“…A seasonal peak in distribution of manic episodes in the spring is a generally accepted view. Although some studies have not confirmed seasonal differences in the occurrence of manic episodes (50–52) or reported a fall peak (53), others have reported peaks during summer months (25, 54–58) or spring (59–63), with a few reporting major peaks in the spring and minor peaks in the fall (64–66). Few studies have specifically separated mixed and non‐mixed episodes.…”

Issues surrounding diagnostic subtyping of manic states remain complex and the debates surrounding categorical versus dimensional approaches continue. To the extent that categorical approaches for mixed mania diagnosis are adopted, both DSM-IV and ICD-10 are too rigid. Inclusion of non-specific symptoms in definitions of mixed mania, such as psychomotor agitation, does not facilitate and may hinder the diagnostic separation of pure and mixed mania. The inclusion of a diagnostic seasonal specifier for DSM-IV, which is currently based on seasonal patterns for depression might be expanded to include seasonal patterns for mania. Boundaries between subtypes may be 'fuzzy' rather than crisp, and graded approaches could be considered. With the continued development of new tools, such as imaging and genetics, alternative approaches to diagnosis other than the purely symptom-centric paradigms might be considered.

“…Leuthold [67] , Frangos et al [68] , Carney et al [69] and Kamo et al [70] reported major peaks in the spring and minor peaks in the fall, while McCartney [71] reported a higher frequency in the fall. Overall, the most consistent findings are a relative decrease in manic episodes during winter months and a peak in the spring, with inconsistent reports of a second minor fall peak or a peak extending through summer.…”

There is general agreement that DSM-IV and ICD-10 require major improvements in format and content to make them more valid, evidence-based and clinically useful. DSM-IV-TR currently includes a series of clinical features that provide potentially useful information on cross-sectional and longitudinal courses of bipolar disorder. This conceptual and data-driven review proposes changes in the current classification by removing, modifying and adding bipolar episode and course specifiers in DSM-V. Specifiers to be maintained would be ‘with catatonic features’, ‘with melancholic features’, ‘with atypical features’ and ‘with rapid cycling’. The ‘seasonal pattern’ modifier should be amended to allow manic, hypomanic and mixed episodes to be included in the description. Some specifiers should likely be substantially reconceptualized (‘severity/psychosis/remission’) or removed (‘with post-partum onset’). Age at onset (early, intermediate or late onset) and predominant polarity (manic, depressive) should be added for their relevance for course and outcome.

“…In 2700BC, Wong T'ai (cited by McCartney, 1962) wrote a thesis which touched on the variation of diseases according to season. Hippocrates is quoted by Zilboorg (1941) as saying 'seasonal climatic conditions are of some importance; manias, melancholias and epileptic disorders he thought of as diseases of the spring'.…”

“…In another German study, Slater (1938) examined the records of 116 cases of manic-depressive illness diagnosed by Kraepelin. He found that hospital admissions peaked in May and to a lesser extent in September. Another personal series, that of McCartney (1962), was of 5678 'neuropsychiatric' cases recorded between 1946 and 1960 in the US. These referrals increased in March, April and May and decreased in June, July and August.…”
