title: Psychiatric symptom changes after corticoamygdalohippocampectomy in patients with medial temporal lobe epilepsy through Symptom Checklist 90 Revised.
abstract: BACKGROUND
  Corticoamygdalohippocampectomy (anterior temporal lobe resection plus amygdalohippocampectomy) is common in epilepsy surgery. Pre- and postoperative psychiatric disorders occurred sometimes in patients with refractory medial TLE. We want to know if CAH has an affirmative effect on the psychiatric symptom of patients with medial TLE through a quantitative method.
  
  
  METHODS
  Sixty-two patients with medial TLE who had CAH accomplished SCL-90-R questionnaires thrice (presurgical and postsurgical 1 and 2 years). Average GSI scores in SCL-90-R were calculated and statistically analyzed.
  
  
  RESULTS
  There was no statistical difference in the presurgical average GSI scores between Engel I and Engel II to IV subgroup. Postoperative 1 and 2 years' average GSI scores of Engel II to IV subgroup were both statistically higher than those of Engel I subgroup. There were no statistical differences between other subgroups in different time. Postsurgical 1 and 2 years' average GSI scores of the whole group and Engel I subgroup were statistically lower than those of presurgery. Postoperative 2 years' average GSI scores of the whole group and Engel I subgroup were statistically lower than those of postsurgical 1 year. For Engel II to IV subgroup, there were no statistical differences among the average GSI scores in different time.
  
  
  CONCLUSIONS
  Corticoamygdalohippocampectomy could improve the psychiatric symptoms of patients with TLE as assessed by the SCL-90-R. This improvement was related to the therapeutic effect and was not related to sex, lateralization, and MRI abnormality.
