Forty-six subjects with bipolar disorder and their relatives and friends
were interviewed in depth about life events preceding the first and the
latest episode of the subject's affective illness. Twenty years of age was
the cutting point for dividing the sample into early- and late-onset
groups. The late-onset group reported the occurrence of significantly more
stressful life events before the first and before the latest episode of
affective illness than the early-onset group did.Abstract Teaser
