Wonder if anyone knows if there is any connection between Alzheimer's and autism? Mum has started a lot of hand flapping lately, similar to an autistic child I once taught. Also, Mum seems to be two people - generally happy and bidable, but when she enters the toilet she becomes someone else!! Unco-operative, nasty, sometimes violent and then suddenly everything is sweetness and light again. Seems unconnected to the need for the toilet. Once she has relieved herself she just sits tearing paper, or her clothes! and woe betide anyone who tries to stop her!Any advice please? I dread taking her to the loo, especially in the night as trying to get her out and back to bed can take an hour or more. Can not leave her as she would probably stay there all night! Thanks.
