[Approaches to neuropsychiatry as a transition in the separation of neurology and psychiatry].

The focus of the article is on the separation of neurology and psychiatry and their interconnection by means of the discipline of neuropsychiatry. First, the oppositions of "Structure versus Functions" and "Localization versus Holism" are worked out as the main reasons for the separation of neurology and psychiatry. This is followed by the demonstration of the recent developments of "biological psychiatry", "behavioral neurology" and "neuropsychology" which try to bridge the gulf between neurology and psychiatry. Their inadequacies with regard to a real bridge between the two disciplines, which takes account for both sides, is shown. Consecutively, a specific neuropsychiatric conception as a functional dynamic one, is suggested, which can be distinguished from the approaches in "biological psychiatry" and "behavioral neurology". This neuropsychiatric conception is applied, in a last step, to the oppositions of "Structure versus Function" and "Localization versus Holism", by means of which these oppositions, and the one between neurology and psychiatry, can be bridged--this is exemplified by means of the Parkinson-Syndrome with its neurologic and psychiatric symptoms.
