My moderately dementia stricken dad is often found sitting in the parked cars in the driveway, at all times of morning, day and evening, which by the way, the cars are all in his name. His job, as owner, included driving daily, most of the day. The van was basically his main office. I take him with me practically everywhere, including his company, which continues to operate under my supervision. Often I feel like giving in and letting him drive around the neighborhood for grocery store or car wash runs. Would that make matters significantly worse or help take the edge off so he can accept it more? He will not listen to reason of terrible possibilities of crashes and fatalities. He is greatly challenged to drink enough to not experience headaches and slight dizziness. He hallucinates quite a bit throughout most days although mostly the early morning or evenings is when he has major hallucinations. I am miserable for him but I don't show it and I stay firm. Is there a better way to handle this?
