Depressive disorder, frequently referred to simply as depression, is more than just feeling sad or going through a rough patch. It is a mental health condition that requires understanding and care. Left untreated, depression can be devastating for those who have it and their families. Fortunately, with early detection, diagnosis and a treatment plan many people can and do get better.

Some will only experience one depressive episode in a lifetime, but for many, depressive disorder recurs. Without treatment, episodes may last a few months to several years. People of all ages and all racial, ethnic, and socioeconomic backgrounds experience depression.

Depression can present different symptoms, depending on the person. But for most people, depressive disorder changes how they function day-to-day, and typically for more than two weeks. Common symptoms include:

• Changes in sleep
• Changes in appetite
• Lack of concentration
• Loss of energy
• Lack of interest in activities
• Hopelessness or guilty thoughts
• Changes in movement (less activity or agitation)
• Physical aches and pains
• Suicidal thoughts
