My father is 81yo who suffered a major stroke and is in the beginning stages of dementia. He used to be a truck driver and drove at night which is where his internal clock remains. Needs help with care overnight. Care consists of sitting and watching TV (Heartland, Racing, Nature Shows) with him all night (10pm to 8am) and helping him use the bathroom when he needs to. He can walk when he needs to but prefers to stay in the chair.
