My husband has Parkinson's and fluctuating attacks of hallucinations. Any advice?

Catgirl, is there a lawyer in your area who specializes in "elder law?" He or she might give you an hour consultation and some useful advice to first get the finances and assets in your control, and then how best to help him. You will need to protect yourself physically if the hallucinations cause him to act out. It's possible an adjustment of meds could with that too. Is he under doctor's care for the parkinsons? He may not be able to reason through this with you and so you need to bring in help for yourself first. If you aren't getting sleep, you cannot help him. My heart goes out to you in this struggle. My hubby has PD too.

Check into a memory care facility for him. Some assisted living places over different levels of care for spouses with different levels of abilities. Do you have any relatives or friends you can ask for help? If he won't agree to go or get more help at home you'll have to get some legal help to get POA or guardianship. At 75 years old you need some help before you damage your health.
