Well, Roger, my father who is 80, just about helpless, can barely see, can't stand up, and certainly gets frustrated and angry, also has been known to laugh and smile a little, so I would have to say he is not depressed. He has had PD for a few years. He has the kind of PD that makes movement almost impossible, with very little tremor. I have one other idea, which might or might not apply, I find music improves my mood, but it has to be music that I like, not necessarily what someone else likes. What I am suggesting is to get a walkman type tape player and some tapes of your dad's favorite music, and see if he responds.... My father is a musician, and played with a band in the 40's and I made a collection of the records of that he performed on, recorded them on cassettes. One day he was in the car, and I popped in one of the tapes, he was dancing around in the seat, it made me feel so good to see that. Good luck in your efforts. [log in to unmask]
