Prevalence and Prognosis
Among adults, 15-to-24-year olds are most likely to have had a major depressive episode in the past month.
Depression is less common among children than among adults.
Depression may be most likely to leave psychological and social scars if it occurs initially during childhood, rather than during adulthood
