Differences between dysthymia (PDD) and depression (MDD)
Medical professionals typically use PDD to describe a person who experiences clinically significant depression over a long period.

As a result, the most significant difference between the two conditions is how long a person may experience symptoms.

For a diagnosis of MDD, symptoms must last at least 2 weeksTrusted Source, and for a diagnosis of PDD, symptoms must have been present for at least 2 yearsTrusted Source.

The two conditions also differ in terms of recurrence and severity.

While people with PDD will typically experience depression for longer than someone with clinical depression, their symptoms may not be severeTrusted Source enough for an MDD diagnosis. However, people with PDD can still experience major depressive episodes.
