My 90 year-old Dad was diagnosed with vascular dementia last year and is now in assisted living. I visit him for a week each month (I live out of state) during which time I take him out of the AL facility to go on road trips, fishing, and his favorite restaurants. Whenever we’re out doing things that engage his mind (especially if we’re around other people) he’s fine. The hallucinations began several months ago and were pretty mild. When he would shut off the TV to go to bed he would ask me if I heard the radio playing downstairs. He would go downstairs to check it, saw that it was off, then go to bed. This only happened once or twice a week. Now, whenever he’s sitting quietly at home (or his apartment at the AL facility), he hears what he says is either a “radio playing” or a “voice” talking to him or repeating what Dad is saying. Dad asks me if I hear the voice and gets mad when I tell him that I don’t. The voice tells him stories that make no sense (his mom was in a car crash and is in the hospital…his wife is in the hospital and needs him) all of which are false because they’ve all been dead for many years. He has started to believe the voice and doubt what I tell him. I know the root cause is his brain failing, it’s not his fault, so I don’t let myself get frustrated, and I know it wouldn’t be effective to try to change his behavior. I’m wondering how I should approach this. I’ve tried to redirect his attention back to the ball game we’re watching (he mutes the TV whenever he hears the voice) or talk about something else, but he tells me to be quiet so he can hear the voice. I took him to see his family doctor last week about this issue. He prescribed Seroquel 25mg tablet once in the evening. It helped Dad sleep through the night all this week, but he still hears the voices during the afternoon or evening. Has anyone had any experience with this kind of problem or know of any other drugs that are effective?
