By David Joel Miller.
What if you don’t ever remember being happy?
Persistent Depressive Disorder – PDD (F34.1) is new to the DSM-5. The DSM is the book professionals use to identify mental illnesses. This diagnosis is the result of merging Dysthymia and another group of symptoms which was being researched as Chronic Major Depression. Some other variations on the depressive theme were being called Minor Depressive Disorder, which did not get recognized as such but kind of fits here.
While we may label these conditions as chronic or minor, there is nothing minor about them if you are someone who has this condition?
The defining characteristic of Persistent Depressive Disorder – PDD, is a pervasive sadness that just won’t go away. People who have this condition are always sad or unhappy. They may describe themselves as “always down” or having the blues. While this can cause a lot of impairment, people who have PDD come to think of their chronic sadness as “Just the way I am.”
It is estimated that about two percent of the U. S. population has PDD. Many people with PDD also experience a substance use disorder. There is also an overlap between PDD and Cluster B and Cluster C personality disorders, both of which, to my way of thinking, may have their roots in negative childhood experiences.
Persistent Depressive Disorder (PDD) is more disabling than Major Depressive Disorder.
PDD has been identified on brain scans and seems to affect at least four separate brain regions. PDD is long-lasting, at least two years, often more. During this time someone with PDD may also experience an episode of Major Depressive Disorder. While the major depressive episode may come and go the PDD often remains relatively constant. Because of this constant feature, people with PDD may not be able to ever feel really happy and their functioning, day-to-day, is more impacted than those with Major Depressive Disorder only.
Persistent Depressive Disorder (PDD) is chameleon-like.
Chronic unending depression has a lot of variations. This disorder can exhibit itself a great many ways. As a result, there are eighteen separate specifiers that can and should be added after the F43.1 These specifiers are not exclusive, so one person may also get several specifiers added to the Persistent Depressive Disorder (PDD) diagnosis.
Specifiers include with:
Anxious distress – anxiety commonly co-occurs with depression.
Mood-congruent psychotic features
Mood-incongruent psychotic features
In partial remission
In full remission
Early onset – before 21
Late onset – at or after age 21
Pure dysthymia syndrome
Persistent major depressive episode
Intermittent major depressive episode, currently with MDD
Intermittent major depressive episode, currently without MDD
The symptoms of Persistent Depressive Disorder.
To qualify for PDD a person should have the following symptoms:
- Felt depressed or down, or had others see them this way, most of the day, most days, over a two-year period.
- Had at least two of the following six symptoms. These symptoms should be caused by emotions not by dieting or working long hours, etc.
- Change in appetite either up or down.
- Changes in sleep either too much or too little.
- Felt low in energy or fatigued a lot.
- Low self-esteem.
- Difficulty deciding things or poor concentration.
- Most of the usual exclusions. This has to be causing problems with work, school, relationships, should interfere with important activities or upset the client. It should not overlap Bipolar Disorder or Psychotic Disorder but may overlap Major Depressive Disorder. These symptoms should not be the result of medical or substance use issues.
- These symptoms have been constant and not gone away for two months or more over the required two-year period.
Be careful with the PDD label.
Calling Persistent Depressive Disorder by the label PDD could be problematic. In the past, we had another PDD – Pervasive Developmental Delay which is now recognized as a part of the Autism Spectrum. Persistent Depressive Disorder – PDD is about depression and has nothing to do with Autism. Be careful in reading articles that if they use the label PDD you know which of these two they are talking about. From here on I will call Persistent Depressive Disorder – PDD.
As with the other things we are calling a mental illness this needs to interfere with your ability to work or go to school, your relationships, your enjoyable activities or cause you personal distress. Otherwise, you may have the issues but you will not get the diagnoses if this is a personal characteristic, not a problem. If the only time this happens is when you are under the influence of drugs or medicines or because of some other physical or medical problem these symptoms need to be more than your situation would warrant. These other issues may need treating first, then if you still have symptoms you could get this diagnosis.
FYI These “What is” sometimes “What are” posts are my efforts to explain terms commonly used in Mental Health, Clinical Counseling, Substance Use Disorder Counseling, Psychology, Life Coaching and related disciplines in a plain language way. Many are based on the new DSM-5; some of the older posts were based on the DSM-IV-TR, both published by the APA. For the more technical versions please consult the DSM or other appropriate references.
