Abstract excerpt

BACKGROUND: Conflicting results in genetic studies of bipolar disorders may be due to the clinical and genetic heterogeneity of the disease. Age at onset of bipolar disorders may be a key indicator for identifying more homogeneous clinical subtypes. We tested whether early onset and late onset bipolar illness represent two different forms of bipolar illness in terms of clinical features, comorbidity and familial...
