Bipolar disorder exists on a spectrum, but “partial bipolar disorder” is not a diagnostic term.
Bipolar disorder is a mental health condition involving extreme mood shifts.
Like some other mental health conditions, bipolar disorder exists on a spectrum. There are three common types:
- bipolar I disorder
- bipolar II disorder
- cyclothymic disorder (cyclothymia)
Not every person with bipolar disorder fits neatly into these categories. This can make getting an accurate diagnosis and effective treatment challenging.
People with mild or few symptoms may refer to their condition as “partial bipolar disorder” or “soft bipolar disorder.” These descriptors may be useful to you, but they’re not actual diagnostic terms.
The Diagnostic and Statistical Manual of Mental Disorders, 5th edition, text revision (DSM-5-TR) lists additional terms to account for these types of bipolar disorder:
- other specified bipolar and related disorders
- unspecified bipolar and related disorders
In this article, we go over the symptoms of each type of bipolar disorder and discover how some symptoms may or may not be present.
The moods of bipolar disorder
- Mania is the “high” of bipolar disorder. It can cause feelings of euphoria and intense irritability. You may feel highly energized, reckless, and invincible during an episode of mania. In severe cases, you may need to be hospitalized.
- Hypomania is a milder form of mania. Hypomanic episodes are usually shorter, less intense, and don’t disrupt your life as much as manic episodes. Hospitalization is typically not needed.
- Depression is the “low” of bipolar disorder. You may experience a loss of energy, motivation, and interest in activities you usually enjoy. It may also cause you to sleep too little or too much.
Bipolar disorder presents as a spectrum of conditions. This means the intensity and frequency of symptoms like mania, hypomania, and depression can vary from person to person. Sometimes, the hallmark symptoms may even be absent.
The following are the primary types of bipolar disorder.
Bipolar I disorder
Bipolar I disorder involves manic episodes that last for at least a week at a time.
Mania can affect your sleep patterns. It can also cause you to engage in harmful behaviors or make decisions you wouldn’t typically make. In some instances, severe mania may trigger a psychotic break (a break from reality).
Some people with bipolar I disorder require hospitalization for symptom relief during severe manic episodes.
You can receive a diagnosis of bipolar I disorder with or without depression.
Bipolar II disorder
If your high moods don’t quite meet the criteria for mania, a mental health professional may consider a diagnosis of bipolar II disorder.
Bipolar II disorder involves episodes of hypomania and depression. You may experience extreme and intense depression before or after having a hypomanic episode. People with bipolar II disorder may feel deeply depressed and hopeless for extended periods.
Depression can appear with symptoms such as:
- fatigue
- insomnia
- aches and pains
- suicidal thoughts
Cyclothymic disorder (cyclothymia)
If you have rapid changes in mood but don’t experience extreme highs or lows, you may have cyclothymic disorder.
People with cyclothymic disorder have hypomania and milder depression than those with bipolar I or II disorders. Your shifts in mood may be punctuated by long periods of stability.
Mild depression and hypomania must be present for at least 2 years in adults (or 1 year in children) to get a diagnosis.
Even though it’s milder than bipolar I or II disorders, cyclothymic disorder requires ongoing treatment to manage symptoms. Medical professionals typically treat this condition using psychotherapy and medications, such as mood stabilizers, antidepressants, and antianxiety drugs.
To review what we know so far:
| Mania | Hypomania | Depression | |
|---|---|---|---|
| Bipolar I disorder | ✓ | X | maybe |
| Bipolar II disorder | X | ✓ | ✓ |
| Cyclothymic disorder | X | ✓ | mild |
Other specified or unspecified bipolar and related disorders
According to the National Alliance on Mental Illness (NAMI), other specified and unspecified bipolar and related disorders occur when someone doesn’t meet the criteria for any of the three conditions but still has periods of clinically significant and unusual mood elevation.
Examples include:
- short or mild hypomanic episodes with depression
- hypomania without depression
- cyclothymic disorder that persists for less than 2 years
The treatment for these subtypes is the same as for other forms of bipolar disorder. Your mental health professional may also advise you to make lifestyle changes, such as introducing regular exercise to your routine or eliminating drugs and alcohol.
The DSM-5-TR isn’t the only manual that seeks to define mental health conditions. The
As one
The ICD-11 often refers to bipolar disorder in partial remission. This means your symptoms no longer meet all of the criteria for a manic, hypomanic, or depressive episode, but you still have some symptoms involving your mood or behavior.
You and your mental health professional can discuss the risks or benefits of altering your medication regimen during periods of remission.
To make a diagnosis, a healthcare professional may perform a physical exam and a psychological evaluation. There is no laboratory test to confirm bipolar disorder.
Your psychiatrist or other mental health professional will want to rule out other health conditions. They will also look at the medications you’re currently taking.
Some health conditions and medications can cause symptoms also seen in bipolar disorder, such as depression, anxiety, and irritability. Health conditions with symptoms that mimic bipolar disorder include hyperthyroidism.
During a psychological evaluation, a clinician will ask about:
- your symptom history
- family history of mental health conditions
- your lifestyle habits, such as drug and alcohol use
- whether you have thoughts about suicide
You’ll receive a questionnaire to fill out. This will provide your healthcare professional with information about your symptoms and how they affect your daily life.
If your mental health professional believes you have a type of bipolar disorder, they’ll discuss their findings with you and provide the next steps, including a treatment plan.
Bipolar disorders of all types are chronic (long-term) conditions. While they don’t have a cure, they can be effectively managed. The changes in mood caused by bipolar I and II disorders may occur occasionally or often.
A treatment plan is needed to manage bipolar I and bipolar II disorders. Treatment consists of counseling plus medications, such as antianxiety drugs, mood stabilizers, and antidepressants. Doctors may prescribe antipsychotics to treat bipolar I disorder.
Lifestyle changes, such as eliminating recreational drug and alcohol use, are also beneficial for symptom management.
Bipolar disorder causes symptoms, such as rapid changes in mood and depression, that are also seen with other mental health disorders. Some of the conditions with similar symptoms include:
Can you have bipolar disorder without mania?
Yes. Mania is a hallmark symptom of bipolar disorder, but it doesn’t always need to be present. Bipolar I disorder will always feature mania.
A person with bipolar II disorder may not experience mania but must have experienced at least hypomania (mild manic symptoms).
Can you have bipolar disorder without depression?
Yes. Although most people with bipolar I disorder will likely have symptoms that meet the criteria for depression, it’s not necessary for a diagnosis. The DSM-5-TR defines bipolar I disorder as having mania with or without depression.
A diagnosis of bipolar II disorder requires at least one episode of major depression.
Is bipolar disorder a lifelong condition?
Yes. Bipolar disorder is a chronic (long-term) condition that may include periods of symptom-free or nearly symptom-free remission. There is not currently a cure for bipolar disorder, but symptoms can be effectively managed.
Living with any type of bipolar disorder can cause you to feel exhausted and depressed. It can also cause episodes of high energy or mania. It’s very important to talk with a mental health professional if you have any symptoms of this condition.
Your mental health professional can determine whether you have bipolar disorder or another mental health condition. They can also provide you with treatment that can significantly reduce symptoms.
Beyond your mental health specialist or care team, there are other sources of support. Friends and relatives can be strong support, and several support groups are available.
