In the brain, serotonin is a neurotransmitter and regulates arousal, behavior, sleep, and mood, among other things. [9] During prolonged exercise where central nervous system fatigue is present, serotonin levels in the brain are higher than normal physiological conditions; these higher levels can increase perceptions of effort and peripheral muscle fatigue.

The histologic findings are diffuse, irregular loss of axons and myelin accompanied by widespread gliosis, tissue death due to an infarction or loss of blood supply to the brain, and changes in the plasticity of the arteries. The pathologic mechanism may be damage caused by severe atherosclerosis. The onset of this disease is typically between ...
