CONTEXT Despite reported success, surgery for pharmacoresistant seizures is often seen as a last resort. Patients are typically referred for surgery after 20 years of seizures, often too late to avoid significant disability and premature death. OBJECTIVE We sought to determine whether surgery soon after failure of 2 antiepileptic drug (AED) trials is(More)
Removal of the anterior temporal lobe (ATL) is an effective surgical treatment for intractable temporal lobe epilepsy but carries a risk of language and verbal memory deficits. Preoperative localization of functional zones in the ATL might help reduce these risks, yet fMRI protocols in current widespread use produce very little activation in this region.(More)
OBJECTIVE To develop a multivariate risk factor model for predicting postoperative verbal memory decline in an individual patient following dominant or nondominant anterior temporal lobectomy (ATL). METHODS The authors studied 132 consecutive ATL patients who 1). were older than 16 years at surgery, 2). had estimated preoperative Full Scale IQ score of(More)
OBJECTIVE To determine the incidence and extent of exacerbation of word-finding difficulty following anterotemporal lobectomy and to identify predictors of change. DESIGN Case-series study of qualitative and quantitative changes in confrontation naming ability before surgery and 1 year after surgery. Stepwise multiple regression analysis of predictors of(More)
In North America, overall epilepsy incidence is approximately 50/100,000 per year, highest for children below five years of age, and the elderly. The best data suggest prevalence of 5-10/1000. Potential effects of gender, ethnicity, access to care and socioeconomic variables need further study. Studies of epilepsy etiology and classification mainly were(More)
PURPOSE Multiple studies have examined predictors of seizure outcomes after epilepsy surgery. Most are single-center series with limited sample size. Little information is available about the selection process for surgery and, in particular, the proportion of patients who ultimately have surgery and the characteristics that identify those who do versus(More)
OBJECTIVE To obtain prospective data regarding seizures, anxiety, depression, and quality of life (QOL) outcomes after resective epilepsy surgery. METHODS The authors characterized resective epilepsy surgery patients prospectively at yearly intervals for seizure outcome, QOL, anxiety, and depression, using standardized instruments and patient interviews.(More)
BACKGROUND In a seven-center prospective observational study of resective epilepsy surgery, the authors examined probability and predictors of entering 2-year remission and the risk of subsequent relapse. METHODS Patients aged 12 years and over were enrolled at time of referral for epilepsy surgery, and underwent standardized evaluation, treatment, and(More)
OBJECTIVE To determine changes in depression and anxiety after resective surgery. METHODS Data from subjects enrolled in a prospective multicenter study of resective epilepsy surgery were reviewed with the Beck Psychiatric Symptoms Scales (Beck Depression Inventory [BDI] and Beck Anxiety Inventory [BAI]) and Composite International Diagnostic Interview(More)
OBJECTIVE To examine the frequency of driving an automobile and characteristics associated with driving in individuals with refractory localization-related epilepsy. BACKGROUND Driving is generally restricted and monitored in people with epilepsy. Little is known about the frequency of driving and subsequent accidents specifically in individuals with(More)
