Psychoanalytic Training InstituteMeta-analysis of multiple neuroimagery studies show that there are distinct differences in the brain involvement in disorders identified as neurological versus those identified as psychological.
“Basal ganglia, insula, sensorimotor and temporal cortex showed greater impairment in neurological disorders; whereas cingulate, medial frontal, superior frontal and occipital cortex showed greater impairment in psychiatric disorders. The two classes of disorders affected distinct functional networks. Similarity within classes was higher than between classes; furthermore, similarity within class was higher for neurological than psychiatric disorders. . .From a neuroimaging perspective, neurological and psychiatric disorders represent two distinct classes of disorders.”
