My perception, and that of my mum's cleaner too, is that mum is much worse, in the sense of being more confused and feeling ill, when she drinks and when she eats a lot of sugary stuff. As far as the alcohol is concerned, I'm not talking about binge drinking, although I'm not sure how much she does drink, probably between one and three units a day. The sugar is in biscuits and chocolate, that she can eat a lot of, despite having Type II diabetes. The last time I stayed with her I 'banned' sugar and alcohol -- threw away everything in the house. She was very cross with me, but mentally she sharpened up a lot. I was then undermined by the diabetic nurse at her surgery, who said that 'at mum's age' it didn't matter if she had a taste for sugary foods. Are we right, or does the sugar and alcohol have no implications for her dementia, even if it does for her diabetes?
