I did not know the possible causes of Alzheimer's. Although it is to suppose that there is something internal and unconscious of wanting to erase our memory and our life. What you say about your father's accident is enough to worry. I have a friend whose mother lived for a long time with this disease and in a carelessness, she left the house and got lost. Thank God they found her on a highway to another city and she was safe and sound. If our parents already need care when they reach a certain age, I imagine they will need more than 100% of our attention with this type of illness. The idea is to give them love, attention and care, Eric. Without forgetting that surely your mother also needs support. A big hug and take care of yourselves. Have a good Thursday, my friend
