What causes bipolar disorder?

Bipolar disorder can be caused by many different factors including your genetics, your environment, and imbalances in chemicals in your brain that regulate mood. Before you are diagnosed with bipolar disorder, your doctor will ask you questions to try to determine what factors may have contributed to developing bipolar disorder. Ultimately, it is impossible to pinpoint exactly what caused it or why, however a thorough history taken by your doctor can help you and them understand better.
