Sustained attention in bipolar I disorder patients with familial psychosis and their first-degree relatives

Sustained attention (SA) was examined in patients with familial, psychotic Bipolar Disorder (BD) (n=43), their non-bipolar, non-psychotic relatives (n=44) and controls (n=47). Patients were impaired compared to relatives, but the latter did not differ from controls. Having a relative with familial, psychotic BD does not confer risk for SA deficits.
