Depression is the most common mental disorder, not only for adults, but for children and teenagers as well. The DSM-IV classifies depression as a mood disorder.

In general, older patients whose first episode of depression occurs in late life have a higher relative risk of developing some form of dementia; research suggests that 50% of late-life MDD patients will develop dementia within 5 years. Researchers have considered the pos-sibility that mild cognitive impairment average of 4.3 years.Thirty-six patients with MCI (60%) progressed to AD. Presence of depression at the time of MCI diagnosis did not pre-dict conversion to AD but persistence of depression for 2 to 3 years and the pres-ence of melancholic features were associ-ated with higher risk for AD. Course and prognosis MDD has been characterized as a self-limited disease, with an average duration of 6 to 9 months. However, newer prospective studies suggest that a substantial number of patients recover more slowly or do not ever fully re-cover.Several factors, such as genetic/bio-logic vulnerability and psychosocial factors, influence the courses, prognosis, and risk of relapse/recurrence of MDD in all age groups. The typical duration of a major depressive episode for clinically referred children and adolescents is 8 to 13 months. Approximately 90% of these patients’ major depressive episodes remit by 2 years, but up to 10% persist.Within 5 years of MDD onset, up to 70% of children and adolescents will experience a recurrence,a rate comparable to adults.
