The author reports on 7 patients with a primary diagnosis of manic-depressive psychosis who had brief but well-defined episodes of paranoid symptomatology. These episodes apparently represent alterations of psychic defense structure during the dynamic flow of the psychosis toward recovery. In manic-depressive psychosis, with its genetic and physiologic components, the paranoid episodes reaffirm the unitary nature of humans, in whom heredity and physical and psychological factors inextricably interact.
作者报告了7例初步诊断为躁郁症精神病的患者，他们有短暂但明确的偏执症状发作。这些发作显然代表了精神病向康复动态发展过程中心理防御结构的改变。在具有遗传和生理成分的躁郁症精神病中，偏执发作再次证实了人类的统一性，在人类身上，遗传、生理和心理因素相互交织、密不可分。
