The successful identification of promising investigational therapies for the treatment of epilepsy can be credited to the use of numerous animal models of seizure and epilepsy for over 80 years. In this time, the maximal electroshock test in mice and rats, the subcutaneous pentylenetetrazol test in mice and rats, and more recently the 6 Hz assay in mice, have been utilized as primary models of electrically or chemically-evoked seizures in neurologically intact rodents. In addition, rodent kindling models, in which chronic network hyperexcitability has developed, have been used to identify new agents...

Cerebral cavernous malformations (CCMs) are vascular defects of the CNS that arise from loss of integrity of the endothelial cells lining blood capillaries, causing leakage of blood into the brain [1]. This results in headaches, seizures, and/or hemorrhagic stroke, depending on the location of the lesion. CCM affects 0.5% of the population and follows an autosomal dominant inheritance pattern caused by mutations in one of the three genes: CCM1 (gene name KRIT1), CCM2 (also known as malcavernin or OSM), and CCM3 (gene name PDCD10) [2, 3], with the earliest onset and most severe prognosis occurring in CCM3 patients [4]...

Status epilepticus (SE) is an important neurological emergency. It is defined as seizures lasting for 5 minutes or more or recurrent seizures without recovery of consciousness to baseline between the attacks. Refractory SE (RSE) is defined as SE persisting despite sufficient dose of benzodiazepines and at least one antiepileptic drug (AED), irrespective of time. Super refractory SE (SRSE) is defined as SE that continues for 24 hours or more after the use of anesthetic therapy, including cases that recur on weaning of the anesthestic agent...

BACKGROUND: Ischemic stroke is a leading cause of new-onset seizures. Cortical ischemia and large ischemic lesion size are among the most consistently reported risk factors for post-stroke seizures. Alberta Stroke Program Early CT Score (ASPECTS) is a simple and reliable tool for quantifying the extent of cerebral ischemia and may function as a screening tool for patients with high risk of seizure development. We investigated the association of post-stroke seizures with the extent of ischemia assessed by ASPECTS and with cortical involvement identified on non-contrast CT (NCCT)...

BACKGROUND: Pediatric arterial ischemic stroke remains incompletely understood. Population-based epidemiological data inform clinical trial design but are scant in this condition. We aimed to determine age-specific epidemiological characteristics of arterial ischemic stroke in neonates (birth to 28 days) and older children (29 days to 18 years). METHODS: We conducted a 16-year, prospective, national population-based study, the Canadian Pediatric Ischemic Stroke Registry, across all 16 Canadian acute care children's hospitals...

RATIONALE: Primary angiitis of the central nervous system (PACNS) is an inflammatory disease involving cerebrovascular and parenchymal, and solitary tumor-like mass lesion of PACNS (TLML-PACNS) is frequently misdiagnosed as neoplastic or other inflammatory diseases. However, seizure syndrome as a first manifestation of TLML-PACNS has rarely reported before. PATIENT CONCERNS: Here, we report 2 cases of seizure syndrome, which was the first sign that presented prior to the diagnosis of TLML-PACNS by brain biopsy...

A 26-year-old man presented to the emergency department with new-onset generalised tonic-clonic seizures. His clinical picture suggested either autoimmune or infectious encephalitis while his brain imaging raised the possibility of a stroke. A detailed developmental and childhood medical history added suspicion of a mitochondrial defect to the differential. After several molecular genetic analyses, an uncommon mitochondrial mutation was confirmed, unequivocally consistent with mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) syndrome...

Cannabinoids are the most commonly used illegal substances in the world [1]. Synthetic Cannabinoids (SCB) are also known as "Spice", "K2", "Spike", "herbal incense", "Cloud 9", "Mojo" and many others are becoming a large public health concern due to their increasing use, unpredictable toxicity, and abuse potential [2]. The most common reported toxicities with SCB use based on studies using Texas Poison control record are tachycardia, agitation and irritability, drowsiness, hallucinations, delusions, hypertension, nausea, confusion, dizziness, vertigo, chest pain, acute kidney injury, seizures, heart attacks and both ischemic and hemorrhagic strokes [3]...

Acid-sensing ion channels (ASICs) are associated with many pathophysiological processes, such as neuronal death during ischemic stroke, epileptic seizure and nociception. However, there is a dearth of ASIC-specific therapeutic blockers. Here we report that quercetin, a plant flavonoid, which is known for its neuroprotective effect, reversibly inhibits homomeric rat ASIC1a, ASIC2a and ASIC3 with an IC50 of about 2µM. Also, quercetin prevents low pH-induced intracellular calcium rise and cell death in HEK-293 cells, which have endogenous expression of ASIC1a and 2a...

PURPOSE: As part of our efforts to develop a non-invasive facial nerve stimulator as an emergency treatment for ischemic stroke, we considered possible safety consequences if the technology was misapplied to stroke mimics, e.g., seizure. We hypothesized that magnetic facial nerve stimulation would worsen epileptiform activity in two animal models of active seizures. The rat intraperitoneal kainate model and pig intracortical penicillin model were employed. Magnetic facial nerve stimulation was delivered unilaterally at a variety of stimulation parameters, and the effect on ictal epileptiform activity measured by electroencephalography was determined according to an established categorical scale...

BACKGROUND AND PURPOSE: Despite quality improvement programs such as the American Heart Association/American Stroke Association Target Stroke initiative, a substantial portion of acute ischemic stroke patients are still treated with tissue-type plasminogen activator (alteplase) later than 60 minutes from arrival. This study aims to describe the documented reasons for delays and the associations between reasons for delays and patient outcomes. METHODS: We analyzed the characteristics of 55 296 patients who received intravenous alteplase in 1422 hospitals participating in Get With The Guidelines-Stroke from October 2012 to April 2015, excluding transferred patients and inpatient strokes...

Cerebral venous thrombosis (CVT) has a broad spectrum of clinical presentation compared to arterial etiology. Seizure is one of the common symptoms and is more frequent than in other stroke types. Hence, transient neurological symptoms in CVT patients are usually due to epileptic seizures, while transient repetitive movement disorder is extremely rare except as a complication of epilepsy. We report a case of CVT in the superior sagittal sinus with a 1-year history of paroxysmal kinetic tremor without evident epilepsy...
