Persistent Depressive Disorder (PDD), previously known as dysthymia, is defined by a chronically low mood that lasts two years or more in adults (one year in children/adolescents). Although symptoms may be less severe than Major Depressive Disorder, their prolonged nature can profoundly impair motivation, self-esteem, and relationships.
Because PDD develops gradually, individuals often normalize their low mood and delay seeking help. Over time, persistent sadness can drain coping reserves and lead to co-occurring conditions such as anxiety, substance misuse, or chronic health issues.
PDD: A Subtle Condition with Serious Impacts
- Millions of people: Approximately 5.2 million adults in the US experience PDD in a given year, many undiagnosed and untreated due to its subtle symptoms
- Eroding effect: Approximately 2.6 million of those adults experience serious impairment from their PDD, including long-term negative behaviors and feelings
Key Symptoms of PDD
A key defining feature of PDD is the duration and consistency of the feelings, not necessarily the severity. Because the patient’s symptoms may not rise to the level of Major Depressive Disorder, which is what many people think of when they hear the word “depression,” PDD is sometimes dismissed by patients and loved ones as a case of “the blues.”
PDD is challenging to self-diagnose or even recognize as a possible issue. Mental health professionals have experience and are trained in PDD diagnosis. If you notice the following symptoms but aren’t sure you need help, a consultation with a professional may provide certainty.
