Atypical Depression: Causes, Symptoms and Treatment

Atypical Depression

Atypical depression subtype of dysthymic disorder or major depression involves a variety of symptoms including increased appetite or weight gain, excessive sleepiness, marked fatigue or weakness, moods that are strongly reliant on environmental factors and being extremely sensitive to rejection.

What is atypical depression?

Atypical depression can be either a sign of major depression or dysthymia. When an individual has atypical depression, it is often first experienced in their teenage years.

There are at least five of these nine symptoms in someone suffering from classic major depression:

  • An almost constant state of depression or sadness
  • Inability to enjoy once pleasurable activities
  • Changing weight (loss or gain of more than 5% within a month) or appetite
  • Sleeping excessively or insomnia almost every day
  • Someone who is running down or in a state of restlessness
  • Fatigue or energy loss almost every day
  • Nearly every day, one feels hopeless or worthless or excessively guilty
  • Constantly having trouble concentrating or making decisions
  • Anxiety about dying or suicide, a suicide plan or an attempt at suicide

Dysthymic disorder, now known in the psychiatric community as chronic major depression or “persistent depressive disorder”, adults with major depressive disorder have a depressed mood more than half the time for at least two years (children and adolescents for one year), in addition to at least two of the above-associated symptoms, but not all of the five symptoms characteristic of the illness.

It is very common to suffer from atypical depression, despite its name. A related subtype of depression, melancholic depression, is characterized by insomnia (rather than increased sleep), loss of appetite (rather than increased appetite), a relative lack of mood responsiveness to the environment, and abnormally reduced ability to feel pleasure.

  • Inability to enjoy activities that were once enjoyable

Atypical depression causes

Atypical depression is thought to be caused by dysfunctional brain circuits that regulate mood as well as brain circuits that allow one part of the brain to communicate with another. Signals are sent between nerve cells within these circuits via brain chemicals known as neurotransmitters.

Such chemicals include dopamine, serotonin and norepinephrine. It is believed that antidepressant medicines alter these chemicals and improve the operation of brain circuits related to mood.

Depression has several risk factors. These factors include:

  • Depression in the family
  • Significant losses, such as death, divorce or separation, may potentially trigger depression in individuals (instead of simply normal grief)
  • Feelings of guilt related to interpersonal conflicts
  • Abuse of any kind — physical, sexual or emotional
  • People who are biologically vulnerable to depression who move, change jobs, lose their job, graduate, retire, or become socially isolated should avoid major life changes that can trigger mood disorders
  • Almost any type of serious illness, including cancer, heart disease, stroke or HIV
  • Alcoholism or substance abuse

Atypical depression diagnosis

If you suspect you have MDD with atypical symptoms, schedule an appointment with your doctor. In addition to a physical exam, your doctor may order laboratory tests, like a complete blood count and thyroid function tests.

Your symptoms may be triggered by health problems that can be discovered through these tests. MDD can be relieved by treating an underlying illness.

A psychological evaluation may also be performed by your doctor to check for atypical MDD symptoms. You may be asked about:

  • Symptoms
  • Personal life
  • Past experiences
  • Current medications
  • Personal or family history

When MDD has atypical features, your doctor may diagnose you as:

  • The underlying cause of your symptoms is not a medical condition
  • According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), your symptoms match those listed in that manual

Atypical depression treatment

MDD with atypical features can be treated differently. It is most common for treatment to include a combination of medications, talk therapy and lifestyle changes.


There are many types of antidepressants your doctor can prescribe, such as monoamine oxidase inhibitors (MAOIs) or selective serotonin reuptake inhibitors (SSRIs). Tricyclic antidepressants don’t typically work well on MDD patients with atypical manifestations.

A number of MAOIs and SSRIs have been shown to effectively treat symptoms of bipolar disorder. If the symptoms you are experiencing can’t be controlled with one medication, your doctor can prescribe more than one.

There is a possibility that taking an MAOI will require you to alter your diet. Some antidepressants, such as birth control pills and decongestants, interact with certain foods and medications.

When beginning a new medication, make sure you discuss potential side effects and any food or drug interactions with your doctor.

Side effects of treatment

Atypical depression can be treated with certain medications, some of which have side effects. It is possible to experience side effects such as:

  • Nausea/diarrhea
  • Loss of appetite
  • Headaches
  • Insomnia.
  • Loss of sex drive

Your body usually adjusts to the medication as the side effects subside. Doctors can suggest different types of medication if the side effects do not diminish.


The symptoms of atypical depression can be as severe as those of other types of depression. Every aspect of your life can be affected by atypical depression, including your emotions, behavior, and health.

It is possible for atypical depression to be accompanied by:

  • An increase in appetite leads to weight gain
  • Rejection sensitivity can cause problems in personal and professional relationships
  • Trouble coping leads to drug or alcohol use
  • A mental health disorder such as anxiety may also be present
  • Depression-related suicide
