Abstract
Abstract
Background
Available data collected from patients of different types of acute cerebrovascular strokes can detect risk factors, clinical data (including semiology of seizures), EEG findings and functional outcome of these patients. Stroke, both ischemic and hemorrhagic, has been considered an essential cause of epilepsy, especially in the elderly. Complications of acute stroke during the early days after the insult determine the ultimate outcome of events. The aim of this study is to determine the clinical and neurophysiological characteristics of stroke patients with or without clinical evident fits for early detection and better management.
Results
The brain imaging of the cases group who developed seizures showed that 50% of the cases have arterial ischemic infarction, 30% venous infarction, 6.67% ischemic infarction with haemorrhagic transformation, 6.67% intracerebral haemorrhage and 6.67% have subarachnoid haemorrhage. Based on the 2017 ILAE criteria, 43.33% of the patients developed focal to bilateral tonic clonic seizures, 33.33% developed focal aware seizures, 16.67% of the patients developed generalized tonic clonic seizures and 6.67% of the patient developed status epilepticus. EEG findings of the group of patients who developed seizures showed, focal slowing in 46.67%, focal epileptiform activity in 13.33%, focal activity with secondary generalization in 10%, PLEDS in 6.67%, generalized epileptiform activity in 6.67%, generalized slowing in 6.67% and normal EEG in 10% of the patients. Non convulsive status was found in 2 patients (6.67%) of the group with altered mental status. There was no PLEDS in EEG of group of patients without clinical seizures. This study did not find age and sex differences in patients with and without seizures. In addition, it was found that there was no statistically significant difference between the three groups as regard history of diabetes mellitus, hypertension, heart diseases, atrial fibrillation, carotid stenosis and collagen diseases. There was no significant relationship between seizures and early treatment with Rtpa and thrombectomy.
Conclusions
Focal to bilateral tonic clonic and focal aware seizures were the most prevalent type of early onset seizures after stroke, followed by generalized tonic clonic seizures and status epilepticus. Most EEG findings in this study were focal slowing, focal epileptiform activities, generalized epileptiform activities and PLEDS.

Abstract
Objective To investigate the frequency and clinical characteristics of ischemic stroke patients with early seizures, especially with cortical involvement contralateral to their focal seizures. Methods We retrospectively studied patients with ischemic stroke admitted to our hospital. We compared the clinical characteristics of patients with and without early seizures (occurring within seven days of the stroke onset). In addition, we divided the patients with early focal seizures into two groups (patients with and without cortical involvement of a recent infarct contralateral to their focal seizure) and compared the clinical characteristics of the groups. Results Of the 5,806 patients with ischemic stroke, 65 (1.2%) were diagnosed with early seizures. A history of ischemic stroke (odds ratio [OR] 1.71), a history of seizures (OR 27.58), and a National Institutes of Health Stroke Scale score on admission (OR 1.07) were significant and independent factors associated with the presence of early seizures. Of these 65 patients, 56 had focal seizures, while the others had generalized or undetermined seizures. Cortical involvement of a recent infarct contralateral to their focal seizures was observed in 24 of these 56 patients (43%). Glucose and hemoglobin A1c levels were significantly higher in patients with cortical involvement of a recent infarct contralateral to their focal seizures than in those with infarcts in other regions. Conclusion These findings suggest that recent infarcts play a role as systemic causes of acute symptomatic seizures as well as an epileptogenic lesion in ischemic stroke patients with early focal seizures.

Abstract
BACKGROUND Early seizures have been recognized as serious complications of ischemic strokes where the data are limited among Lebanese patients. This study aimed to assess the incidence and risk factors of early seizures postischemic stroke and to determine the effect of early seizures on functional outcome among Lebanese stroke patients. METHODS This was a retrospective observational study conducted between January 2017 and March 2020 on patients with acute ischemic strokes at two tertiary hospitals in Lebanon. Data were collected from patients' medical records at each site through a well-designed data collection sheet. Early seizures were defined as seizures occurring within 7 days after acute stroke. Functional outcome was assessed at discharge, according to modified Rankin scale (mRS). RESULTS Of 140 enrolled patients, early seizure developed in 12 patients (8.6%) with mean age of 68.42 ± 9.89 years and 8 (67%) were females. Independent risk factors for early seizure development were female gender and cortical involvement. Moreover, early seizure development was not associated with higher disability and mortality at hospital discharge. CONCLUSION The findings of the study highlight that early seizures occurred more commonly in patients with cortical involvement and female gender. In addition, early seizures did not impair functional outcome in our study, however; further studies are needed to predict patients at risk of early seizure so that appropriate prevention and treatment strategies can be implemented promptly.
