Abstract Background The clinical presentation of bipolar disorders, though clearly recognized in adolescents, remains controversial in younger children and across cultures. The aim of this study was to compare the clinical presentation of bipolar disorders in Italian and American children between ages 5 and 12 years. Methods Sixty-seven children from six outpatient programs were enrolled (Italian sample: n =40; American sample: n =28) between January 2010 and June 2011. Children and their parents were interviewed by experienced clinicians using the Washington University in St. Louis Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present, Lifetime Version (WASH-U K-SADS). Results Italian children scored significantly higher on ratings of “elevated mood” ( p =0.002), whereas American children scored significantly higher on ratings of “flight of ideas” ( p =0.001) and “productivity” ( p =0.001). Rates of comorbidity were different between groups. Limitations Data were acquired from several sites in Italy as compared to from a single American site. Medication and educational information were not systematically collected. Furthermore, the sample collected may only reflect characteristics of a less severely ill group of bipolar children. Conclusions Our comparison of Italian and American children with early onset bipolar disorders found that the phenotype of bipolar spectrum disorders is largely shared across cultures, although psychiatric comorbidities differed.
