Senior Care 81 Year Old Alzheimer's Disease

My dad needs company while my mother is at work. He's just starting to really loose memory and notion of the loss and he's getting lost a lot but is stubborn and still wants to drive and be independent. We need someone to be with him and remind him of his everyday and make sure he doesn't get hurt. He is 81 and still cares for himself to a certain level. My mother makes sure he takes showers everyday but he showers himself, same with food and his medication. Let us know if you could be able to keep him company and take him to the mall, the movies, and doctors appointments.
