Persistent depression disorder is a chronic form of depression also known as Dysthymia. Persistent depression disorder is recognised as persistent low mood for a period of two years or more. Because this disorder is not acute or severe, the sufferer may believe their symptoms are inevitable or simply part of their character and fail to seek help. It can therefore go unrecognised and undiagnosed,  leaving the sufferer without much needed treatment.

Although the symptoms are classed as mild, this condition can have a significant impact on the life of a sufferer. Because of the feelings of low self esteem, hopelessness and inadequacy that are associated with persistent depression disorder, there can be a negative effect on academic studies, work life and personal relationships.

Persistent depression disorder can affect adults, adolescents and children and is more prevalent in females. It can also occur in conjunction with other mental health issues. It is possible for someone with persistent depression disorder to periodically experience major depressive episodes. This is know as double depression.

If help is not sought, then there is a risk that other complications can arise including other mental health disorders such as major depression, anxiety disorders, substance abuse, family conflicts, reduced quality of life and even suicidal thoughts.


The symptoms of persistent depression disorder resemble those of major depression, but are less severe and develop over time. A person suffering from persistent depression disorder will typically exhibit a depressed mood for the majority of the time, for a period in excess of two years in adults or one year in children.

Associated symptoms can include loss of appetite or a tendency to overeat. The sufferer may experience low energy or extreme fatigue, low self esteem, sleep problems  and poor concentration. As well as a feeling of sadness, the condition can also manifest as irritability, particularly in children or adolescents. This disorder can cause someone to lose interest in their usual activities, to feel hopeless and isolate themselves, socially.

Because of the gradual onset of symptoms, a person may not recognise that they are suffering from persistent depression disorder. It may often require a family member or friend to notice that there is a problem and advise the sufferer to seek help.


Worldwide, it is estimated that persistent depression disorder occurs in approximately 1.5% of the population a year, which equates to around 105 million people. The actual figure could potentially be higher than this because many sufferers may go undiagnosed.


There isn’t one known definitive cause of persistent depression disorder. It’s thought the condition could originate from a number of factors of a genetic, environmental, biochemical or psychological nature.

It has been suggested that a change in serotonin levels could play a part in the onset of the condition. Other recognised triggers could be life events such as life events such as periods of stress, financial difficulties and bereavement.

There hasn’t been a particular method identified for preventing persistent depression disorder but if it is recognised early in a child or adolescent, strategies can be put in place to help stop the symptoms worsening.
