I know this is not a new topic. Too mentally fatigued/overstimulated to do search. Does anyone else feel most worse just when trying to talk (especially while sitting upright), process images, compose a paragraph than doing menial physical tasks? It is not just the brain fog but complete meltdown, agitation, achy feeling, complete overstimulation and mental fatigue. Golstein once wrote of a patient that had to quit school because of mental fatigue but could still run the marathon. This greatly exagerates my condition as physical fatigue and OI are disabling. But it often easier for me to do some laundry, wash dishes, or walk around block and sometimes even more than just have a normal conversation or process images, etc. i don't know how a healthy person can understand this and I still have to try and describe it to family, doctors, disability. In terms of treatment i've gotten limited help from Goldstein's ideas, nitroglycerin (very temorary) and nimodipine (not consistent response and expensive). Not sure what response I am looking for just tired of symptoms and having to keel describing them to famiky, doctors and disability.
