This paper reports the results of a study on seasonal variation in new episodes of affective disorders, conducted using the South-Verona psychiatric case register. We found evidence for a cyclical pattern in the occurrence of affective psychosis, but this was statistically significant only for the males: there was no cyclical variation in depressive neurosis. The advantages are discussed of case register data over hospital admission statistics for the study of seasonal variation. These are particularly marked in case register areas where community psychiatric care is well developed, as in South-Verona.
本文报告了一项使用南维罗纳精神病病例登记册进行的情感障碍新发病例季节性变化研究的结果。我们发现了情感性精神病发病存在周期性模式的证据，但这仅在男性中具有统计学意义：抑郁性神经症不存在周期性变化。文中讨论了病例登记数据相对于医院入院统计数据在季节性变化研究方面的优势。在社区精神科护理发达的病例登记地区，如南维罗纳，这些优势尤为明显。
