I've noticed that when I overwork my muscles that my thinking abilities dwindle. For instance last night I was cooking dinner and by the end I was walking in circles trying to figure out what to do next. After I took my Mestinon and sat down I gradually recovered. It made me think about a documentary I saw about how cold affects brain function. I don't remember the name of the documentary but it was determined that being exposed to low temperatures can cause a person to became mentally impaired because the body is too busy trying to keep the body warm that the brain doesn't get the resources it needs. I was wondering if that's why my brain seems to take a detour for a while. Maybe my body is trying to take care of the muscles and puts the brain on hold. I'm not a doctor or a scientist -- I'm just speculating.
