Psychiatry is Neurology: White matter pathology permeates psychiatric disorders

In conclusion, psychiatric disorders, usually referred to as “mental illnesses,” are unquestionably neurologic disorders. Similarly, all neurologic disorders are associated with psychiatric manifestations. WM pathology is only 1 of numerous structural brain abnormalities that have been documented across psychiatric disorders, which proves that psychiatry is a clinical neuroscience, just like neurology. I strongly advocate that psychiatry and neurology reunite into a single medical specialty. Both focus on disorders of brain structure and/or function, and these disorders also share much more than WM pathology.²⁹
