Organic Mental Disorders

General Psychopathology
  • Z. J. Lipowski


The current official classification of mental disorders adopted by the American Psychiatric Association in 1980, or DSM-III,1 distinguishes between organic mental disorders (OMD) and organic brain syndromes (OBS). The former term is used to designate a particular OBS whose etiology is known, for example, barbiturate withdrawal delirium or alcohol hallucinosis. “Organic brain syndrome” refers to a set of descriptive characteristics, or psychopathological symptoms and signs, without reference to etiology. This distinction implies that each OBS may be a manifestation of more than one possible etiological factor. If such a factor has been identified in a given case of an OBS, then the term “organic mental disorder” may be used.
