This is unscientific anecdata, but my dad had celiac disease. After a few years, he got "bored" of it and refused to go along with the diet. Within a couple of years, he got vascular dementia (at a relatively young age) and ended up having a brain haemorrhage. The studies are pretty early stage on finding connections between celiac disease and brain damage but the TGM6 protein, common in people with gluten related sensitivities, has been implicated. So, and this is all spitballing for now, I think diet, and inflammation in particular, could prove to be a big deal. At least, I believe it's not following the diet that "got him", as it were.
