Nonketotic hyperglycinemia (NKH) is a devastating inborn error of glycine metabolism caused by deficient activity of the glycine cleavage enzyme. Classically, patients present with lethargy, hypotonia, myoclonic jerks, transient respiratory depression in the first week of life and often progress to death. Surviving infants have profound psychomotor retardation, refractory epilepsy and poor quality of life. Currently, no effective therapeutic avenues exist for severe NKH. Ketogenic diet (KD) has been trialled only in a small group of patients with neonatal NKH and early myoclonic encephalopathy, in whom significant improvements in seizure control were reported...

Background: The use of the anterior nucleus of thalamus (ANT) as a target for treatment of pharmacoresistant epilepsy is based on its crucial role in seizure propagation. We describe results of chronic bilateral ANT stimulation and bilateral ANT lesions in 31 patients with refractory epilepsy. Methods: ANT DBS was performed in 12 patients (group I) and bilateral stereotactic radiofrequency lesions of ANT were performed in 19 patients (group II). Targeting was based on stereotactic atlas information with correction of the final coordinates according to the location of anatomical landmarks and intraoperative microelectrode recording data...

Lithium, a classic mood stabilizer, prevents apoptosis-dependent cellular death and has garnered considerable interest as a neuroprotective agent that is efficacious in the treatment of many neurological diseases. However, the effects of lithium in epilepsy remain controversial. We found that different doses of lithium affect epileptic seizure activity and bidirectionally modulate the susceptibility to and severity of seizures induced by pilocarpine in rats. Recently, it has been demonstrated that systematically administered lithium affects the powers of hippocampal gamma and theta oscillations in baseline electroencephalograms...

Objective: Generalized tonic-clonic seizures are accompanied by cardiovascular and respiratory sequelae that threaten survival. The frequency of these seizures is a major risk factor for sudden unexpected death in epilepsy (SUDEP), a leading cause of untimely death in epilepsy. The circumstances accompanying such fatal events suggest a cardiovascular or respiratory failure induced by unknown neural processes rather than an inherent cardiac or lung deficiency. Certain cortical regions, especially the insular, cingulate, and orbitofrontal cortices, are key structures that integrate sensory input and influence diencephalic and brainstem regions regulating blood pressure, cardiac rhythm, and respiration; output from those cortical regions compromised by epilepsy-associated injury may lead to cardiorespiratory dysregulation...

Drug-resistant epileptic encephalopathy such as Dravet syndrome presents with autistic symptoms. Three cases with autism spectrum disorder with comorbid Dravet syndrome were assessed. All the cases presented with onset of seizures before a year and with autistic features. The patients responded to a combination of antiepileptic drugs (AEDs), resulting in reduced frequency of seizures and behavioral issues. Contrary to the belief that both epilepsy and use of AEDs have adverse impact on the cognition of children with an early onset of epilepsy, we found improvement in the symptoms of our patients who presented with autism and epilepsy...

AIM: As the population ages, epilepsy among elderly people is increasing. Epileptic seizures in the elderly are mostly complex partial seizures without convulsions, so more caution is needed in the diagnosis of epilepsy. If epileptic seizures in the context of memory impairment are overlooked, epilepsy may be misdiagnosed as dementia. However, in older patients with epilepsy, there is a possibility that cognitive function may be impaired in the interictal phase. This study aims to investigate the efficacy of anti-epileptic drug (AED) treatment for patients with cognitive impairment and interictal epileptiform discharge (IED) on electroencephalography...

The identification and characterization of sudden unexpected deaths in epilepsy (SUDEP) may be improved, helping to optimize prevention and intervention. We set out to assess the frequency and demographic and clinical characteristics of SUDEP cases in a sudden death cohort. All out-of-hospital deaths were investigated from March 1, 2013 to February 28, 2015 in Wake County, NC, attended by the Emergency Medical Services. Cases were screened and adjudicated by three physicians to identify sudden death cases from any cause among free-living adults, aged 18-64...
