ReviewTemporal lobe epilepsy: where do the seizures really begin?
Defining precisely the site of seizure onset has important implications for our understanding of the pathophysiology of temporal lobe epilepsy, as well as for the surgical treatment of the disorder. Removal of the limbic areas of the medial temporal lobe has led to a high rate of seizure control, but the relatively large number of patients for whom seizure control is incomplete, as well as the low rate of surgical cure, suggests that the focus extends beyond the usual limits of surgical resection. ⋯ In this review, we examine current information about the pathology and physiology of mesial temporal lobe epilepsy syndrome, with special emphasis on the distribution of the changes and patterns of seizure onset. We then propose a hypothesis for the nature of the seizure focus in this disorder and discuss its clinical implications, with the ultimate goal of improving surgical outcomes and developing nonsurgical therapies that may improve seizure control.

ReviewNeurocognitive and behavioral functioning in frontal lobe epilepsy: a review.
Frontal lobe epilepsy (FLE) is a seizure disorder with a lower prevalence than temporal lobe epilepsy (TLE). Despite its consequences on cognitive and emotional well-being, the neuropsychology of FLE has not been well studied. ⋯ This review aims to illustrate the most relevant neurocognitive dimensions, psychiatric comorbidity, and postoperative neuropsychological outcome of FLE. Methodological suggestions for future research are also included by critically reviewing the existing literature.

The objective of this study was to investigate the utility of levetiracetam (LEV) in children with refractory status epilepticus (RSE). Records of children with RSE who received LEV as adjunctive therapy were reviewed. Over a 7-year period, 11 children had received LEV for RSE. ⋯ All responding patients were on LEV doses >or= 30 mg/kg/day (median 40 mg/kg/day). No significant adverse effects of LEV were reported. LEV may be an effective and safe adjuvant therapy in children with RSE.

Generic substitution in the treatment of epilepsy: patient and physician perceptions.
Generic substitution of branded antiepileptic drugs (AEDs) has sparked recent debates. We sought to understand perceptions about generic AED substitution and how these guide prescribing. Surveys were conducted among 550 adult patients with self-reported epilepsy and 606 physicians who treat patients with epilepsy. ⋯ About half of physicians were extremely/very likely to request that brand AEDs not be substituted with a generic. In conclusion, perceptions among physicians and patients do not align with the FDA position that generic AEDs have the same clinical effect and safety profile as branded AEDs. Additional investigation on bioequivalence may help address ongoing concerns and inform policy-making decisions.

Prevalence of self-reported epilepsy, health care access, and health behaviors among adults in South Carolina.
Behavioral Risk Factor Surveillance System data from South Carolina for 2003-2005 were used to determine epilepsy prevalence and prevalence variation by demographic subgroups, and to compare health insurance coverage, health care visits, and health-related behaviors among persons with epilepsy and the general population. Two percent of respondents reported they had ever been told by a doctor that they had epilepsy, and 1% reported active epilepsy. ⋯ Persons with epilepsy were more likely to smoke and have less physical activity. Persons with epilepsy need better access to health care, as well as interventions focused on smoking cessation and increased physical activity.
