abilify
(aripiprazole), Zyprexa (olanzapine), Seroquel (quetiapine), Risperdal
(risperidone), Clozaril (clozapine) and Geodon (ziprasidone). Symbyax,
which is approved for treatment of depressive episodes associated with
bipolar disorder is also included in the agency’s advisory.

FDA is requesting that the manufacturers of all of these kinds of drugs
add a boxed warning to their drug labeling describing this risk and
noting that these drugs are not approved for the treatment of behavioral
symptoms in elderly patients with dementia. Patients receiving these
drugs for treatment of behavioral disorders associated with dementia
should have their treatment reviewed by their health care providers.

In analyses of seventeen placebo-controlled studies of four drugs in
this class, the rate of death for those elderly patients with dementia
was about 1.6 to 1.7 times that of placebo. Although the causes of death
were varied, most seemed to be either heart-related (such as heart
failure or sudden death) or from infections (pneumonia).

The atypical antipsychotics fall into three drug classes based on their
chemical structure. Because the increase in mortality was seen with
atypical antipsychotic medications in all three chemical classes, the
agency has concluded that the effect is probably related to the common
pharmacologic effects of all atypical antipsychotic medications,
including those that have not been studied in the dementia population.

The agency is considering adding a warning to the labeling of older
antipsychotic medications because limited data also suggest a similar
increase in mortality for these drugs. The review of the data on these
older drugs, however, is still on-going.

You can find patient information sheets and healthcare provider sheets
on all of the drugs mentioned at this FDA web page:

Caregiving for those with Dementia – Class Notes

This post will be of interest to those who are caring for people with dementia…

I attended the 4-week class on caregiving for those with dementia at Avenidas in Palo Alto this month (May ’06). The class, called “It Takes Two: Dealing with Dementia-related Behavior,” was run by the Family Caregiver Alliance (caregiver.org), an SF-based organization that offers classes, resources, and counseling to those throughout the SF Bay Area and nationally.

A Dementia Fact Sheet was handed out. It states:

“[The] term ‘dementia’ is used by the medical community to describe patients with impaired intellectual capacity… Signs of dementia include short-term memory loss, inability to think problems through or complete complex tasks without step-by-step instructions, confusion, difficulty concentrating and paranoid, inappropriate or bizarre behavior. Clinical depression also may accompany early signs of dementia.”

In the first class, we discussed dementia. I think I wrote these statistics down correctly:
* 10% of people older than 65 have AD or dementia
* over the age of 85, almost 50% of the people have AD or dementia

There are reversible dementias and irreversible ones. The importance of getting a diagnosis was made clear by the fact that some dementias are reversible. In the first class, different diseases with dementia components were discussed, beginning with AD. LBD and PSP were both discussed.

Though it was not distributed, I think this publication summarizes the information presented the first day of class:

www.caregiver.org/caregiver/jsp/content_node.jsp?nodeid=569

Lots of FCA-authored materials were handed out at the first class, including:

1. Dementia – Fact Sheet: I can’t find this on their website. It lists possible causes of dementia (deteriorating intellectual capacity) including reactions to medications, emotional distress, metabolic disturbances, nutritional deficiencies, etc.

2. Alzheimer’s Disease – Fact Sheet: this is available on their website at:

www.caregiver.org/caregiver/jsp/content_node.jsp?nodeid=567

The fact sheet breaks AD into three stages and describes the dementia-related behaviors of each stage.

Note that the Dementia with Lewy Bodies – Fact Sheet on their website is woefully out of date. I’d suggest getting the latest info from the LBDA website. In particular, this brochure is excellent for caregivers, MDs, etc:

www.lewybodydementia.org/docs/brochure/3_brochure.pdf

3. Tips for Interacting with a Person with Dementia: I can’t find this on their website. The tips are:
* Reassure, reassure, reassure
* Try to remain calm
* Do not disagree with made up stories
* Give compliments often
* Respond to the person’s feelings, not their words
* Use distractions
* Do not try to reason with the person
* Give yourself permission to alter the truth
* Avoid asking questions that rely on short term memory
* Break down all tasks into simple steps
* Respond calmly to anger, don’t contradict or argue

4. Tips on Interacting with Persons with Alzheimer’s Disease or other Dementias (pages 1-3) and Qualities of Friendship in Relation to Someone with Dementia (page 4). I can’t find this on their website.

5. Principles for Understanding and Communicating with a Person with Dementia. I can’t find this on their website. The five principles are:
* Knowing and accepting the cognitive limitations of the person will help you set realistic expectations of the person’s behavior.
* Understand that OUR thoughts, attitude, and actions significantly impact on the behavior of the person with dementia.
* Recognize that behavior, even in a confused person, more likely results from a cause. It is triggered.
* Learn that to enhance communication with a person with dementia requires a commitment to remain “connected” regardless of the content of the conversation.
* Understand that changing behavior takes time, effort, and patience. Reward yourself often for working towards change.

6. A Reference List for Families and Professionals – Caring for Individuals with Dementia: I can’t find this on their website. It’s a list of books on family caregiving and dementia care.

