[Psychopathologic syndromes in alcoholic intoxication, drug abuse and cerebral ischemia].

The triadic system of psychiatry according to Kurt Schneider (1887-1967) is considered the systematic framework. The main forms of alcoholic poisoning, medication abuse and defective cerebral circulation are examined with regard to the unspecificity of psychopathological syndromes. Despite a considerable convergence there are quite a few differential diagnostic criteria, which are helpful in solving the perioperative problems of alcoholics and persons with medication dependency or defective cerebral circulation. All participants in the treatment of such patients must expand their knowledge of psychopathology and psychiatry.
