The reason is not entirely clear, but studies have shown that, generally, higher education is often linked with better mental health. Mood disorders such as depression and anxiety affect slightly fewer college students than noncollegiate peers, researchers say.
And the biggest cause of despair? Even among college students, it's not academics, but love that hurts most. Emotional problems were more than twice as common among students who had recently had a major loss -- typically a romantic breakup -- than among those who had not, says Dr. Mark Olfson, the Columbia University psychiatrist who led the research for the National Epidemiologic Survey on Alcohol and Related Conditions.
