Outline of Final Research Achievements

We investigated the associations among neuroinflammation, functions and structures of the brain and oxidative stress in order to clarify the molecular and neural mechanisms of chronic fatigue. In consistent with our previous findings of the pathology of chronic fatigue syndrome, we observed the enhancement of oxidative stress, impairment of endocrine function and neuroinflammation in a novel animal model of chronic fatigue. Atrophies of the widespread brain regions in human with chronic fatigue were observed using magnetic resonance imaging (MRI). In addition, we found that the pattern of neural activities of the brain in the resting state was significantly changed using magnetoencephalogram (MEG).
