title: Newer concepts of psychiatric diagnosis and biochemical research on mental illness.
abstract: Biochemical studies of psychiatric patients have revealed many abnormalities but have failed to identify specific biochemical changes linked to the pathophysiology of the illnesses. Review of these data in the light of newer concepts of psychiatric diagnosis may help to clarify the relationship between biochemical abnormalities and disabilities. These concepts may also suggest useful directions for future research.
