Types of Depression: 15 Common Depressive Disorders

4 Primary Types of Depression

There are many types of depression, but four primary forms are major depressive disorder (MDD), persistent depressive (dysthymia), premenstrual dysphoric disorder (PMDD), and disruptive mood dysregulation disorder (DMDD):

1. Major Depressive Disorder (MDD)

Major depressive disorder (MDD) is the condition many picture when they think of depression. More than 20 million Americans have the condition, making it a common form.¹ MDD will affect a person’s mood and happiness, but it also has the power to disrupt a person’s energy, sleep, and diet. MDD can negatively influence the attention levels, concentration, decision-making, and self-esteem of anyone with the condition.²

One person may have only a single episode of major depression with a few mild depression symptoms. Another person could have recurrent MDD with severe symptoms that trigger feelings of worthlessness, guilt, and suicidal thoughts, illustrating the invaluable point that one person’s depression can vary greatly from another’s.

If someone has five or more of these symptoms for at least two weeks, MDD could be to blame:²

• Feeling sad, low mood, or increased irritability
• Low motivation to engage in pleasurable activities
• Low energy or feelings of fatigue
• Unintentional weight loss or weight gain
• Significant sleep changes – sleeping too much or too little
• Problems with concentration or decision-making skills
• Feeling very slowed down or sped up in thinking or actions
• Feeling worthless or excessively guilty for no reason
• Frequent thoughts about death or suicide

2. Persistent Depressive Disorder (Dysthymia)

People with persistent depressive disorder (dysthymia) will feel periods of depression lasting for two years or longer vs. the two weeks needed for a major depressive episode. Since symptoms of persistent depressive disorder are so long in duration, a person can struggle to remember a time when they weren’t depressed.

It’s possible for a person’s experience with depression to begin with MDD before the condition gives way to the extended duration of persistent depressive disorder.

Like with MDD, symptoms of persistent depressive disorder center around:²

• Poor appetite or overeating
• Sleeping too much or sleeping too little
• Low energy
• Poor self-esteem
• Trouble concentrating and making positive decisions
• Feelings of hopelessness

While other depressive disorders have a way of remitting and returning, the trademark of persistent depressive disorder is the disorder’s consistency. This consistency can frustrate the individual, their family, and even mental health professionals tasked with treating the condition.

Symptoms may show little improvement, even with expert treatment. If signs of persistent depressive disorder do alleviate, they may only do so for less than two months before returning. The disorder, formerly called dysthymia, affects about 0.5% of people in the U.S. each year.

3. Premenstrual Dysphoric Disorder (PMDD)

Premenstrual dysphoric disorder (PMDD) should not be confused for common reactions to menstruation. The hormonal changes linked to menstruation create an expected shift in mood and energy, but premenstrual dysphoric disorder marks an extreme departure in irritability and anxiety disorders brought on by the menstrual cycle.

The symptoms typically build during the days leading up to menstruation and will then alleviate a few days after menstruation begins. Premenstrual dysphoric disorder will create a negative effect on the person’s school, work, or social life due to the intensity of symptoms.

Premenstrual dysphoric disorder affects as many as 5.8% of menstruating women each year. To accurately identify premenstrual dysphoric disorder, experts look for multiple symptoms from several clusters.²

To be diagnosed with PMDD, you must have at least one symptom from the following:

• Increased mood swings, increased sensitivity, or suddenly feeling sad
• Increased irritability and anger, which may impact relationships
• Feeling depressed, hopeless, and negative about self
• Increased anxiety, tension, and feelings of being on edge

And at least one symptom from the following:

• Lower interest in usual activities
• Poor concentration
• Lack of energy and feeling lethargic
• Significant appetite change
• Sleep changes
• Pain, tenderness, or swelling

Symptoms from both categories must equal five or more to achieve the standard for diagnosis. As with other mental health disorders, these symptoms must cause stress and impairment of normal functioning to qualify.

4. Disruptive Mood Dysregulation Disorder (DMDD)

Disruptive mood dysregulation disorder (DMDD) is a condition marked by high levels of irritability. People with DMDD will have frequent outbursts and tantrums that occur at home, work, school, or in the community. In between the outbursts, they will display a chronically irritable mood.

