Size Of The Problem • The World Health Organization ranks major depression among the most burdensome diseases in the world • Approximately 5 to 10 percent of primary care patients meet DSM-IV criteria for major depression, 3 to 5 percent for dysthymia, and 10 percent for minor depression. • About 70%-80% of all psychiatric patients had been firstly visit their Family physician or primary care doctors before seen by psychiatrist. • Depression often Goes Undetected

  4. Prevalence • Depression symptoms are very common. 13 to 20% of the population being affected at any one time. • In KSA the prevalence is similar to that of world wide i.e 20%. • The prevalence of major depression is estimated at 10 to 20 percent in patients with medical illnesses such as diabetes and heart disease. • Women are affected more than men.

  5. Major Depressive Disorder(MDD) • Major depression is a relapsing, remitting illness in most patients. • Recurrence rate is 40% following the first episode over two years. • After two episodes, the risk of recurrence within five years is approximately 75 percent. • 10 to 30 % of patients treated for a major depressive episode will have an incomplete recovery, with persistent symptoms or dysthymia

  6. Depression if untreated or inadequately treated , is a disease associated with high mortality, morbidity and economic costs, and danger serious disorder 15% of the patient commit suicide. • Many patients find a diagnosis of depression difficult to accept

  8. Classification according to DSM IV • Major depressive disorder ( Unipolar). • Dysthymic disorder (mild sepression)- At least 2 years of lower-level depressive symptoms • Bipolar depression - A major depressive episode arises in a patient with a history of hypomanic, manic, or mixed episodes • Adjustmentdisorder - Emotional or behavioral symptoms that arise in response to an identifiable stressor and that cease once the stressor has terminated
