How common is bipolar disorder?

Bipolar disorder is a mental illness characterized by periods of elevated mood, energy, and activity (mania or hypomania) alternating with periods of depression. It is a serious illness that can affect a person's ability to work, go to school, and maintain relationships.

Bipolar disorder is relatively common, affecting about 1% of the population in the United States. It is more common in women than in men, and it typically begins in early adulthood.

Bipolar disorder is a complex illness that is caused by a combination of genetic and environmental factors. It is thought to be caused by an imbalance of certain neurotransmitters in the brain, such as dopamine and serotonin.

There is no cure for bipolar disorder, but it can be effectively managed with medication, therapy, and lifestyle changes. With proper treatment, people with bipolar disorder can live full and productive lives.
