Depressive disorder
Depressive disorder (also known as depression) is a common mental disorder. It involves a depressed mood or loss of pleasure or interest in activities for long periods. Depression is different from regular mood changes and feelings about everyday life. It can affect all aspects of life, including family, friends, and community relationships. It can result from or lead to problems at school, work, daily functioning, and goal attainment. Depression is one of the most common psychiatric disorders. Approximately 5 % of the U.S. population ages 18 and older experience depression each year. People who have lived through abuse, suffer losses or other stressful events are more likely to develop depression. Women are 50 % more likely to have depression than men. Depression is associated with high mortality and 15 % die by suicide.
