My mother cares for my father full time apart from Mondays and Wednesdays for a few hours when he attends day care. He was diagnosed as an Alzheimers sufferer about 5 years ago. I have been reading much of your website regarding the progressive degenerative state of the patient and until recently I felt that my mother was coping. (My father is 74 and my mother is 66). I am now worried for her safety (a diabetic) because my father has started to become violent, something total out of character even 6 months ago. My mother has bruises on her body from where he has kicked her and he has even held her up against a wall and threatened her. He sometimes crys afterwards because he has realised what he has done. They have been together since 1957 but married in 1962. I am worried that she is going to have a heart attack or something similar. My father also has a hernia and prostate cancer which is being controlled but this does not stop him doing what he does. Is my mother's safety at risk so much that she must consider care for my father. What can I do without interfering.
