Hi , im new to the forum and have come on here to see if anyone can answer my question , ive just been watching daybreak and they had an American doctor on there saying that people with Alzheimer's have a diabetic brain , because Alzheimer's is caused by glucose not being able to get to the brain cells , I'm a type 1 diabetic on a pump and have has diabetes 32 years , does anyone know if there is evidence to support this ? This has really worried me as both my grandparents had Alzheimer's .
