Bipolar Disorders in the Emergency Department.

Affective disorders affect the way that people think and feel and are classified into unipolar disorders and bipolar disorders. Bipolar disorders represent a spectrum of these chronic mental health illnesses. Patients with bipolar disorder have high recurrence of acute symptoms, and on average spend 20% of their life in exacerbations characterized by mania, depression, or psychosis. Given the increased morbidity and mortality associated with bipolar disorders, it is imperative that the emergency physician remain vigilant when these patients seek emergency care.
