Persistent Depressive Disorder (PDD), also known as Dysthymia, is a type of depression that is characterized by a depressed mood that lasts for at least two years. The symptoms of PDD are generally less severe than Major Depressive Disorder (MDD), but they are long-lasting and can significantly impact daily life. Here are some common terms related to Persistent Depressive Disorder:

  1. Anergia: Anergia is a symptom of PDD that refers to a lack of energy or motivation to engage in activities that were once enjoyable.
  2. Cognitive Distortions: Cognitive distortions are negative thoughts and beliefs that can contribute to the development and persistence of PDD. They can include beliefs such as "nothing ever goes right for me" or "I'm a failure."
  3. Double Depression: Double depression refers to the co-occurrence of PDD and MDD. It can be challenging to treat, as the symptoms of both disorders can reinforce each other.
  4. Emotional Numbness: Emotional numbness is a symptom of PDD that refers to a lack of emotional reactivity or response to positive or negative events.
  5. Interpersonal Psychotherapy (IPT): IPT is a type of therapy that is commonly used to treat PDD. It focuses on improving social functioning and communication skills, as well as identifying and addressing negative interpersonal patterns.
  6. Psychotherapy: Psychotherapy is a type of therapy that is commonly used to treat PDD. It involves talking to a mental health professional to explore negative thoughts and feelings and develop coping strategies.
  7. Serotonin and Norepinephrine Reuptake Inhibitors (SNRIs): SNRIs are a type of antidepressant medication that are commonly prescribed to treat PDD. They work by increasing the levels of serotonin and norepinephrine in the brain, which are neurotransmitters that affect mood.

It is important to seek help from a mental health professional if you or someone you know is experiencing symptoms of PDD. While PDD can be challenging to treat, with the right combination of therapies and medications, individuals with PDD can experience significant improvement in their quality of life.
