The Neuropsychological Screening Battery for Hispanics (NeSBHIS) was developed to address the growing need for linguistically appropriate Spanish-language assessment measures. Despite the potential benefits to clinical practice, no prior study has assessed its diagnostic validity in populations with epilepsy. One hundred and fifteen patients with confirmed epilepsy were evaluated via the NeSBHIS; these data were standardized according to age- and education-based norms. Performance decrements were observed in more than 40% of participants on measures of processing speed and naming. Deficits in verbal and visual recall were also exhibited by 29 and 26% of the sample, respectively. No significant differences in test performance emerged between patients with VEEG evidence of left (N=48) versus right (N=24) temporal lobe epilepsy. Although the NeSBHIS is sensitive to the cognitive impairments commonly observed in populations with epilepsy, there are limitations to its ability to identify lateralized neuropsychological impairment in patients with temporal lobe epilepsy

The convergent validity and clinical utility of two parent-report child behavior rating scales, the Behavior Assessment System for Children-Parent Rating Scales (BASC-PRS) and Child Behavior Checklist/Ages 6-18 (CBCL), in children with epilepsy were examined. Analogous broadband and narrowband behavior rating scales were evaluated in 60 subjects aged 6-17 years (mean=11.0, SD=3.4) with Full Scale IQ >70. Correlations for each similarly labeled scale were statistically significant (P<0.002) and greater with broadband (r=0.71-0.79) than with narrowband (r=0.41-0.78) scales. The BASC captured significantly less composite internalizing symptoms (P<0.002), but more unusual thought processes (P<0.0002) and attention problems versus a CBCL DSM-oriented attention-deficit/hyperactivity disorder scale (P<0.002). Variation in the correlations between measures may stem from underlying differences between rationally-and empirically-derived approaches to test construction. Both the CBCL and BASC have diagnostic and clinical utility in assessing behavior problems in pediatric epilepsy

Lesional epilepsy is thought to be a direct consequence of focal brain lesions of dysgenetic, neoplastic, vascular, or traumatic origin. It has been estimated that at least half of all epilepsies are the result of such lesions. The current discussion includes an overview of the cognitive and behavioral presentations in adults with epilepsy secondary to focal pathology. The neuropsychological presentation in this population is influenced by many factors, including the location and nature of the underlying lesion, seizure characteristics, the effects of treatment, and patient variables. Few studies attempt to disentangle the specific contributions of these variables to cognitive performance. However, where available studies examining the separable effects of seizure-related variables on cognitive functioning in individuals with lesional epilepsy are also reviewed. This overview includes a discussion of focal malformations of cortical and vascular development and select foreign tissue and acquired lesions

In Tuberous sclerosis complex (TSC), neurological dysfunction, usually in association with epilepsy, is responsible for the greatest degree of disease-related disability. Epilepsy surgery is increasingly recognized as a therapeutic option given the often medication-resistant nature of the disease. Seven subjects with medically refractory epilepsy associated with TSC, who underwent surgery at a tertiary care epilepsy center and in whom both preoperative and postoperative neuropsychological data were available, were examined. The Vineland Adaptive Behavior Scales, and in one case, the WISC-III were utilized. Postoperatively, the composite standard scores declined in six of the seven subjects, although for the most part this decline was quite modest (8 points or less in 5/6 subjects). The mean overall developmental/intellectual quotients were comparable across assessments (preoperative M = 55, SD = 20.3; postoperative M = 49 SD = 16.6). Good outcomes appeared to be related to seizure relief. Age estimates of developmental level indicated developmental progress in the majority of subjects in the current sample, and may yield greater clinical information for individuals with developmental delay than do standard scores
