Persistent Depressive Disorder (Dysthymia) Causes, Symptoms and Treatment

Depressive illnesses include episodes of persistent depressive disorder that range from mild to moderate. For two years or more, the person will probably be sad or depressed most of the time, on most days.

Anyone at any age can suffer from PDD, which is fairly common. Effective treatment relies on a combination of medications, counseling, and lifestyle changes.

What is Persistent Depressive Disorder?

Persistent depressive disorder (dysthymia) is a form of depressive disorder that describes a condition of extreme sadness over a long period. The diagnosis is relatively new and is a combination of chronic major depressive disorder and dysthymia.

Although dysthymia is not as serious as major depression, it tends to last longer.  PDD triggers feelings of despair and deep sadness that last for an extended period. You may experience these feelings both psychologically as well as physically, including sleep and appetite.

Therefore, people with the disorder usually lose interest in daily activities and find it difficult to complete daily tasks. People who suffer from persistent depression say they have been depressed ever since they were young, or they feel they go in and out of depression constantly.

Persistent depressive disorder symptoms are similar to major depression. However, PDD symptoms are often milder and last longer. These kinds of illnesses can linger for a long time, interfering with academics, work, and relationships.

It is also harder to manage the symptoms of PDD because they are chronic so it can be challenging. However, patients will benefit from a combination treatment of medication and talk therapy that can be very effective for the treatment of PDD.

Persistent Depressive Disorder Symptoms

The symptoms of PDD are the same as those of depression. A persistent low mood or sad mood is the main symptom of persistent depressive disorder. People suffering from persistent depressive disorders may also be irritable.

PDD, however, is chronic, with symptoms affecting a significant number of people for at least two years. Here are some other PDD symptoms:

  • Weight gain or loss
  • Sleep deprivation or too much sleep
  • Difficulty concentrating

The symptoms of PDD generally begin in childhood or adolescence. The PDD child or adolescent shows signs of becoming pessimistic, irritable, moody, etc. for an extended period.

A primary care professional may be able to recognize depression in a patient and may refer you to a mental health professional for a full evaluation. When a person is suffering from depression for more than two years, clinicians diagnose it as persistent depression.

Initially, your doctor will conduct a physical examination to diagnose accurately. Other tests such as blood tests or laboratory tests may be performed by your doctor to rule out any medical conditions that may be causing your symptoms.

Whenever your symptoms aren’t explained by any physical explanation, your doctor may suspect that you are suffering from a mental health illness. You will be asked several questions by the doctor to assess your current emotional and mental state.

When discussing your symptoms with your doctor, be truthful. If you respond accurately, the doctor will diagnose whether you have PDD or another mental illness.

Many PDD cases are diagnosed using DSM-5 symptoms. The American Psychiatric Association published this manual.

A DSM-5 list of PDD symptoms includes:

  • An almost constant state of depression for most of the day
  • Overeating or having a poor appetite
  • Insomnia or stay asleep
  • Weakness or fatigue
  • Poor self-esteem
  • Difficult to make decisions because of poor concentration.
  • Hopelessness

An adult must suffer from depression for at least two years to be diagnosed. Children or teens must experience depressive feelings or excessive irritability most days of the week for at least one year before they will be diagnosed with the disorder.

There is no need to wait two years before getting treatment! People with symptoms for four months or less can still receive treatment for persistent or distressing symptoms.

Most doctors who believe you have PDD will recommend that you seek mental health treatment.

Persistent Depressive Disorder Treatment

Medications and therapy are used for the treatment of PDD. Talk therapy is thought to be less effective than medication when used alone. In many cases, the best course of treatment is a combination of medications and talk therapy.

Medications

The following types of antidepressants can treat PDD:

  • Sertraline (Zoloft) and fluoxetine (Prozac) are SSRIs, which inhibit serotonin reuptake
  • Asendin (amitriptyline) and Elavil (amitriptyline) are tricyclic antidepressants
  • Desvenlafaxine (Pristiq) and duloxetine (Cymbalta) are SNRIs, which inhibit norepinephrine and serotonin reuptake

It may be necessary to try various medications and dosages before you find an effective treatment. The medication has to take effect for several weeks, so patience is required.

If you are concerned about your medication, talk to your doctor. Depending on your medical condition, your doctor may recommend changing dosage or medication.

Consult your doctor before stopping a medication without first talking to them. Withdrawal-like symptoms can occur if you suddenly stop your medication or miss several doses. Depressive symptoms may worsen.

Talk Therapy

Many people with PDD benefit from talk therapy. The benefits of counseling include:

  • Be open to your feelings and thoughts
  • Managing your emotions
  • Adapt to a crisis or a life challenge
  • Understand the feelings, thoughts, and behaviors that aggravate symptoms
  • Make positive changes to negative beliefs
  • Get a sense of control over your life and gain satisfaction
  • Be realistic with your goals

The process of talk therapy can be done privately or in a group. Support groups provide a safe environment where people who experience similar problems can share their feelings.

Lifestyle Changes

You should participate actively in your treatment plan as PDD is a long-term condition. Some lifestyle changes can complement medicine and ease symptoms.

There are several remedies, including:

  • Exercise daily
  • Each rich food, such as fruits and vegetables
  • Avoid alcohol and drugs
  • Seeing an acupuncturist
  • Take certain supplements such as fish oil and St. John’s wort
  • Practicing tai chi, yoga, or meditation
  • Write daily, what’s on your mind

When to Call a Professional

If you or a loved one is suffering from this disorder, you should consult a health care professional.

Hopes for recovery

An individual suffering from this disorder has an excellent outlook on treatment. There is often a significant reduction in the intensity and duration of symptoms. Many people completely recover from these symptoms.

A person without treatment is more likely to suffer from the illness for a longer period, suffer a decreased quality of life and develop major depression in the future.

Symptoms often return even after successful treatment. To prevent this, maintenance treatment is prescribed.
