The mechanisms by which brain insults lead to subsequent epilepsy remain unclear. Insults, including trauma, stroke, tumors, infections, and long seizures [status epilepticus (SE)], create a neuronal state of increased metabolic demand or decreased energy supply. Neurons express molecules that monitor their metabolic state, including sirtuins (Sirts). Sirtuins deacetylate cytoplasmic proteins and nuclear histones, and their epigenetic modulation of the chromatin governs the expression of many genes, influencing neuronal properties...

Temporal lobe epilepsy (TLE) is the most common type of acquired epilepsy in adults. TLE can develop after diverse brain insults, including traumatic brain injury, infections, stroke, or prolonged status epilepticus (SE). Post-SE rodent models of TLE are widely used to understand mechanisms of epileptogenesis and develop treatments for epilepsy prevention. In this respect, the intrahippocampal kainate model of TLE in mice is of interest, because highly frequent spontaneous electrographic seizures develop in the kainate focus, allowing evaluation of both anti-seizure and anti-epileptogenic effects of novel drugs with only short EEG recording periods, which is not possible in any other model of TLE, including the intrahippocampal kainate model in rats...

The experience of Supernumerary Phantom Limbs (SPLs) is a rare phenomenon known to occur following a variety of neurological ailments. This case report details visualized supernumerary phantom arms and legs in a polytrauma patient with suspicion of seizure as the primary contributing factor. Less than thirty cases of SPLs have been previously described. SPLs are usually confined to the phantom proprioception/sensation of the limb with only six prior cases reporting visualized SPLs, all of which occurred in the setting of isolated stroke...

PURPOSE: To identify risk factors for the development of epilepsy after pediatric stroke. METHODS: Retrospective analysis of hospital charts of 93 children and adolescents with post-neonatal non-traumatic stroke and a minimum follow-up of two years. Seizures during the first 48 h after onset of stroke symptoms were defined as "early seizures"; when two or more seizures occurred after this period, the patient was classified as "epileptic". RESULTS: Early seizures, young age at stroke and MRI evidence of cortical involvement were observed more frequently in the children who developed epilepsy...

BACKGROUND: Contributors to post-stroke seizure research have advocated the need for prospective studies of acute symptomatic seizures after stroke. Identification of the patient at risk of seizure and the impact of the event on outcome is a prerequisite for this kind of research. The aim of this study was to identify risk factors, make an outline for a risk score, and look at consequences of seizure on short-time clinical outcomes. METHODS: This registry-based study included patients with ischemic stroke admitted between 2007 and 2013...

: We describe the case of a young Hispanic female who presented with thyrotoxicosis with seizures and ischemic stroke. She was diagnosed with a rare vasculopathy - moyamoya syndrome. After starting antithyroid therapy, her neurologic symptoms did not improve. Acute neurosurgical intervention had relieved her symptoms in the immediate post-operative period after re-anastomosis surgery. However, 2 post-operative days later, she was found to be in status epilepticus and in hyperthyroid state...

OBJECTIVE: Seizures may occur in close temporal association with a stroke or after a variable interval. Moreover, epilepsy is often encountered in patients with leukoaraiosis. Although early post-stroke seizures have been studied extensively, less attention has been paid to post-stroke epilepsy (PSE) and to epilepsy associated with leukoaraiosis (EAL). The aim of this paper is to review data concerning pathophysiology, prognosis, and treatment of PSE and EAL. METHODS: We performed an extensive literature search to identify experimental and clinical articles on PSE and EAL...

BACKGROUND: Non-immersive virtual reality is an emerging strategy to enhance motor performance for stroke rehabilitation. There has been rapid adoption of non-immersive virtual reality as a rehabilitation strategy despite the limited evidence about its safety and effectiveness. Our aim was to compare the safety and efficacy of virtual reality with recreational therapy on motor recovery in patients after an acute ischaemic stroke. METHODS: In this randomised, controlled, single-blind, parallel-group trial we enrolled adults (aged 18-85 years) who had a first-ever ischaemic stroke and a motor deficit of the upper extremity score of 3 or more (measured with the Chedoke-McMaster scale) within 3 months of randomisation from 14 in-patient stroke rehabilitation units from four countries (Canada [11], Argentina [1], Peru [1], and Thailand [1])...

Stroke is the second leading cause of death and the most important cause of adult disability worldwide and in Croatia. In the past, stroke was almost exclusively considered to be a disease of the elderly; however, today the age limit has considerably lowered towards younger age. The aim of this study was to determine age and gender impact on stroke patients in a Croatian urban area during one-year survey. The study included all acute stroke patients admitted to our Department in 2004. A compiled stroke questionnaire was fulfilled during hospitalization by medical personnel on the following items: stroke risk factors including lifestyle habits (smoking and alcohol), pre-stroke physical ability evaluation, stroke evolution data, laboratory and computed tomography findings, outcome data and post-stroke disability assessment...

PURPOSE: Post-stroke seizures are considered as a major cause of epilepsy in adults. The pathophysiologic mechanisms resulting in post-stroke seizures are not fully understood. The present study attempted to reveal a new mechanism underlying neuronal hyperexcitability responsible to the seizure development after ischemic stroke. METHODS: Transient global ischemia was produced in adult Wistar rats using the 4-vessel occlusion (4-VO) method. The spontaneous behavioral seizures were defined by the Racine scale III-V...

Stroke survivors often recover from motor deficits, either spontaneously or with the support of rehabilitative training. Since tonic GABAergic inhibition controls network excitability, it may be involved in recovery. Middle cerebral artery occlusion in rodents reduces tonic GABAergic inhibition in the structurally intact motor cortex (M1). Transcript and protein abundance of the extrasynaptic GABAA-receptor complex α4β3δ are concurrently reduced (δ-GABAARs). In vivo and in vitro analyses show that stroke-induced glutamate release activates NMDA receptors, thereby reducing KCC2 transporters and down-regulates δ-GABAARs...

Seizures are among the most common neurological sequelae of stroke, and ischemic insult in diabetes notably increases the incidence of seizures. Recent studies indicated that autophagy influences the outcome of stroke and involved in epileptogenesis. However, the association of autophagy and post-ischemic seizures in diabetes remains unclear. The present study aimed to reveal the involvement of autophagy in the seizures following cerebral ischemia in diabetes. Diabetes was induced in adult male Wistar rats by intraperitoneal injection of streptozotocin (STZ)...
