My partner's mother has had mental health problems for years which were always referred to as 'episodes', when these occurred she would rant and rave a lot. It was accepted that this was just her personality and was 'put up with' by the family. Over the last couple of years her health and mental state has deteriorated and we have now been told by Dad that she has Alzheimer's and he has to 'just ride with it' . She has always been very controlling and Dad keeps the peace by doing whatever she tells him...or so I believe. Recently they disappeared on holiday (x2 80 odd year olds towing a caravan) refusing any contact during or since returning. We have found out that Mum has pulled the phone out of the wall and taken Dads mobile phone away. We are planning to visit at the weekend and have no idea how to handle a seemingly out of control situation............any advice?
