The role of genetic factors in the etiology of seasonality and seasonal affective disorder: an evolutionary approach.

Medical hypotheses - 1 May 2000

Abstract excerpt

The degree to which seasonal changes affect mood, energy, sleep, appetite, food preference, or the wish to socialize with other people has been called seasonality. Seasonal affective disorder (SAD), a condition where depressions in fall and winter alternate with non-depressed periods in spring and summer, is the most marked form of seasonality. Several lines of evidence suggest that genetic factors play an...
