Double Depression: Understanding the Complex Relationship between Depression and Dysthymia


Depression is a common mental health disorder that affects millions of people worldwide. It is a mood disorder that is characterized by feelings of sadness, hopelessness, and helplessness. Dysthymia, also known as persistent depressive disorder (PDD), is a chronic form of depression that lasts for two years or more. While depression and dysthymia are two different mental health disorders, they can coexist, resulting in what is known as “double depression.”

What Is Double Depression?

Double depression is a unique combination of major depressive disorder and dysthymia. People with double depression experience longer periods of low mood and more severe symptoms than those with depression alone. In addition to the symptoms of dysthymia, people with double depression can also experience episodes of major depression. The symptoms of double depression can make it challenging to function in daily life, affecting work, school, and relationships.

Symptoms of Double Depression

The symptoms of double depression are similar to those of major depressive disorder and dysthymia. However, they are more severe and can last longer. The symptoms of double depression include:

• Persistent sadness
• Loss of interest in activities
• Fatigue and low energy levels
• Difficulty concentrating
• Hopelessness and helplessness
• Feelings of worthlessness or guilt
• Insomnia or oversleeping
• Appetite changes
• Weight gain or loss
• Suicidal thoughts or attempts
• Feeling as if life is not worth living

Causes of Double Depression

The exact cause of double depression is unknown. However, experts believe that genetics and environment play a role. Some people are more prone to developing depression and dysthymia due to their genes, while environmental factors such as trauma, abuse, and stress can trigger these mental health disorders.

Risk Factors for Double Depression

Several risk factors increase the likelihood of developing double depression, including:

• A family history of depression or dysthymia
• A history of trauma, abuse, or neglect
• Chronic pain or medical conditions
• Substance abuse or addiction
• A previous depressive episode
• Sleep disorders
• Life stressors such as job loss, divorce, or financial struggles
• Low self-esteem or negative thinking patterns

Diagnosing Double Depression

Diagnosing double depression can be challenging, as symptoms can be similar to other mental health disorders. A mental health professional or doctor will conduct an evaluation and assess a person’s symptoms, medical history, and family history. They may also use various screening tools such as the Beck Depression Inventory, Hamilton Depression Rating Scale or the Patient Health Questionnaire-9 (PHQ-9).

Treatment for Double Depression

Treatment for double depression is similar to treatment for depression and dysthymia. It typically involves a combination of medication, therapy and lifestyle changes.


Antidepressants are often used to treat symptoms of depression and dysthymia. The most commonly prescribed antidepressants are selective serotonin reuptake inhibitors (SSRIs), such as Prozac, Zoloft or Celexa, and tricyclic antidepressants (TCAs). These medications work by balancing the levels of neurotransmitters, such as serotonin and norepinephrine, in the brain.


Therapy is an essential component of the treatment of double depression. Cognitive-behavioral therapy (CBT) can help individuals learn new coping strategies and change negative thought patterns. It can also help people with double depression identify and manage triggers that can exacerbate symptoms. Psychodynamic therapy can address underlying emotional issues, particularly if the symptoms are related to unresolved trauma or other issues from childhood.

Lifestyle changes:

Lifestyle changes can be beneficial in managing symptoms of double depression. Exercise has been shown to be particularly helpful in reducing symptoms of depression and dysthymia. Engaging in regular exercise, such as walking, running, or biking, can increase levels of endorphins and other mood-boosting chemicals in the brain. Additionally, getting enough sleep, eating a balanced diet and avoiding alcohol can also be helpful.


Double depression is a complex and challenging mental health disorder that can severely impact a person’s quality of life. It is vital to recognize the symptoms of double depression and seek treatment early on. Medication, therapy and lifestyle changes can all be helpful in managing the symptoms of double depression. If you or someone you know is struggling with double depression, contact a mental health professional for help. Remember, seeking help is the first step towards recovery.

Cognitive-behavioral therapy, interpersonal therapy, and psychodynamic therapy are common forms of talk therapy used to treat this condition.
