Depression

What is depression?

Depression (major depressive disorder) is a common and serious medical illness that negatively affects how you feel, the way you think, and how you act. Fortunately, it is treatable. Depression causes feelings of sadness and/or a loss of interest in activities you once enjoyed. It can lead to a variety of emotional and physical problems and can decrease your ability to function at work and at home.

Depression symptoms can vary from mild to severe and can include:

• Feeling sad or having a depressed mood

• Loss of interest or pleasure in activities once enjoyed

• Changes in appetite — weight loss or gain unrelated to dieting

• Trouble sleeping or sleeping too much

• Loss of energy or increased fatigue

• Increase in purposeless physical activity (e.g., inability to sit still, pacing, handwringing) or slowed movements or speech (these actions must be severe enough to be observable by others)

• Feeling worthless or guilty

• Difficulty thinking, concentrating or making decisions

• Thoughts of death or suicide

Depression affects an estimated one in 15 adults (6.7%) in any given year. Depression can occur at any time, but on average, first appears during the late teens to mid-20s. Women are more likely than men to experience depression. Some studies show that one-third of women will experience a major depressive episode in their lifetime.
