Identifying the epileptogenic zone in interictal resting-state MEG source-space networks

Summary

Objective

In one third of patients, seizures remain after epilepsy surgery, meaning that improved preoperative evaluation methods are needed to identify the epileptogenic zone. A potential framework for such a method is network theory, as it can be applied to noninvasive recordings, even in the absence of epileptiform activity. Our aim was to identify the epileptogenic zone on the basis of hub status of local brain areas in interictal magnetoencephalography (MEG) networks.

Methods

Preoperative eyes-closed resting-state MEG recordings were ...

A novel c132-134del mutation in Unverricht-Lundborg disease and the review of literature of heterozygous compound patients

Summary

Unverricht-Lundborg disease or progressive myoclonic epilepsy type 1 (EPM1) is an autosomal recessive disease caused by mutation of the cystatin B gene (CSTB), located on chromosome 21q22.3. The most common mutation is an expansion of unstable dodecamer repetition (CCCCGCCCCGCG), whereas other types of mutations are rare. Among these, heterozygous compound mutations are described to induce a more severe phenotype than that of homozygous dodecameric repetition. We report two siblings affected by heterozygous compound mutations carrying a novel ...

The burden of premature mortality of epilepsy in high-income countries: A systematic review from the Mortality Task Force of the International League Against Epilepsy

Summary

Since previous reviews of epidemiologic studies of premature mortality among people with epilepsy were completed several years ago, a large body of new evidence about this subject has been published. We aim to update prior reviews of mortality in epilepsy and to reevaluate and quantify the risks, potential risk factors, and causes of these deaths. We systematically searched the Medline and Embase databases to identify published reports describing mortality risks in cohorts and populations of people with ...

Rapid and safe response to low-dose carbamazepine in neonatal epilepsy

Summary

Objective

To evaluate treatment responses in benign familial neonatal epilepsy (BFNE).

Methods

We recruited patients with BFNE through a multicenter international collaboration and reviewed electroclinical and genetic details, and treatment response. All patients were tested at minimum for mutations/deletions in the KCNQ2, KCNQ3, and SCN2A genes.

Results

Nineteen patients were included in this study. A family history of neonatal seizures was positive in 16 patients, and one additional patient had a family history of infantile seizures. Mutations or deletions of ...
