To my knowledge we have never discussed dementia and/or alzheimers disease(s) as they may relate to pool. So, a friend who has profound dementia came into the poolroom with her girlfriend. She played pool somewhere areound a "6" APA or low 500's Fargo rating. She couldn't remember me or her own name but after a little discussion I threw out the balls for nine ball on a table and gave her a cue to see what would happen. She began to run the balls off in rotation, chaulk the cue between shots and attempted to play position. When I called out her name she didn't respond at all. I took the cue away from her and she just stood there without expression and her girl friend took her home. I know that old memory is usually the last o go but I was curious about the pool she played and her efforts to run out etc. Does anyone have any ideas about how pool has affected anyone they know who has dementia?
