- Persistent Sadness: A continuous feeling of sadness or a low mood that lasts for most of the day, more days than not, for at least two years.
- Loss of Interest: A notable loss of interest or pleasure in activities once enjoyed.

- Sleep Disturbances: Insomnia or excessive sleeping.
These symptoms are persistent and can lead to significant impairment in social, occupational, or other important areas of functioning.
Diagnosis of Persistent Depressive Disorder
Diagnosing Persistent Depressive Disorder can be challenging due to its chronic nature and symptom overlap with other mood disorders. A comprehensive evaluation by a mental health professional is essential. This evaluation typically includes:
Clinical Interview
A thorough clinical interview is conducted to assess the symptoms, duration, and impact on daily life. The clinician may inquire about personal and family history of depression or other mental health disorders.
Diagnostic Criteria
According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), PDD is diagnosed when a person experiences a depressed mood for most of the day, for more days than not, for at least two years, along with at least two other symptoms of depression.
ICD-10 Classification
In the International Classification of Diseases (ICD-10), PDD is classified under the code F34.1. This classification aids in the standardization of diagnosis across different healthcare settings.
Causes of Persistent Depressive Disorder
The exact causes of Persistent Depressive Disorder are not entirely understood, but it is believed to result from a combination of genetic, biological, environmental, and psychological factors.
Genetic Factors
Family history plays a significant role in the risk of developing PDD. Individuals with a family history of depression are more likely to experience this disorder.
Biological Factors
Neurotransmitter imbalances, particularly involving serotonin, norepinephrine, and dopamine, are thought to contribute to the development of PDD. Additionally, hormonal changes may also play a role.

Stressful life events, such as trauma, loss of a loved one, or chronic stress, can trigger or exacerbate symptoms of PDD.
Psychological Factors
Personality traits, such as low self-esteem or a pessimistic outlook, can increase the risk of developing Persistent Depressive Disorder.
Treatment Options for Persistent Depressive Disorder
Treating Persistent Depressive Disorder often requires a comprehensive, multi-faceted approach tailored to the individual's needs. Treatment options include:
Psychotherapy
Psychotherapy, or talk therapy, is a cornerstone in the treatment of PDD. Cognitive Behavioral Therapy (CBT) is particularly effective in helping individuals identify and change negative thought patterns and behaviours.
Pharmacotherapy
Medications, such as antidepressants, can be prescribed to help alleviate symptoms. Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are commonly used.
Lifestyle Changes
Incorporating lifestyle changes can significantly improve symptoms. Regular physical activity, a balanced diet, adequate sleep, and stress management techniques can be beneficial.
Support Groups
Engaging in support groups can provide individuals with a sense of community and understanding. Sharing experiences with others facing similar challenges can be therapeutic.
Persistent Depressive Disorder Management
Ongoing management of PDD is crucial to prevent relapse and maintain quality of life. This involves regular follow-ups with healthcare providers, adherence to treatment plans, and being vigilant for any changes in symptoms.
