Mum has had Alzheimer’s for about 5 years. For the last 6/9 months she has started going to the local shops during the night. She is often waiting outside for the newsagents to open when the staff get there at 5.30. She goes into the hairdressers 3 or 4 times a day often because she thinks she is starting work there. She has been in respite care home for 2 weeks but social worker wants to send her home! She is not safe at home! What do I do?
