Had similar after being exposed to prolonged natural gas. My memory and cognitive function were completely crap. Eventually figured out I had a genetic disorder that got activated by the gas. “factor 5 “Leiden” which is fairly common and usually not an issue, but environmental toxins can trigger it. Result is my blood went very “sticky” So I was suffering micro clots / minor strokes multiple times week. Went on blood thinners and my cognitive problems resolved. Was an insane road to figure this all out.
