Almost 95 percent of college counseling centers report an increase in the past few years in the number of students who have taken psychiatric medication when they arrive at college. And experts say the college years, ages 18-22, are a common time for those with a mental illness to experience their first bout with depression or first schizophrenic break. Colleges across the country also are reporting an increase in the intensity of mental problems, including depression, stress and self-injury. Experts say reasons for the increased severity of mental illness are mounting academic and parental pressure and the rising financial burden of attending college. Antidepressants are the most commonly prescribed medications on college campuses, and suicide is the second-leading cause of death for college students, following accidents.