DMDD marks a major deviation from how most people think about depression. Here, the person is not presenting with sadness, low energy, and hypersomnia. With DMDD, the person will seem angry, aggressive towards people and property, and frustrated with self and others.²

Someone with DMDD will display symptoms, including:²

• Severe and repeated temper outbursts that are too extreme for the situation
• The outbursts are inappropriate for the person’s age and developmental levels
• The tantrums occur at least three times each week
• Mood is steadily irritable in between outbursts

An essential aspect of DMDD is the timing of the symptoms as mental health professionals cannot give the diagnosis to anyone under six and older than 18. Experts believe that between 2% and 5% of people under 18 will have DMDD each year.

Kids with DMDD may grow up to have no mental health disorders, while others may experience depressive or anxiety disorders as adults. The good news is children with DMDD do not usually become adults with bipolar disorder.¹

Other Common Depressive Disorders

The above conditions will be the most frequently encountered depressive disorders, but there are others, including substance-induced depressive disorder and smiling depression.

Other depressive disorders include:²

• Substance/medication-induced depressive disorder: This occurs when the use of drugs, alcohol, or medications cause depressive symptoms to emerge. This diagnosis may be given to a person experiencing depressive symptoms for the first time in the weeks and months that follow recovery from opioid dependence.
• Depressive disorder due to another medical condition: A group of depressive symptoms triggered by a medical condition, physical health change, or an event like a stroke. People may experience new or worsening depression following a heart attack, and this diagnosis could be the most appropriate fit.
• Smiling depression: Smiling depression is when an individual appears happy but is actually depressed
• Other specified depressive disorder & unspecified depressive disorder: When depressive symptoms appear but do not fit into other categories, one of these diagnoses, or depression nos (not otherwise specified) could be appropriate. For example, someone may have four intense symptoms of a major depressive episode, but since the condition requires five, they would not qualify.
• Melancholic depression: A type of depression that has a primary symptom of melancholia. It can appear as though someone with this depression is moving slower both physically and cognitively.
• Existential depression: A type of depression that is based on feeling purposeless and aimless about life in times of pain or distress.
• Double depression: A combination of depression types such as persistent depressive disorder and major depressive disorder.
• Agitated depression: Depression symptoms that center around feelings of anxiety and low mood.
• Walking depression: A type of depression where the individual appears to function well in life.

Other Specifiers for Depression

While the disorders listed above are some of the most common, depression can take on many forms with symptoms that serve to further complicate the individual’s experience. People will endure other types of depressive disorders and depression specifiers that add another layer of complications.

With depressive disorders, the American Psychiatric Association (APA) lists eight specifiers. The presence of one or more of these can drastically modify the timing, intensity, and types of symptoms expressed by depression. These specifiers aren’t separate types of depressive disorders. They are additional labels experts insert onto the diagnosis.¹

The specifiers for depressive disorders, according to the APA, include:¹

Peripartum Depression

Postpartum depression is a term used often in the media and popular culture to describe depression that emerges or worsens in the days and weeks after a woman gives birth. Despite its popularity and familiarity as a mental health diagnosis, the accepted term is depression with peripartum onset.¹

The distinction between postpartum and peripartum is important because as many as 50% of women experience the increase in depression before the baby is born. Using the appropriate name can help bring more attention and normalcy to the condition that affects between 3 and 6% of women.¹

Some periods of sadness and anxiety are common in the weeks that follow birth, but just as premenstrual dysphoric disorder is significantly different from typical menstruation, depression with peripartum onset is significantly different from “the baby blues.”

Women can experience a range of intense and potentially dangerous symptoms including:^1,3

• Severe anxiety
• Panic attacks
• Hallucinations
• Delusional or paranoid thoughts
• A desire to harm self or the baby

Diagnosing depression with peripartum onset is valuable because a woman with the condition has about a 50% chance of similar symptoms repeating during or after the following pregnancies. Learning about and treating the condition can help mothers make informed decisions in the future.¹

Seasonal Affective Disorder (SAD)

Seasonal affective disorder (SAD) is not an officially-recognized disorder, but it is one that many people are familiar with through its use in media and culture. The preferred term among mental health professionals is depression with seasonal onset or bipolar disorder with seasonal onset.¹

Feeling down, lethargic, or poor motivation during the fall and winter is a perfectly natural response to changing weather patterns, but some people note symptoms that exist beyond the average person. These people could be experiencing depression with seasonal onset.

When a person has symptoms of seasonal onset, they will experience the standard symptoms of depression linked to major depressive disorder only during a certain season or part of the year. To have seasonal onset, there must be no depressive episodes during the other parts of the year.

Though some may have SAD symptoms during the summer and spring, most will experience symptoms in the fall and winter as the shorter daylight hours impact hormones, neurotransmitters, and circadian rhythms of the body.⁴ Fortunately, there are many tips for dealing with seasonal affective disorder.

