Study Title: CFS/ME Negative Symptoms Study (ID:100)

This case-control observational study uses qEEG methods with eLORETA 3D neuroimaging to evaluate the nature and extent of neurocognitive impairment Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME). The primary aims of the study are 1) to assess the neurophysiology between experimental groups with linkage to negative symptoms and behavior to functional systems in the brain and 2) ascertain whether qEEG/eLORETA measurement will provide information that will aid practitioners in assessing long-term outcomes of cognitive impairments within CFS/ME.
