Some results of the epidemiological studies on schizophrenia conducted recently by the Epidemiology Department of the Psychiatry Institute, the USSR Academy of Medical Sciences, are summed up. The principal demographic data on schizophrenia, such as its prevalence and forms as well as the pathogenetic role of the sex and age are presented. Taking the paroxysmal forms as a model, the application of the epidemiological method in investigating the course and probable prognosis of schizophrenia is reviewed in greater detail. On the basis of the material from a representative group of patients with paroxysmal schizophrenia of the 15-year duration or over (1461 patients), the basic regularities of the time course of negative and positive disturbances during remission, as well as the specific features of the shift in the clinical forms of paroxysms are demonstrated. Statistical distribution shows that in most patients, the distinctive signs of a given form of the disease course tend to remain unaltered during the whole period of the illness. Apart from reflecting the stability of patterns of the disease course, these findings support the validity of the current schizophrenia differentiation.
苏联医学科学院精神病学研究所流行病学部近期开展的一些关于精神分裂症的流行病学研究结果进行了总结。介绍了精神分裂症的主要人口统计学数据，如患病率、形式以及性别和年龄的致病作用。以发作形式为模型，更详细地回顾了流行病学方法在研究精神分裂症病程和可能预后方面的应用。根据15年及以上病程的发作性精神分裂症患者代表性群体（1461例患者）的资料，展示了缓解期阴性和阳性障碍病程的基本规律，以及发作临床形式转变的具体特征。统计分布表明，在大多数患者中，特定病程形式的独特体征在整个疾病期间往往保持不变。这些发现除了反映病程模式的稳定性外，还支持当前精神分裂症分型的有效性。