Catatonic Depression

Depression commonly reduces a person’s energy and motivation, but when a person has major depressive disorder with catatonia, drastic changes to speech, movement, and response to stimuli occur. Catatonic depression is an extreme form of depression that can cause tremendous concern to loved ones.

Catatonia has two main subtypes that differ in the symptoms produced:⁵

• Stuporous catatonia: is marked by slowed movements and responses. A person with this form could lack speech and spontaneous movement. They may become completely obedient and respond to any request.
• Excited catatonia: is marked by sped up, bold, and erratic movements. Pressured speech is going to be scattered and disorganized.

Symptoms of depression with catatonia can confuse even seasoned mental health experts, but fortunately, these serious symptoms will only present during periods of depression. By managing depression, a person can successfully manage catatonia.

Psychotic Depression

Another form of depression that deviates from the common perception of the condition is psychotic depression. Officially labeled as depression with psychotic features, this form of depression can be quite severe and result in the individual experiencing various hallucinations or delusions.¹

During periods of psychosis linked to depression a person may experience depressive symptoms as well as seeing, hearing, smelling, and feeling things that are not really present. The delusions may involve extreme paranoia, feelings that they are in danger, concerns that others are reading their minds, or the notion that they have powerful romantic connections with those they have never met.¹

People experiencing depression with psychotic features will not have schizophrenia or another psychotic disorder because these symptoms only emerge when depressive symptoms are intense. Still, they could pose a great danger to self or others, and should receive emergency treatment when needed.

Other Forms of Depression Without a Diagnosis

Because depression varies so much from person to person, the symptoms and experiences of some people will not have a diagnosis that seems to be the appropriate fit. A professional may offer a MDD or unspecified depressive disorder diagnosis, but these cannot capture the individual’s status, so some “unofficial” terms can prove helpful.

High-Functioning Depression

Sometimes, a person’s depression is obvious as their nonverbal and verbal cues seem to convey their state. With key signs of high-functioning depression, the opposite is true as their presentation may mask the reality of their symptoms.

People with high-functioning depression can experience low mood, sadness, low energy, low motivation, and poor self-worth, but they conceal their symptoms. On the outside, they appear to be a fully-functional part of society who works, raises kids, and even participates in community activities, all while battling the unwanted, behind-the-scenes effects of depression.⁶

Reactive Depression

Reactive depression has symptoms that seem to stem from the outside vs. the inside (i.e., endogenous & exogenous depression). Many people may feel the impact of depression caused by negative views of their self-worth or physical appearance, but those with reactive depression experience numerous symptoms triggered by the outside world.⁷

When world events turn ugly, the national political landscape shifts negatively, or issues in the home escalate, a person with reactive depression will be impacted in a particularly powerful way. Reactive depression can become a significant distraction as the individual will focus more effort and energy on the outside vs. addressing and tending to their needs.

When & Where to Get Help for Depression

People looking for how to treat depression may worry that it’s too early to contact a mental health professional as they hope the symptoms will resolve with time. However, there’s no such thing as getting help for depression too early. If symptoms of depression, or any other mental health concern, begin to emerge, seek professional guidance

Here are examples of where someone might find depression treatment:

• Mental health services coordinated from their work or school
• Counseling at their primary care office
• In-person, traditional therapy services
• Online, telephone, text, or app-based counseling

Types of Depression Treatment

Treatment may include a combination of medication for depression, psychotherapy, and lifestyle changes. Medication takes time to alleviate symptoms, so it’s important to also discuss options with your prescribing doctor.

How to Find a Therapist

You can find a therapist for depression issues by searching an online therapist directory or by asking for a referral from your primary care provider. All licensed therapists are equipped to help people struggling with mental health issues such as depression and should have formal training in treating this issue. Reading reviews and looking at clinician bios to understand the scope of their practice can give you an idea of whether their experience suits your situation. Many therapists offer a free phone consultation to help you know if you’ll be a good fit.

If you’re ready to begin online therapy, Talkspace is an excellent choice for those with insurance. If you do not have insurance, there are several online therapy options to choose from, with one of the most accessible options being BetterHelp.

Final Thoughts on Types of Depression

No one should tolerate depression. Whatever type of depression you may be dealing with, you are not alone, no matter how you feel. Talk to trusted supporters in your life and consider reaching out to a therapist sooner rather than later. It is a small decision that could have a huge impact on your life and well-being.
