Seasonal affective disorder with summer depression and winter hypomania
TA Wehr, DA Sack and NE Rosenthal
Clinical Psychobiology Branch, NIMH, Bethesda, MD 20892.
The authors describe 12 patients who regularly became depressed in summer.
This pattern is opposite to one the authors previously described, in which
patients became depressed in winter and responded to treatment with light.
Temperature may influence some summer depressions.
