Abstract

Epilepsy is a serious disorder of the brain, affects almost fifty million people in the world. About 40%

of the patients finally became refractory to epileptic drugs, especially those with temporal lobe epilepsy

(TLE). This refractory condition may cause psychosocial decline, including patient’s intelligence. Surgical

therapy has an important role in stopping further damage to brain cells caused by repeated seizures. The

elimination of the seizure after surgery will hopefully results in better intelligence score. This study aims

to find out the effect ofsurgical therapyin TLE patients after surgery. We were using a Quasi Experimental

study with One Group Pre-test and Post-test design. The samples were taken with consecutive sampling

method. Subjects were 15 TLE patients who underwent anterior temporal lobectomy and have passed at

least one year postoperative period, and also had done an intelligence quotient (IQ) test before surgery. IQ

before and after surgery were measured with WAIS and WISC-R method. The statistical tests used were

paired t-test. We found the verbal IQ after surgery(98.8±9.88(76-119)) were significantly higher(p=0.01)

comparedwithpreoperativeverbalIQ(92.7±9.60(77-113)). On the other hand, performance IQ after surgery

(98.2±8.64(82-115)) were higher compared with preoperative performance IQ (96.0±9.39(75-116)) but it was

not significant (p=0.5). Total IQ after surgery (97.8 ±7.69(81-107)) also higher compared with preoperative

total IQ (93.9±9.28(75-115)) but also not significant (p=0.08). Postoperative verbal IQ improvement was

found compared with preoperative verbal IQ.
