My dad suffers from mild Dementia and he was always an active guy. He loved to play cards and be outdoors and now he would rather spend time watching the news. I have blocked most news channels(cuz it makes him negative) and he has a caregiver for 6 hrs a day. I am looking for activities that he can be involved in that will keep him active both physically and mentally. He has recently tried checkers after years of not playing and gets frustrated. Any thoughts?
