My husband has alzheimers. He is stille working ...but....he is absolutely drained when he gets home. Eats with closed eyes (he is tired)....sleeps for more than an hour every afternoon....gets up and is fine again. He says he is afraid the brain will stop working if he stop his work. Me and the kids feel that he is forcing the brain to think and it is not good for the brain to be forced like that. Your comments please!!!!
