talk to a doctor and, if you are lucky, they find something they can cure. If you are unlucky, they find nothing. If you are really unlucky, you find something like an autoimmune disorder - lots of autoimmune disorders get both some inflammation and 'brain fog' or other cognitive issues.
All the diets folks recommend are not really proven to help with things like autoimmune disorders (even though some folks swear by them). If it were that simple, it would be standard treatment and no one would go through the side effects that some of the medicines for autoimmune disorders have. I don't know how effective the diets and supplements are for other things, but I'd not trust it unless it came from the mouth of a medical doctor I trusted.
