Seasonal relapses in affective disorder in the Tropics: a prospective follow-up of 12 patients.
Seasonal relapses of affective disorder are known. We report 12 patients who had season-linked relapses during a prospective follow-up period of 4 years. There were both winter and summer relapses of mania and depression. The centre is in the tropical zone, with lesser variation of sunshine and temperature than in more extreme latitudes. This may inference the pattern of relapse in affective disorder. Differences in relapses between tropical and temperate zones need to be investigated.
