difference between major depressive disorder and persistent depressive disorder

Both major and persistent depressive disorders are chronic conditions that create an environment of stress and worry. This stress is not your normal stress that withers away easily but one that degrades peace of mind and interferes with work and relationships. The main difference between major depressive disorder and persistent depressive disorder lies in its intensity, severity, and duration of occurrence. While major depressive disorder has an intense negative impact on the mind, it usually lasts for a short term like for a week or so. When it comes to persistent disorder, it is usually less empowering but long-lasting. 

For example, let’s consider a situation where a student gets a bad grade on an exam. For a few weeks, the student is depressed because of the sadness of the score. After some time, the sadness subsides and the student is happy again. This behavior can be labeled as major depressive disorder. However, with the persistent disorder, the sadness persists and the student is not happy or excited about anything even after recovering from the sad state.
