What is the difference between depression and clinical depression?

Q: What is the difference between depression and clinical depression?

**Depression vs. Clinical Depression: What's the Difference?** While often used interchangeably, "depression" and "clinical depression" describe different concepts. Depression is a broad term covering a range of mood disorders and low emotional states. Clinical depression, or major depressive disorder (MDD), is a specific medical diagnosis defined by more severe, persistent symptoms—such as prolonged sadness, loss of interest, fatigue, and changes in sleep or appetite—that significantly impair daily functioning for at least two weeks. Understanding which one you may be experiencing is essential, because the right diagnosis leads to the right treatment. If you've been feeling "off" and aren't sure whether it's a passing low mood or something more serious, don't guess—get clarity. Take a free, instant, online symptom check to better understand your symptoms and confidently navigate your next steps toward feeling better. Reviewed for medical accuracy: 07/14/2026
