The aims of this study were: 1) To derermine the proportion o f bipolar patients among Seasonal affective disorder(SAD), 2) to delineate the clinical features and demographic factors during manic episodes of patients with SAD and patients with Nonseasonal affective disorder(NSAD) and 3) to elucidate the seasonal patterns in births and admissions for mania. The 82 subjects, having had suffered relapses for at least two episodes in two consecutive years, were selected from 375 patients with affective disorder who had been admitted to the Department of Neuropsychiatry of Kyung Hee University Hospital during the 10 years, from 1 January 1980 to 31 December 1989. This study was done by review of psychiatric records, making a comparison between bipolar disorder-SAD(BP-SAD) ( N = 28) and Bipolar disorder-NSAD (BP-NSAD) ( N = 31). This two major categories were subsequently divided into four diagnostic subtypes, namely, BP-SAD without depression(BP-SAD-D), BP-NSAD with depression(BP-NSAD+ D ) and BP-NSAD without depression(BP-NSAD-D). They were analyzed according to sex, birth place, marital state at onset, education, occupation, religion, socio-economic status, premorbid personality, family history of psychaitric illness, mode of initial episode, manic symptoms, current age, age at onset, length of admission, duration of illness and No. of admission. The results can be summerized as the followings : 1) The proportion of BP-SAD in this study was 66.7%. 2) There were significant differences in sex and mode of initial episode between BP-SAD and BP-NSAD(p<0.05). 3) There were significant differences in birth place, religion, mode of initial episode and No. of admission between BP-SAD+D, BP - NSAD + Dand BP-NSADᅳD(p<0.05). 4) There were no significant differences in seasonal patterns of births and admissions for mania. In summary, the present study provides some significant differences in the clinical features and dermographic factors between BP-SAD and BP-NSAD. Further studies are required to clarify the differences between BP-SAD and BP-NSAD.
