- How does bipolar II disorder differ from bipolar I disorder?
The main difference between bipolar I disorder and bipolar II disorder has to do with the intensity of the manic period.
Bipolar I disorder is characterized by at least one episode of mania before or after a hypomanic or major depressive episode. Sometimes, the manic episodes that occur in bipolar I disorder may trigger a psychotic episode where the person disassociates from reality.
People with bipolar II disorder do not experience true manic episodes, where their mood and energy levels are so high that it causes trouble with work and socializing and may cause psychosis. Some individuals with bipolar I disorder have to be hospitalized during periods of mania.
However, this does not make bipolar II disorder less severe than bipolar I disorder. In bipolar II disorder, the depressive episodes are similar to those in bipolar I disorder and cause significant disruption to the person’s daily life for an extended time.
Symptoms of bipolar II disorder include periods of hypomania followed by depressive episodes.
While it can be normal for people to experience periods of feeling upbeat followed by periods of sadness, in people with bipolar disorder, these swings are more extreme.
People experiencing hypomania may notice a combination of the following symptoms:
- an increase in energy or feeling more agitated
- feeling more upbeat or wired
- increased self-confidence
- decreased need or inability to sleep
- racing thoughts
- talking too fast or talking much more than normal
- a tendency towards reckless behavior, such as spending too much, drinking or using drugs, or risk taking
- impaired decision making
For these periods to be classified as true hypomanic episodes, they must last for at least 4 days and have at least three of the above symptoms.
People experiencing hypomania may feel very good during these periods, and may not know anything is wrong. However, loved ones watching a person with bipolar II disorder will notice abnormal changes in behavior during hypomanic episodes.
When people with bipolar II disorder are not in a hypomanic state, they may be in a major depressive state. Symptoms of major depressive episodes include the following:
- feelings of sadness, emptiness, or hopelessness
- loss of interest in activities
- inability to sleep or sleeping too much
- decreased energy
- feelings of worthlessness and guilt
- trouble concentrating or focusing
- weight gain or weight loss without dieting
- suicidal thoughts or tendencies
Other signs and symptoms of bipolar II disorder may occur during both periods of hypomania and major depressive episodes. These may include the following:
- rapid cycling between states
There are no known risk factors for bipolar II disorders, although some studies suggest there may be a genetic component.
