Depression, also called major depressive disorder or clinical depression, is a common mood disorder. It is a complex disorder caused by a combination of genetic, biological, environmental and physiological factors. Commonly known risk factors for depression include chronic pain, major life changes or stressors, certain medications and family history of depression.
Symptoms of depression — such as hopelessness, loss of interest and fatigue — can impact all aspects of a person’s life, including how they think, feel and handle daily activities. Around 80% of adults with depression report at least some difficulty performing work, home or social activities. Depression is a risk factor for attempting suicide.
There are significant societal costs associated with depression. The economic burden of depression in the United States was estimated at $382.4 billion in 2023 dollars, including direct medical costs, loss of workplace productivity and loss of life due to suicide.
According to America’s Health Rankings analysis, populations of adults who have a higher prevalence of depression include:
Depressive disorders are common and treatable. Depression is most commonly treated with psychotherapy, medications or both. Talking with a primary care provider is a common first step to finding mental health care. Additionally, the Substance Abuse and Mental Health Services Administration (SAMHSA) offers an online behavioral treatment locator.
The National Institute of Mental Health provides a guide on how to help someone experiencing emotional pain. In 2022, the 988 Suicide & Crisis Lifeline was launched to provide an easy-to-remember number and 24/7 confidential support for people in distress, as well as prevention and crisis resources, by call, text or online chat. The previous National Suicide Prevention Lifeline number (1-800-273-TALK(8255)) is also active and can still be used.
