Prevalence and Incidence of Bipolar disorder

Prevalance of Bipolar disorder:

1.2 percent of the population; 2.3 million adult Americans (NIMH) ... see also overview of Bipolar disorder.

Prevalance Rate:

approx 1 in 83 or 1.20% or 3.3 million people in USA [Source statistic for calcuation: "1.2 percent of the population; 2.3 million adult Americans (NIMH)" -- see also general information about data sources]

Ophanet, who are a consortium of European partners, currently defines a condition rare when if affects 1 person per 2,000. They list Bipolar disorder as a "rare disease". More information about Bipolar disorder is available from Orphanet

Prevalance of Bipolar disorder:

It affects approximately 2.3 million adult Americans—about 1.2 percent of the population. (Source: excerpt from Going to Extremes Bipolar Disorder: NIMH) ... More than 2 million American adults,1 or about 1 percent of the population age 18 and older in any given year,2 have bipolar disorder. (Source: excerpt from Bipolar Disorder: NIMH)

Prevelance of Bipolar disorder discussion:

Bipolar Disorder Research at the National Institute of Mental Health: NIMH (Excerpt)

In this study, one percent of adolescents ages 14 to18 were found to have met criteria for bipolar disorder or cyclothymia in their lifetime. (31)   In addition, close to six percent of adolescents in the study had experienced a distinct period of abnormally and persistently elevated, expansive, or irritable mood even though they never met full criteria for bipolar disorder or cyclothymia. Compared to adolescents with a history of major depressive disorder and to a never-mentally-ill group, both the teens with bipolar disorder and those with subclinical symptoms had greater functional impairment and higher rates of co-occurring illnesses (especially anxiety and disruptive behavior disorders), suicide attempts, and mental health services utilization. The study highlights the need for improved recognition, treatment, and prevention of even the milder and subclinical cases of bipolar disorder in adolescence.

    About prevalence and incidence statistics:

    The term 'prevalence' of Bipolar disorder usually refers to the estimated population of people who are managing Bipolar disorder at any given time. The term 'incidence' of Bipolar disorder refers to the annual diagnosis rate, or the number of new cases of Bipolar disorder diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
