Randomized Controlled Trial Comparative Study
Consequences of antiepileptic drug withdrawal: a randomized, double-blind study (Akershus Study).
Despite side effects associated with the use of antiepileptic drugs (AEDs), withdrawal of AEDs remains controversial, even after prolonged seizure freedom. The main objective of this study was to assess the effects of AED withdrawal on cognitive functions, seizure relapse, health-related quality of life (HRQOL), and EEG results. Additionally, potential predictors for freedom from seizures after AED withdrawal were studied. ⋯ Seizure-free epilepsy patients on AED monotherapy who taper their medication may improve neuropsychological performance with a relative risk of seizure relapse of 2.46, compared to those continuing therapy.

To estimate the cost-effectiveness of pregabalin as add-on therapy in patients with refractory partial epilepsy. ⋯ In patients with refractory partial epilepsy, the cost-effectiveness of pregabalin 300 mg/day compares favorably with published estimates of cost-effectiveness for other add-on antiepileptic drugs.

Mutations in the ATP1A2 gene have been described in families with familial hemiplegic migraine (FHM). FHM is a variant of migraine with aura characterized by the occurrence of hemiplegia during the aura. Within several FHM families, some patients also had epileptic seizures. In this study we tested the hypothesis that mutations in ATP1A2 may be common in patients presenting with epilepsy and migraine. ⋯ This study shows that a history of migraine and a family history of both epilepsy and migraine should be obtained in all patients presenting with epilepsy in the epilepsy clinic. It may be worthwhile to screen patients with a combination of epilepsy and migraine and a positive family history of either migraine or epilepsy for mutations in the ATP1A2 gene.

Comparative Study
Prevalence and cost of nonadherence with antiepileptic drugs in an adult managed care population.
This study assessed the extent of refill nonadherence with antiepileptic drugs (AEDs) and the potential association between AED nonadherence and health care costs in an adult-managed care population. ⋯ Adherence with AEDs among adult epilepsy patients is suboptimal and nonadherence appears to be associated with increased health care costs. Efforts to promote AED adherence may lead to cost savings for managed care systems.

To establish the efficacy and safety of low-frequency electrical stimulation for cortical brain mapping. ⋯ 5- and 10-Hz stimulation are as effective for mapping cortical function as 50-Hz stimulation and produce fewer ADs. We recommend that mapping of cortical function be started with 5-Hz-frequency stimulation. Higher frequencies should be used in suspect cortex if no symptoms or signs are produced with 5-Hz stimulation.
