atypical depressionAbbreviation: AD
A form of depression in which overeating and oversleeping are commonly observed, often but not exclusively in association with leaden paralysis, extreme sensitivity to interpersonal rejection, and highly reactive moods. The condition typically has an earlier age of onset than typical depression, is more likely to affect women than men, and shares some features with bipolar disorder.
