(September 2, 2008 - Insidermedicine) From Stockholm - According to research in the Archives of General Psychiatry, having an older father may raise the risk for bipolar disorder.

From Toronto - According to research in the Archives of General Psychiatry, PET scans have shown that low levels of serotonin are linked to seasonal depressive disorder. In a study of 88 healthy individuals, serotonin uptake binding potential, detected by PET scanning, was significantly higher in the winter, when compared to scans done in the summer. Serotonin is a neurotransmitter that is important in regulating mood.
