Medically reviewed by Dr. Michael Rodriguez · Editorial Policy
Depression is a common but serious mood disorder that affects how you feel, think, and handle daily activities. According to the National Institute of Mental Health (NIMH), an estimated 21 million adults in the United States had at least one major depressive episode in 2021.
Common Symptoms
Depression symptoms vary but generally include:
- Persistent sad, anxious, or "empty" mood
- Feelings of hopelessness or pessimism
- Irritability, frustration, or restlessness
- Loss of interest or pleasure in hobbies and activities
- Decreased energy or fatigue
- Difficulty concentrating, remembering, or making decisions
- Sleep disturbances (insomnia or sleeping too much)
- Appetite or weight changes
- Thoughts of death or suicide
Symptoms must last at least two weeks and represent a change from previous functioning to be considered a depressive episode.
Risk Factors
- Personal or family history of depression
- Major life changes, trauma, or stress
- Certain medical conditions (thyroid disorders, chronic pain)
- Some medications
- Substance use
When to Seek Help
If you or someone you know is experiencing symptoms of depression, contact a healthcare provider. If there is immediate risk of self-harm, call or text 988 (Suicide & Crisis Lifeline) or call 911.
Treatment is effective for most people. Options include therapy (especially cognitive behavioral therapy), medication, or a combination of both.
