My Mother-In-Law has Alzheimers, she has no short term memory, but can talk about things that happened years ago. She has now started to become aggressive with my Father-In-Law, particularly if he leaves her for a short time, she really shouts and becomes very upset and abusive. After months of the whole family burying their heads in the sand and hoping all will go away, i really feel that action needs to be taken. Has anyone got any advice they can offer, they are both in their 80's and it is becoming increasingly difficult for my Father-In-Law to cope with her, but she refuses to leave the house, where do we start, help please.
