Who is Affected by Bipolar Disorder?
Bipolar disorder affects approximately 5.7 million adult Americans, or about 2.6% of the U.S. population age 18 and older every year. (National Institute of Mental Health)
The median age of onset for bipolar disorder is 25 years (National Institue of Mental Health), although the illness can start in early childhood or as late as the 40’s and 50’s.
An equal number of men and women develop bipolar illness and it is found in all ages, races, ethnic groups and social classes.
More than two-thirds of people with bipolar disorder have at least one close relative with the illness or with unipolar major depression, indicating that the disease has a heritable component. (National Institute of Mental Health)
