- 2012, Basant Puri, et.al., found in a MRI study: "significant neuroanatomical changes occur in CFS, and are consistent with the complaint of impaired memory that is common in this illness; they also suggest that subtle abnormalities in visual processing, and discrepancies between intended actions and consequent movements, may occur in CFS."
- 2014, A Japanese PET study looked at neuroinflammation in 9 patients with ME/CFS and 10 controls. They measured a protein expressed by activated microglia, and found that values in the cingulate cortex, hippocampus, amygdala, thalamus, midbrain, and pons were 45%–199% higher in ME/CFS patients than in healthy controls. The values in the amygdala, thalamus, and midbrain positively correlated with cognitive impairment score, the values in the cingulate cortex and thalamus positively correlated with pain score, and the value in the hippocampus positively correlated with depression score.
- 2014, The Stanford ME/CFS Initiative, directed by Dr. Jose Montoya and working with Dr. Michael Zeineh and colleagues, studied the brains of patients with CFS and healthy people and found distinct differences between the two groups. Radiology researchers have discovered that the brains of patients with CFS have diminished white matter and white matter abnormalities in the right hemisphere.
- 2016, A six year longitudinal MRI study found that Chronic Fatigue Syndrome (per Fukuda & Canadian Consensus Criteria) is associated with decreases in white matter, gray matter and blood volume deficits in the brain as compared to healthy controls.
- 2016, A qEEG/LORETA study of nine controls and nine CFS patients (per DePaul Symptom Questionnaire and Canadian Consensus Criteria definitions), found significantly decreased eLORETA source analysis oscillations in the occipital, parietal, posterior cingulate, and posterior temporal lobes in Alpha and Alpha-2. This research suggests that "disruptions in these regions and networks could be a neurobiological feature of the disorder, representing underlying neural dysfunction."
- 2016, A qEEG/LORETA study of one CFS patient (per DePaul Symptom Questionnaire and Canadian Consensus Criteria definitions), found deregulation of the functional connectivity networks. This may explain the common symptom of perceived cognitive deficits such as slow thinking, difficulty in reading comprehension, reduced learning and memory abilities and an overall feeling of being in a “fog".
