Bipolar disorder is a complex mental health condition marked by shifts in mood, energy, and activity levels that can affect daily functioning. Understanding the different forms of this mood disorder is key to accurate diagnosis, appropriate treatment planning, and long-term symptom management. Here are the main types of bipolar disorder:
Bipolar I Disorder
Bipolar I disorder is defined principally by the presence of manic episodes. To receive this diagnosis, a person must have had at least one manic episode in their lifetime. This episode must last for at least seven days, or the symptoms must be severe enough to require immediate hospital care. While many people with Bipolar I also experience depressive episodes, a depression diagnosis is not required for this category.
Bipolar II Disorder
Bipolar II disorder involves a pattern of depressive episodes and hypomanic episodes. It is separate from Bipolar I, and it is not a milder version of the condition. To be diagnosed with Bipolar II, a person must have experienced at least one major depressive episode and at least one hypomanic episode, but they have never had a full manic episode.
Hypomania is a less severe form of mood elevation compared to the mania seen in Bipolar I. During a hypomanic episode, a person feels distinctively happy or energetic, but the symptoms do not cause major problems in social or work settings. The depressive episodes are often the most challenging part of the condition. These periods involve overwhelming sadness, loss of interest in activities, and low energy.
Cyclothymic Disorder
Cyclothymic disorder, or cyclothymia, is a rarer form of bipolar disorder. It involves a chronically unstable mood state that persists for a long time. People with cyclothymia experience emotional ups and downs, but the symptoms are not as extreme as those in Bipolar I or II disorder. The following characteristics define cyclothymic disorder:
- The symptoms must last for at least two years in adults or one year in children and teenagers.
- The individual experiences many periods of hypomanic symptoms and many periods of depressive symptoms.
- The symptoms are less severe than the criteria required for a major depressive episode or a full manic episode.
- Periods of stable mood (euthymia) usually last for fewer than eight weeks at a time.
Although the symptoms appear milder, this condition still disrupts a person’s life and requires effective management strategies.
Other Bipolar Disorders
Sometimes, a person exhibits clear symptoms of a mood disorder, but these symptoms do not fit the strict diagnostic rules for the types listed above. In these cases, a healthcare provider may diagnose “other specified” or “unspecified” bipolar disorder. This category serves as a catch-all for significant mood changes that do not match the duration or severity criteria of Bipolar I or II.
Several factors can contribute to symptoms falling into this category. The mood swings may be related to a medical condition, such as multiple sclerosis, Cushing’s disease, or a stroke. Treating the underlying medical issue is often the first step in managing these specific symptoms.
Substance use is another factor that doctors contemplate during diagnosis. Certain drugs or alcohol misuse can trigger manic or depressive symptoms that mimic bipolar disorder. A doctor must figure out whether the mood disorder comes from substance use or is a separate issue. This is key to building the right treatment plan.
