My wife arranged for a person to come to her uncle's nursing home once a week to play music for him. He suffers from fairly severe dementia, but during these sessions he relaxes and "lights up", its the best thing in the world for him. It is a great way to bring joy to someone.
I used to do Rec Therapy at a home for people with dementia and started playing some old folk songs for them after reading how music can help. It really does seem to bring them back.
