While brain abnormalities in ME\/CFS have been identified, relatively little is known regarding which specific abnormalities are consistently observed across research groups and to what extent the observed abnormalities are reproducible.<\/p>\n<p><strong>Method<\/strong><\/p>\n<p>To identify consistent and inconsistent neuroimaging observations in ME\/CFS, this retrospective and systematic review searched for studies in which neuroimaging was used to investigate brain abnormalities in ME\/CFS in Ovid MEDLINE, PubMed (NCBI), and Scopus from January 1988 to July 2018. A qualitative synthesis of observations was performed to identify brain abnormalities that were consistently and inconsistently reported.<\/p>\n<p><strong>Results<\/strong><\/p>\n<p>63 full-text articles were included in the synthesis of results from 291 identified papers. Additional brain area recruitment for cognitive tasks and abnormalities in the brain stem are frequent observations in 11 and\u00a09 studies using different modalities from different research teams respectively.
