Hypersexuality and PSP?

I received this question via email today:

Did you find or have you heard anything about heightened sexuality with PSP patients, for older and more challenged patients, specifically women who find a need to masturbate?

My answer is:

As I’m pretty sure I’ve discussed elsewhere on the Forum, my father did grab CNAs and private caregivers we had hired in inappropriate places (breasts, crotch). This was not in keeping with his past prudish/modest/respectful behavior. Because PSP can affect the frontal lobe, society’s rules are somewhat out the window. There is a lack of inhibition. And certainly hypersexuality is possible.

You may have luck treating this with a mood stabilizer. But it’s likely refractory to medication. Well, you can sedate the person but this is typically unacceptable to many.
