This study is an attempt to ascertain whether evidence for seasonal variations of the episodes of recurrent affective psychoses can be found in patients in Greece. Due allowance has been made for the fact that different socio-cultural and above all climatological factors prevail in Greece as opposed to other countries, which might be relevant in the phenomenon of seasonality. The seasonal distribution of the psychotic episodes, either depressive or manic, has been examined for 533 patients with various forms of affective psychoses, admitted to and treated in the State Mental Hospital of Athens, Greece, during the last 50 years. Statistically significant seasonal variation with peaks in spring was found for both depressive and manic episodes of various subgroups of patients, divided according to the I.C.D.-9.
本研究旨在确定在希腊的患者中是否能找到复发性情感性精神病发作存在季节性变化的证据。考虑到与其他国家相比，希腊存在不同的社会文化因素，尤其是气候因素，而这些因素可能与季节性现象相关。我们对过去50年里入住希腊雅典国家精神病院并接受治疗的533例患有各种形式情感性精神病的患者的精神病发作（无论是抑郁发作还是躁狂发作）的季节性分布情况进行了研究。根据国际疾病分类第九版（I.C.D.-9）划分的不同亚组患者的抑郁发作和躁狂发作，均发现了具有统计学意义的季节性变化，且在春季达到高峰。
