Abstract: Objective To explore the characteristic of intelligence, personality and mentality of patients with intractable epilepsy and analyzethe related factors on intelligence. Methods 68 patients with intractable epilepsy and 60 healthy persons were assessed with Raven'sstandard progressive matrices (SPM), Eysenck personality questionnaire (EPQ) and 90 symptoms checklist (SCL-90). The related factors onintelligence were analyzed. Results Compared with controls, the total score and IQ of SPM of the patients decreased significantly (P<0.05).There were 51.4% of intellectual deficiency in patients with intractable epilepsy, which was higher than that of controls (1.7%) (P<0.05).There was no significant difference in score of EPQ and the proportion of personality type between 2 groups (P>0.05). The total score ofSCL-90 and the factor score, such as somatization, interpersonal sensitivity, depression, anxiety and hostility in patients were higher thanthose in controls(P<0.05). Various factors, including the onset age, course of disease, seizure types, frequency, duration, number of drug, thescores of SCL-90 were correlated with the intelligence of epileptic patients (P<0.05). Conclusion The intelligence of many patients with intractableepilepsy were damaged, and many patients were with various psychological barriers. The onset age, course of disease, seizuretypes, frequency, duration and number of drug were important factors related with intellectual disorders in patients with intractable epilepsy.
