Today we’ll be exploring the 3 most common types of mood disorders, outside of depression. Specifically, we’ll be looking at Bipolar Disorders and Cyclothymic Disorder.

What are Mood Disorders?

Bipolar Disorder

Let’s talk about Bipolar Disorder. Bipolar Disorder, previously called manic-depressive disorder, is a mood disorder. It is one of the most commonly misrepresented disorders in the media and the general public. Bipolar Disorder a mood disorder characterized by two opposing types of mood symptoms; hence the name “bi-“ meaning ‘two,’ and “polar,” meaning ‘opposites.’

Bipolar Disorder is not changing your mind quickly, being indecisive, or going from happy to sad in a matter of minutes.

There are actually two types of Bipolar Disorder: Bipolar I Disorder, and Bipolar II Disorder (abbreviated BPD1 & BPD2). Because of the differing mood symptoms, I’ve listed the criteria for specific episodes before going into detail about both types.

Major Depressive Episode

You feel 5 of the following things for at least 2 weeks (must have #1 or #2):

  1. Depressed mood
  2. Loss of interest in previously enjoyable activities
  3. Losing or gaining 5% body weight in a month OR increased/decreased appetite
  4. Either can’t sleep or can’t seem to stop sleeping
  5. Unconscious shaking/trembling or reduced movement
  6. Fatigue or loss of energy almost every day
  7. Feeling worthless or having inappropriate/excessive guilt
  8. Decreased ability to think or concentrate
  9. Ongoing thoughts of death

If you or someone you know is experiencing thoughts of suicide, please contact your local emergency service providers, 911, or call a national hotline such as the National Suicide Prevention Hotline at (800) 273-8255.

In addition, your depressive symptoms cannot be the result of another condition or a substance. Finally, your depressive symptoms have to cause a “clinically significant impairment” (make a noticeable impact) in at least one area of your life, such as school/work/relationships.

Manic Episode

You feel 3 of the following things for at least 1 week:

  1. Inflated self-esteem or feeling more important/impressive (think narcissistic)
  2. Decreased need for sleep (feeling good after 3 hours of sleep)
  3. More talkative or feeling pressured to keep talking
  4. Racing thoughts or flight of ideas (think tornado in your brain)
  5. Easily distracted
  6. Increased energy (like shaking/trembling or writing a novel in a night)
  7. Taking much larger risks (such as spending a lot of money, engaging in risky sexual behaviors, etc.)

With manic episodes, you may experience psychotic symptoms, such as hallucinations or delusions.
Your manic symptoms cannot be the result of another disorder or a substance. In addition, your symptoms must be severe enough to cause a noticeable impact in your daily life.

Hypomanic Episode

You feel 3 of the following things for at least 1 week:

  1. Inflated self-esteem or feeling more important/impressive (think narcissistic)
  2. Decreased need for sleep (feeling good after 3 hours of sleep)
  3. More talkative or feeling pressured to keep talking
  4. Racing thoughts or flight of ideas (think tornado in your brain)
  5. Easily distracted
  6. Increased energy (like shaking/trembling or writing a novel in a night)
  7. Taking much larger risks (such as spending a lot of money, engaging in risky sexual behaviors, etc.)

If you experience psychotic symptoms, you are experiencing a manic episode, not a hypomanic episode.
Your hypomanic symptoms cannot be the result of another disorder or a substance. In addition, your symptoms cannot be severe enough to cause a noticeable impact in your daily life.

Mood Disorder Facts & Stats

Bipolar I Disorder

Bipolar I Disorder requires that you have at least one major depressive episode and one manic episode.
To be diagnosed with Bipolar I Disorder, you only need to have a history of one manic episode. You can experience depressive episodes at every other point in your life and still have Bipolar I Disorder.
Bipolar can also have mixed episodes, where you have symptoms of both depression and mania at the same time. For example, you could feel hopeless and depressed, and still have an excessive amount of energy and take large risks.

Bipolar II Disorder

Bipolar II Disorder requires that you have had at least one major depressive episode, have never had a manic episode, and had at least one hypomanic episode.

Common Misconception: People with Bipolar Disorder do not have Bipolar Disorder AND depression; depression is a part of Bipolar Disorder.

 

Cyclothymic Disorder

Cyclothymic Disorder is sort of like low volume Bipolar Disorder. Previously called cyclothymia, Cyclothymic Disorder states that you have depressive symptoms but don’t meet criteria for a major depressive episode, and that you have hypomanic symptoms but don’t meet the criteria for a hypomanic episode.
This pattern must continue for 2 years before it can be diagnosed.

Cause

Bipolar, like almost every other mental illness, has no known cause. Similar to schizophrenia, Bipolar Disorder has a high genetic factor: you are ten times more likely to have Bipolar Disorder if you have an adult relative with Bipolar I or II.

Time

People with BPD aren’t symptomatic 100% of the time. Some people have very infrequent mood symptoms at all. Other people have many more depressive episodes than manic episodes. And some people have only had one manic episode. It varies dramatically by person.
People with BPD rarely, if ever, go directly from one mood episode to another (manic to depressed or visa versa).
It’s not very predictable.
Most of the time, people are not diagnosed until adulthood because adolescents have a wide range of what is “developmentally appropriate.” This is not to say you cannot be diagnosed before age 18 only that adolescents should be compared to their individual baseline.

Treatment

There are two types of medication prescribed for Bipolar Disorder: antidepressants and mood stabilizers. In some instances, an atypical antipsychotic is prescribed to help manage manic symptoms.
In additional to medications, it can be helpful to be engaged in therapy and support groups. Of all the individuals with mood disorders I have worked with, people with Bipolar Disorder report benefiting the most from support groups.
Exercising and eating well can be a helpful addition.
As always, having a strong, positive support system will make a big difference in your recovery.
