Bipolar disorder is a brain disorder that causes changes in a person’s mood, energy, and ability to function. People with bipolar disorder experience intense emotional states that typically occur during distinct periods of days to weeks, called mood episodes. These mood episodes are categorized as manic/hypomanic (abnormally happy or irritable mood) or depressive (sad mood). People with bipolar disorder generally have periods of neutral mood as well. When treated, people with bipolar disorder can lead full and productive lives.
People without bipolar disorder experience mood fluctuations as well. However, these mood changes typically last hours rather than days. Also, these changes are not usually accompanied by the extreme degree of behavior change or difficulty with daily routines and social interactions that people with bipolar disorder demonstrate during mood episodes. Bipolar disorder can disrupt a person’s relationships with loved ones and cause difficulty in working or going to school.
Bipolar disorder is a category that includes three different diagnoses: bipolar I, bipolar II, and cyclothymic disorder.
Bipolar disorder commonly runs in families: 80 to 90 percent of individuals with bipolar disorder have a relative with bipolar disorder or depression. Environmental factors such as stress, sleep disruption, and drugs and alcohol may trigger mood episodes in vulnerable people. Though the specific causes of bipolar disorder within the brain are unclear, an imbalance of brain chemicals is believed to lead to dysregulated brain activity. The average age of onset is 25 years old.
People with bipolar I disorder frequently have other mental disorders such as anxiety disorders, substance use disorders, and/or attention-deficit/hyperactivity disorder (ADHD). The risk of suicide is significantly higher among people with bipolar I disorder than among the general population.
Bipolar II Disorder
A diagnosis of bipolar II disorder requires someone to have at least one major depressive episode and at least one hypomanic episode. People return to their usual functioning between episodes. People with bipolar II disorder often first seek treatment as a result of their first depressive episode, since hypomanic episodes often feel pleasurable and can even increase performance at work or school.
People with bipolar II disorder frequently have other mental illnesses such as anxiety disorder or substance use disorder, the latter of which can exacerbate symptoms of depression or hypomania.
Treatment:
Treatments for bipolar II are similar to those for bipolar I: medication and psychotherapy. The most commonly used medications are mood stabilizers and antidepressants, depending on the specific symptoms. If depressive symptoms are severe and medication is not effective, ECT (see above) may be used. Each person’s treatment is individualized.
