Ischemic brain injury is an important cause for seizure. Mild hypothermia of the brain or the whole body is an effective way to remit the post-stroke seizure. Our previous study revealed an implication of Notch 1 and 2 in the post-stroke seizure. This study further investigated the involvement of Notch 3 and 4 in post-stroke seizure and the effect of mild hypothermia on these two factors. A global cerebral ischemia (GCI) model was conducted in Sprague Dawley rats. Seizure activity was evaluated by the frequency of seizure attacks, seizure severity scores, and seizure discharges...

BACKGROUND: Epilepsy is a major complication of stroke. We aimed to establish whether there is an association between intravenous thrombolysis, intra-arterial thrombolysis and post stroke seizure (PSS) development. Improved understanding of the relationship between reperfusion therapies and seizure development may improve post-stroke monitoring and follow-up. METHODS: This was a retrospective, multicentre cohort study conducted at the Royal Melbourne Hospital and Jingling Hospital Nanjing...

Two patients at our center experienced florid visual hallucinations following hemispherectomy. The first patient had drug-resistant left hemispheric focal seizures at 20 months of age from a previous stroke. Following functional hemispherectomy at age 3, he experienced frightening hallucinations 1 month post-operatively lasting 3.5 months. Our second patient underwent subtotal hemispherectomy at age 6 for drug-resistant focal seizures from right hemispheric cortical dysplasia. Eighteen months later he developed scary visual hallucinations during which he would shout and throw things...

Stroke is an important cause of seizures and epilepsy in adults, particularly among the elderly. The incidence of stroke increases yearly as life expectancy increases and the number of patients with post-stroke seizures and epilepsy is also rising. Post-stroke epilepsy accounts for nearly 50% of newly diagnosed epilepsy among patients over 60 years of age. With increasing stroke awareness and advanced treatments, increased attention is paid to post-stroke seizures and epilepsy including its diagnosis and treatment...

Stroke is the most common cause of seizures and epilepsy in population stuies of adults. Seizures occur within 24 hours of the stroke in a high percent of patients. The pathogenesis of these early-onset seizures may be related to local ion shifts and release of high levels of excitotoxic neurotransmitters in the area of ischemic injury. The risk of late-onset seizures may increase over time, an underlying permanent lesion that leads to persistent chnges in neuronal excitability appears to be responsible for late-onset seizures after stroke...

BACKGROUND: Cranioplasties are an important neurosurgical procedure not only for improved cosmesis, but also for improved functional recover after craniectomy with a large cranial defect. The aim of this study was to identify predictive factors of post-cranioplasty complications using custom-made porous hydroxyapatite cranioplasty. METHODS: A retrospective review was conducted of all patients who underwent a reconstructive cranioplasty using custom-made hydroxyapatite at our institution between February 2008 to September 2017...

Seizures may occur after stroke. Though the majority of clinicians are aware of this, a consensus-based treatment and management strategy for post-stroke seizures is not available because there have only been a few large-scale studies that have explored this. This study has surveyed the actual state of medical treatment for post-stroke seizure and epilepsy in Japan. We conducted a nationwide questionnaire survey of the top 500 institutions regarding the number of cerebral infarction cases between February 2015 and May 2015...

BACKGROUND: To analyze the findings in the background EEG activity of infants who suffered perinatal stroke. METHODS: Eleven neonates born 2009-2014 diagnosed of ischemic stroke by MRI (three of them with multistroke) underwent continuous video-EEG monitoring. Visual and spectral (power spectrum and coherence) analyses of the background EEG was performed in three moments: 1) Onset of EEG recording (prior to initiate seizure treatment), 2) Post-ictal epoch (1-2 h after the last seizure), and 3) one-two days after seizure control...

PURPOSE OF REVIEW: Cerebral hyperperfusion syndrome (CHS) is a rare but significant complication after carotid revascularization and is increasingly recognized after acute stroke treatments. In this review, we discuss the epidemiology and pathophysiology of CHS, clinical presentation including ipsilateral headache, seizures, and focal neurological deficits, and radiographic presentation. We propose preventive therapies with emphasis on acute stroke post-thrombectomy hyperperfusion. RECENT FINDINGS: CHS was first described after carotid revascularization but is now also reported in patients with acute ischemic stroke...

Objective A small number of patients has been reported to develop a completely new or de novo arteriovenous malformation (AVM) after brain surgery, haemorrhage, head trauma or ischaemic stroke. The natural history of these lesions is unknown. In this review, both ruptured and unruptured de novo AVMs and their treatments were reviewed. Methods Published literature in the PubMed database citing 'de novo cerebral arteriovenous malformation' was reviewed. Additional studies were identified through reference searches in each reviewed article...

