Neurology and psychiatry.

There has been a long historical relationship between neurology and psychiatry. This relationship has been nurtured by the common interest in the central nervous system and disturbed behavior associated with dysfunctions of the nervous system. This paper reviews the formal relationships between neurology and psychiatry and particularly looks at the behavioral aspects of neurological disease. For the past 10 years, both from a clinical and a theoretical viewpoint, the importance of understanding central nervous system functioning and dysfunctioning has become increasingly apparent to psychiatrists.
