Abstract

Objective：Recent reports have consistently demonstrated cognitive and emotional processing deficits in patients with bipolar disorder, but their relationship with psychotic symptoms remains unclear. We investigated whether a history of psychotic symptoms in the course of bipolar I disorder is associated with poor performance of sustained attention to facial stimuli.
Method：The Sustained Attention to Response Task (SART) was performed to measure attention capacities in 47 euthymic patients with or without previous psychotic symptoms (hallucination and/or delusion). Happy, neutral, and fearful faces, originated from Ekman’s facial expression pictures, as well as digit ‘3’ were used as target stimuli in happy, neutral, fear and digit task conditions, respectively.
Result：There was not any significant difference in performance of the SART, measured with correct response rate, commission error rate, correct response time, and efficiency estimate, across all 4 test conditions between bipolar subjects with or without a history of psychotic feature.
Conclusion：These results suggest that a history of psychotic symptoms in bipolar I disorder may not be associated with sustained attention to facial and digit stimuli. Further research on euthymic bipolar patients classified with more carefully specified psychotic symptoms is required to confirm these findings.
