Some studies have indicated that there are wide variations on incidence and prevalence of bipolar disorder in specific populations.
The occurrence of bipolar affective disorder and the age at onset was studied in both genders among the hospitalized Finnish population.
The annual rate of all hospitalized patients with bipolar disorder was 0.03%. Of these, 2% were under 20 years, 14% under 30 years, 61% under 50 years and 81% under 60 years of age.
The 1-year incidence was highest in the age group 50-59 years in males and 40-49 years in females.
The low prevalence and incidence of bipolar disorder in Finland may be due to late onset-age.
The study is based on hospital-treated bipolar disorder patients.
Clinical relevance : We have presented previously unreported differences between the age of onset of bipolar disorder in Finland compared with other countries.
