Abstract: Objective To evaluate whether epilepsy patients are complicated with cognitive impairment and emotional disorders or not by comparing the processing of different emotional words in patients with generalized seizures.Methods Event-related potential (ERP) technique was used to record the differences of emotional reactions stimulated by the three different emotional words in patients with generalized seizures and in controls.Results Compared with control group,the epilepsy group showed significant differences in Hamilton depression scale scores,accuracy rate and average reaction time (all P<0.05) and showed longer reaction time after the stimulus of negative emotional words.Statistical parameters presented by T-test displayed that ERPs in bilateral posterior temporal regions and occipital pole showed significant differences between two groups after 130-160ms stimulus of three different emotional words (P<0.05);The two groups indicated significant differences at the stage of attention processing after 400-600ms negative emotional stimulus and at the stage of further processing after positive emotional stimulus (P<0.05);In addition,ERPs in frontal pole and front frontal region showed significant differences between two groups after 310-950ms neutral stimulus (P<0.05).Conclusion Patients with generalized seizures have high occurrence rate of emotional disorders such as depression,and the stimulus of emotional words can decrease efficiency,prolong reaction time and increase accuracy rate.
