[Abstract] Objective To explore the role of impulsivity in the cognitive impairment of manic episodes in bipolar I disorder. Methods A total of 100 patients with bipolar I disorder manic episodes in our hospital from July 2018 to July 2020 as the observation group, and 100 normal people who underwent psychological tests were selected as the control group. The repetitive neuropsychological state test (RBANS) was used to evaluate the cognitive function of the two groups, and the Chinese version of the Barratt-11 Impulsivity Scale (BIS-11) was used to evaluate impulsivity. And Pearson was used to analyze the relationship between impulsivity and cognitive function. Results The visual breadth and immediate memory scores in the RBANS scale of the observation group were significantly higher than those of the control group, and the differences were statistically significant (P<0.05). The scores of exercises, unplanned and cognitive impulsivity in the BIS-11 scale of the observation group were significantly higher than those of the control group, and the differences were statistically significant (P<0.05). The motor impulsivity score in the BIS-11 scale for patients with bipolar I disorder manic episodes is negatively correlated with the speech function and attention in the RBANS scale, and the unplanned impulsivity score is negatively correlated with vision span and attention, and cognitive impulsivity It was negatively correlated with immediate memory, delayed memory, and attention (P<0.05). Conclusion Patients with bipolar I disorder manic episodes all have a certain degree of cognitive impairment, their impulsivity is high, and they may participate in cognitive impairment.
