[Epidemiology of bipolar disorders. Current studies]

Area of Science:

• Psychiatry
• Epidemiology

Context:

• Bipolar disorder is a chronic mental health condition with a lifetime prevalence of about 1% globally.
• Morbidity rates in institutionalized populations closely mirror general population estimates.
• The disorder affects all demographic groups equally, irrespective of ethnicity, culture, or socioeconomic status.

Purpose:

• To summarize the epidemiological characteristics of bipolar disorder.
• To highlight key demographic and correlational factors associated with the condition.

Summary:

• Lifetime prevalence of bipolar disorder is approximately 1% in the general population.
• Incidence estimates range from 0.3 to 3 cases per 10,000 people.
• The disorder affects men and women equally and is more common in urban settings and among unmarried individuals.
• Mean age of onset is around 20 years, with a higher prevalence in those born after 1930-1940.
• Bipolar disorder frequently co-occurs with alcoholism and drug dependence.

Impact:

• Provides essential data for public health planning and resource allocation for bipolar disorder.
• Informs clinical practice by identifying demographic and comorbidity patterns.
• Contributes to a better understanding of the epidemiology of bipolar disorder for future research.