7. Caring for Adults with Cognitive and Memory Impairments – Fact Sheet: this is available on their website at:

www.caregiver.org/caregiver/jsp/content_node.jsp?nodeid=392

The other three classes are hard to summarize. Basically we discussed and role-played communication strategies based on the tips and principles listed above.

This class will certainly be taught again in the Bay Area. It was taught in April in SF, I believe. And then the May class was in Palo Alto. My guess is that it will be taught again in the fall. You can check in periodically with the FCA’s website listing of classes to learn what’s available:

Points from an expert physical therapist – on PD and parkinsonism

I attended Marilyn Basham’s presentation this afternoon on “Caregiving Made Easy for Parkinson’s Individuals.”  She’s the physical therapist (PT) at The Parkinson’s Institute (TPI).  I picked up a few tidbits at the presentation that I thought I’d pass along.  As the presentation was focused on Parkinson’s Disease (PD), not everything applied to the situations we are dealing with but there were still many interesting points that apply.

Here are the points I found interesting….  (with some of my comments in parantheses)

People with PD and Parkinsonism MUST use a walker or wheelchair to make them as safe as possible.  It’s very important to have mobility and postural strategies worked out with a physical therapist and/or neurologist.

PD is evident when 60-80% of the cells in the basal ganglia have died.

The “automatic motor programs” we have are stored in the basal ganglia.  One of these “programs” is what tells us that to stand up from a low chair, we need to scoot to the edge, put our feet underneath us, lean forward, and push up.  PD folks must either receive cues as to the steps of these programs, or they must practice it so many times that doing it becomes somewhat automatic again.

To overcome freezing (called “gait initiation failure”), you can put masking tape on the floor to provide a visual cue.  Put the tape at thresholds or where ever the person often has the freezing problem.  (Of course this won’t work for those with PSP who have downward gaze palsy.)

A suggested verbal cue to give someone who wants to speak is:  “Swallow.”  (pause to let the person swallow)  “Take a deep breath in and then, at the top of your breath tell me what you want.”  (pause to let this happen)  Swallowing is important because fluid accumulates in the back of the throat and those with PD are not aware of it.  You can give them gum to initiate a swallow response.

Before someone with MSA (or PD with blood pressure fluctuations) stands up, give them a glass of water with salt in it or Gatoraid.  This will increase the blood pressure.  Obviously the person’s diet and blood pressure medication needs to be taken into account before following this suggestion.

We must give time for those with these diseases to process information!  Be patient!  Give long pauses.  Don’t overload them.  Don’t give them more than one complex task at a time.  Walking is a complex task.

(Some of you know that my father and I communicate by our holding up fingers to designate an answer.  Example, “do you want 1 for coffee, 2 for tea, or 3 for nothing,” and I hold up 1, 2, and 3 fingers.  He answers by holding up fingers.  Long after the fingers come up, he may try to verbalize the answer.)  I asked Marilyn why my father could hold up fingers faster than he could verbalize a response.  Marilyn said she didn’t know why but pointed out that parents of small children teach their children sign language long before the children can verbalize.

Dementia is rare in PD.  (It’s definitely common in the Atypical Parkinsonism diseases.)  PD folks may lose their keys but they still remember what keys are and how to use them.  (I thought that was a good story for remembering what dementia is.  My dad, for example, cannot remember how to use an ATM card.  I see the dementia very clearly.)

A patch for Sinemet is in the works.  (Some of your loved ones take Sinemet.)

The head of TPI thinks that PD is the most curable of all the neurodegenerative diseases.  (Let’s hope he’s right because hopefully those diseases related to PD can be cured quickly too.)

Regards,
Robin

Large display clock

This is in the category of a small tip….

My dad (with PSP) had been getting up in the middle of the night, thinking it was morning.  Probably most of the time this happened he fell because he’s very tired and unsteady on his feet at the wee hours.  Over half of his falls used to occur at 3am or 4am.  I had been addressing the “cause” of the falls.  For example, he would often fall at 3am while putting on his robe in the bathroom.  I moved the robe to right next to his bed so he can put it on while sitting down.  But then I addressed the larger issue of why he gets up in the middle of the night.  I learned that he could not read the time on his alarm clock any more.  The display was too small.

I went to the Peninsula Center for the Blind and Vision Impaired (PCBVI) in Palo Alto, CA and found a large display clock for $26.75.  Their supplier is MaxiAids (www.maxiaids.com or 800-522-6294), who sells the clock for the same price.  It’s item #74852 – AM-FM Clock Radio with Extra Large LED Display.  The numbers are green.  Turns out that some low-vision people can see green better than they can white or red.  Anyway, this clock solved the problem of not knowing what time it was in the middle of the night.  Dad no longer gets up at 3am or 4am so those falls have been eliminated.  (Unfortunately there’s still lots of other falling!)

The PCBVI and MaxiAids also have clocks that talk (say the time).  We might have to go that route if Dad’s vision problems worsen.
