“Geographical predisposition to a mania-predominant course of bipolar disorder in Asia”

- Asian studies report a mania-predominant course of bipolar disorder.
- Manic recurrences more frequent during summer seasons.
- Meteorologically, Asian countries are exposed to prolonged periods of sunshine.
- Greater exposure to sunshine is linked to illness onset and recurrences in bipolar disorder.
- Neurobiological linkage between sunshine exposure and manic-predominance should be explored.
