I have been struggling with recurring bouts of brain fog recently, feeling tired even though I slept through the night and trailing off in conversations. Not being able to remember things that were said only a few minutes ago either by me or someone else and losing my train of thought easily. Frankly I feel dumber than usual like I can't think straight. I think it worries me because I have had long bouts of severe insomnia in my life and have had a couple concussions in my life, that combined with my maternal grandmother's severe dementia has made this concerning to me.
