David Cassidy Battling Dementia

This is a hard video to watch, especially for those of us who grew up with "The Patridge Family"-

First thought? He appears drunk.  And he has a history of DUI and rehab.  But he tells PEOPLE he's decided to stop touring and performing, so he can deal with his illness.

Another "Partridge" wishes him well-

David Cassidy once had a bigger fan club than Elvis & the Beatles. If you're a fan, now is a great time to send him your love & best wishes.
