According to NAMI , symptoms occur on a spectrum, and the distinction between the types is not always clear-cut. Bipolar II disorder involves periods of hypomania, but depression is often the dominant state.

A person with hypomania may feel good and function well, but their mood will not be stable, and there is a risk that depression will follow. People sometimes think of bipolar II disorder as a milder version. For many, however, it is simply different. As NAMI indicate, people with bipolar II disorder may experience more frequent episodes of depression than people with bipolar I disorder. It involves hypomania and depression, but the changes are less intense. Learn more about the bipolar spectrum.

A medical professional will diagnose bipolar disorder using criteria set out in the DSM The National Institue of Mental Health NIMH explain that in order to receive a diagnosis of bipolar I disorder, a person must have had symptoms for at least 7 days , or less if symptoms were severe enough to need hospitalization. They may also have had a depressive episode lasting at least 2 weeks. To receive a diagnosis of bipolar II, a person will have experienced at least one cycle of hypomania and depression.

The exact cause of bipolar disorder is unknown. However, research suggests that there is no single cause. Instead, a combination of factors may contribute to bipolar disorder. Bipolar disorder often runs in families, and research suggests that this is mostly explained by heredity—people with certain genes are more likely to develop bipolar disorder than others. Many genes are involved, and no one gene can cause the disorder.

But genes are not the only factor. Some studies of identical twins have found that even when one twin develops bipolar disorder, the other twin may not. Although people with a parent or sibling with bipolar disorder are more likely to develop the disorder themselves, most people with a family history of bipolar disorder will not develop the illness.

Researchers are learning that the brain structure and function of people with bipolar disorder may be different from the brain structure and function of people who do not have bipolar disorder or other psychiatric disorders.

Learning about the nature of these brain changes helps doctors better understand bipolar disorder and may in the future help predict which types of treatment will work best for a person with bipolar disorder.

At this time, diagnosis is based on symptoms rather than brain imaging or other diagnostic tests. A psychiatrist or other mental health professional diagnoses bipolar disorder based on the symptoms, lifetime course, and experiences of the individual.

Some people have bipolar disorder for years before it is diagnosed. This may be because:. Treatment helps many people, even those with the most severe forms of bipolar disorder. Doctors treat bipolar disorder with medications, psychotherapy, or a combination of treatments. Certain medications can help control the symptoms of bipolar disorder. Some people may need to try several different medications and work with their doctor before finding the ones that work best.

The most common types of medications that doctors prescribe include mood stabilizers and atypical antipsychotics. Mood stabilizers such as lithium can help prevent mood episodes or reduce their severity when they occur. Lithium also decreases the risk for suicide.

Additional medications that target sleep or anxiety are sometimes added to mood stabilizers as part of a treatment plan. Talk with your doctor or a pharmacist to understand the risks and benefits of each medication. Report any concerns about side effects to your doctor right away. Avoid stopping medication without talking to your doctor first. Psychotherapy can offer support, education, skills, and strategies to people with bipolar disorder and their families.

Researchers continue to study genetics and bipolar disorder, brain function, and symptoms in children and teens who have bipolar disorder, as well as family history in health and behavior.

Clinical research is medical research that involves people like you. People volunteer to participate in carefully conducted investigations that ultimately uncover better ways to treat, prevent, diagnose, and understand human disease.
