Mum had to be sectioned at A&E following myself ringing ambulance because of aggressive behaviour and acting very oddly. Only then did the family find out she had a diagnosis of dementia five years ago and she withheld it from us. Obviously we new she had memory problems but recently been paranoid and verbally aggressive to dad and myself. Unfortunately dad has had enough and has said he does not want her back home - I think things have been very bad at home and he has not mentioned anything. Apparently she has not been eating and he did not tell anyone, she has not been cleaning or showering etc. I visit o?.nce of twice a week and noticed the memory and house not being as clean as usual but she always had a chat and made a cup of tea so it has been something of a shock. The hospital now done a DOLS because she will be a danger to self and others and there is a best interests meeting next week. I don't know what to do about dad as he refuses to have her back (that's another issue again for me to deal with i.e. a father who is so disloyal to mum after 57 years). Does anyone know what social services will say? Do I need legal advice etc. She has told me she wants a flat and not a care home (in the moments when she has flashes of insight). I think her dementia has suddenly got worse because she was not like this a month ago. Any advice would be appreciated.
