My 70-year-old father refuses help. He can't even walk depending on his medications, should I insist?

Parkinson's itself will cause hallucinations and Dementia will happen. Me, I don't like to continue to fight with someone. Your Dad not being able to walk is also from Parkinson's. Maybe its time for LTC. Your father is not going to get better. He may get very hard to handle. As said, if he hasn't seen a doctor in a while, time for nrpew testing and labs.

someone1, I see by your profile that your Dad has Parkinson's. When was the last time he saw his primary doctor? If it has been awhile, time for a check-up, and to let the doctor know of the side effects that Dad is having.

Your Dad could have an Urinary Tract Infection [UTI] which can also cause a lot of different side effects including hallucinations. An UTI can be treated. It's an easy test, Dad just needs to pee in a cup. The results can be given the same day or the day later.

Do you live with your 70 year old father?
By today's standards he is young, so there must be some underlying diagnoses here?
Can you tell us a bit about your Father's physical condition, his underlying illnesses, and his mental condition.
As far as insisting others do as we wish they would do, we can insist anything we want; but that won't change that it is an individual's individual decision that determines what he or she does or doesn't do.
Hope you will fill us in a little.

Wow. This is A LOT! You must be so stressed out. It sounds like he needs some serious med changes and that might be best done in a facility so that he can be monitored and med changes can be made very quickly. I don't see how you can handle this at home.

Sounds like dad needs to be in managed care of some kind at this point. How can you continue living in this situation where you need to break his door down to give him medication which causes hallucinations? You have a crisis waiting to happen with him, so I'd get him placed if I were in your shoes. He seems to need more help than you alone can manage. If he were living in Skilled Nursing, for instance, he wouldn't be able to lock himself in his room, he'd be fed meals on a schedule, and he'd get his medications administered to him on a schedule as well, along with showers and all the rest of the regular ADLs.

Good luck!
