Question

Quizplus · Accepted Answer

Persistent depressive disorder is characterized by symptoms that persist for at least two years, whereas major depression involves symptoms that persist for at least two weeks but usually resolve within a few months. Therefore, the distinction between the two disorders is based on the duration of symptoms. Intensity of symptoms may vary between individuals and does not necessarily distinguish between the two disorders. The inclusion in the DSM-5 is not a sufficient basis for distinguishing between the two disorders as both are included in the manual.
