Is it me, or does there seem to be a connection between thyroid disorders and Alzheimer's? My dad had a thyroid condition which went untreated for a number of years which resulted in him losing weight and developing paranoia and a detrioration of his mental health. This was finally treated with radioactive iodine, and various medications. Since then his weight fluctuated dramatically and his mental health didn't really recover. About 18/24 months ago he was diagnosed with Alzheimer's. I've been trying to read up on the condition and he doesn't seem alone in having thyroid problems and then developing Alzheimers. Anyone else of the same view? Sorry if I'm merely repeating the obvious. Also, I've read the factsheet on eating, and it mentions appetite on there. My dad could eat for England and my mum has to keep an eye on him to stop him gaining too much weight - he already has cholesterol problems and high blood pressure. Again, any suggestions/observations on this? Many thanks.
