My father has vascular dementia and heart disease. (mild dementia) But he has lots of energy and he is always making plans to go out of the house. Everyday he will say he needs to go to the bank, to the store, to the supermarket, to visit etc, a friend, etc. The point is he can´t go outside alone or he will have trouble coming back. And I don´t have time to carry him everywhere. All I can do is have a short walk with him everyday.
