[Mixed affective disorders].
The Kraepelin concept of "mixed states" has experienced a renaissance over the last two decades. This has been caused by clinical as well as theoretically relevant factors. Of particular clinical relevance is the fact that more than 40% of all patients with bipolar disorders show at least one mixed affective episode during the course of their illness. However, the correct assessment and the precise classification of the symptoms are very important. A diagnosis according to the tight criteria of ICD-10 or DSM-IV, or perhaps based on the moderate Pisa or Cincinnati criteria, is recommended, whereas the use of broader definitions cannot be advised. Mixed schizoaffective episodes are under-diagnosed in comparison to pure affective mixed episodes, although both are defined by ICD-10 as well as by DSM-IV, and the frequency of occurrence is almost the same. Mixed schizoaffective episodes appear to be one of the most severe forms of bipolar disorders. Their clinical relevance is mainly caused by their unfavourable prognosis and difficulty in treatment. Atypical neuroleptics combined with anticonvulsives have proved to be more effective than any other psychopharmacological substances. The occurrence of mixed depressive and manic symptoms during one and the same episode is theoretically important, especially in the sense of their nosological and etiological differentiation.
