Persistent Depressive Disorder (PDD), also known as Dysthymia, is a mild form of depression that occurs long term. Symptoms of PDD can include feelings of hopelessness, low self-esteem, loss of interest, avoidance, irritability, sleep changes, a lack of appetite, and trouble concentrating. PDD often appears during childhood or adolescence and may vary in severity over time.

Misconception vs. Reality

“People with PDD are often perceived as “always sad.”  “

While the requirement for a diagnosis of PDD is a two year minimum depressive state, people who suffer from the disorder will experience both good and bad days. Those with PDD are not “miserable” at all times. 

“PDD is easy to diagnose.”

PDD is relatively hard to diagnose, as it requires a continues depressive state of at least two years and is frequently mistaken for major depressive disorder (MDD). Although people with PDD are able to function rather well in their daily lives, they are often unable to reach their optimum performance.

“PDD is not related to other physical health conditions.”

 PDD typically occurs in the presence of another disorder. Some of the most frequently co-existing disorders include major depressive disorder (MDD), substance use disorders, and personality disorders (including BPD).

“PDD is not as serious as other illnesses, as it is only a mild type of depression.”

Without treatment, PDD can further develop and may become as severe as major depressive disorder (MDD). To help prevent the formation or advancement of thoughts of suicide or self harm, lack of motivation, and chronic lethargy, it is best that those stuggling seek presfessional treatment.