The mechanisms of injured brain that establish poststroke seizures and epilepsy are not well understood, largely because animal modeling has had limited development. The main objective of this study was to determine whether an arterial occlusion model of cortical stroke in young adult and aged rats was capable of generating either focal or generalized epileptic seizures within 2 months of lesioning. Four- and 20-month-old male Fischer 344 (F344) sham-operated controls and those lesioned by transient (3 h) unilateral middle cerebral artery (MCA) and common carotid artery (CCA) occlusion (MCA/CCAo) were studied by video-EEG recordings up to 2 months post-procedure...

BACKGROUND: Stroke is one of the leading causes of acquired epilepsy in adults. An instrument to predict whether people are at high risk of developing post-stroke seizures is not available. We aimed to develop and validate a prognostic model of late (>7 days) seizures after ischaemic stroke. METHODS: In this multivariable prediction model development and validation study, we developed the SeLECT score based on five clinical predictors in 1200 participants who had an ischaemic stroke in Switzerland using backward elimination of a multivariable Cox proportional hazards model...

BACKGROUND: Major neurologic events (MNEs) after heart transplantation (HTx) and their effect on survival have not been well described in children. In this study we aimed to characterize early MNEs (stroke, isolated seizures not from stroke and posterior reversible leukoencephalopathy [PRES] within 1 year after primary pediatric HTx) and evaluate their impact on 1-year post-HTx survival. We hypothesized that early an MNE after HTx is associated with decreased 1-year patient survival. METHODS: We performed a pediatric, single-center, retrospective analysis of 345 consecutive patients aged 0 to 22 years who underwent primary HTx during the period from November 1, 1994 to October 31, 2015...

Atrial fibrillation (AF) most frequently occurs as a consequence of multiple etiologies including valvular disease, coronary artery disease, hyperthyroidism, alcohol ingestion, and pulmonary embolism. However, on rare occasion transient AF may be a result of generalized tonic-clonic seizures (GTCS). A 33-year-old-man presented to the emergency department following GTCS in AF with rapid ventricular response. He had no previous documented history. Diagnostic evaluation including electrolytes, thyroid function, cardiac enzymes, serum and urine drug screen, and two-dimensional echocardiogram were unremarkable...

The most common forms of acquired epilepsies arise following acute brain insults such as traumatic brain injury, stroke, or central nervous system infections. Treatment is effective for only 60%-70% of patients and remains symptomatic despite decades of effort to develop epilepsy prevention therapies. Recent preclinical efforts are focused on likely primary drivers of epileptogenesis, namely inflammation, neuron loss, plasticity, and circuit reorganization. This review suggests a path to identify neuronal and molecular targets for clinical testing of specific hypotheses about epileptogenesis and its prevention or modification...

We report a patient presented with recurrent pericardial effusion caused by drug-induced systemic lupus Erythematosus (SLE) following mitral valve repair. The surgery was complicated by hemiparesis and convulsion in early postoperative period. The patient had been received carbamazepine for a paroxysmal seizure that occurred following mitral valve repair. The post operative computed tomography showed embolic stroke and its sequel (seizure) that treated with carbamazepine. In the 3rd month of follow-up, however, hemiparesis recovered by physiotherapy but carbamazepine was not discontinued as by request of neurologist...

This study evaluated the efficacy of gastrodin in combination with folate (FOL) and vitamin-B12 (V-B12) on patients with epilepsy after stroke (EAS) and its effect on high-mobility group protein B1 (HMGB-1), interleukin-1 (IL-1), and IL-6 serum levels. The clinical data of 92 EAS patients admitted for treatment between April, 2014 and March, 2016 were collected. These patients were randomly divided into control and observation groups (n=46 each) using computer software. Patients in the control group were administered only regular antiepileptic drugs, whereas observation group patients also received a combination of gastrodin, FOL and V-B12...

Brain ischemia triggers excitotoxicity and cell death, yet no neuroprotective drugs have made it to the clinic. While enhancing GABAergic signaling to counterbalance excitotoxicity has shown promise in animal models, clinical studies have failed. Blockade of GABA transporters (GATs) offers an indirect approach to increase GABA inhibition to lower the excitation threshold of neurons. Among the GATs, GAT1 is known to promote neuroprotection, while the protective role of the extrasynaptic transporters GAT3 and BGT1 is elusive...
