Mum lives on her own, has carers 3 times a day and a family member visiting for at least 3 hours every day for last 18 months but now is not enough. Wanders alot, Confused, agitated, unable to cook / make a drnk/ walk her dog and differentiate between reality and TV. Gets very agitated and carers have advised residential care. Mum will not consider despite getting hit by car crossing road. Doctor says cannot make her. Do not know what to do as family can do no more and she is danger to self. Any advice?
