Dosage, time, and polytherapy dependent effects of different levetiracetam regimens on cognitive function.

Objective: Cognitive impairment is a potential drawback of antiseizure medications. This study aimed to evaluate the impact of different levetiracetam drug regimens on cognitive function.

Methods: A retrospective analysis identified 221 patients diagnosed with seizures who underwent cognitive screening.

Prevalence and Incidence of Drug-Resistant Temporal Lobe Epilepsy in Qatar.

Background: Information on the epidemiology of temporal lobe epilepsy associated with hippocampal sclerosis (TLE-HS) from Qatar and the developing countries is scarce. To acquire knowledge on the incidence and prevalence of drug-resistant TLE-HS in Qatar, we designed this analytical and extrapolative systematic review of the existing literature.

Material And Methods: We searched the electronic database PubMed from 1947 until April, 2018, using the following search terms in the title: "epilepsy" OR "temporal lobe" OR "hippocampal sclerosis" AND "epidemiology" OR "incidence" OR "prevalence.

Unexpected brain imaging findings in patients with seizures.

New imaging technologies have advanced our ability to localize the epileptogenic zone in patients with epilepsy. As a result of the constant improvement of the image quality, magnetic resonance imaging (MRI) has become the most important ancillary tool in the management of patients with epilepsy. Magnetic resonance imaging for the evaluation of patients with epilepsy should be done using a special temporal lobe protocol and read by physicians experienced with the findings in patients with epilepsy.

Hypothalamic hamartoma presenting with gelastic seizures, generalized convulsions, and ictal psychosis.

We report a case of hypothalamic hamartoma in an adult female who presented with gelastic seizures, generalized convulsions, and ictal aggressive psychotic behavior. Anticonvulsant treatment was ineffective in controlling the epileptic seizures. Surgical excision after accurate imaging diagnosis 3 decades after the onset of symptoms markedly ameliorated her condition.
