title: Epilepsy surgery outcome among US veterans.
abstract: We retrospectively studied the outcome of anterior temporal lobectomy (ATL) among a population of veterans and evaluated outcome related to comorbidities. Veterans who underwent ATL between 1990 and 2001 at the Veterans Administration Hospital in Madison, Wisconsin, were included. Data related to postoperative seizure outcome, quality of life outcome, and employment outcome were collected. Factors associated with favorable outcome and outcome related to comorbidities were evaluated. Twenty-seven patients were entered into the study. The mean age at onset of seizures was 25 years (+/-10.2). History of a non-substance abuse psychiatric diagnosis, and substance abuse was present in 26% (7/27) and 30% (9/27), respectively, prior to surgery. While 66.6% (18/27) had a good outcome (Engel's Class I), no difference in the frequency of good outcome was seen among the patients with a history of substance abuse, other psychiatric diagnosis (71%), or no psychiatric diagnosis (67%). There was a significant correlation between seizure outcome and quality of life score (r(s)=0.67, p<0.001) and postoperative employment gains (r(s)=0.48, p=0.01). Outcomes among veterans that underwent ATL can be satisfactory even in the context of the late mean age of epilepsy onset and the psychiatric diagnoses that were present in this sample.
