Predictors of Early Seizures After First Acute Stroke

Background and objective: There is a lack of local data regarding the frequency and predictors of early seizures after stroke. The objective of this study was to determine the frequency of early seizures after stroke and identify the predictors which lead to them after first acute stroke. Methods: This cross-sectional observational study was conducted in the Department of Neurology, Pakistan Institute of Medical Sciences, Islamabad from October 2021 to June 2022. A total of 310 consecutive eligible patients of acute stroke were recruited. Key inclusion criteria included any patient of \u3e20 years of age with confirmed diagnosis of stroke on imaging, non-traumatic, with no history of seizures in past. Data was analyzed by SPSS version 23.0. Results: The mean age of patients in the seizures group was 48.40 ± 20.9 years. Hypertension was the most common co-morbid present in 225 (76.5%) patients. Early seizures were found in 52 (16.8%) patients with 42 (80.76%) having seizures in first 24 hours of stroke (p value 0.001). On National Institute of Health Sciences Scale (NIHSS) score most patients 125 (40.3%) had moderate severity score i.e. score in between 7 to 25 (p value 0.05). Ischemic stroke was identified as the stroke variety with most of the early seizures i.e. 16 (30.76%) (p value 0.003). Conclusion: Early seizures were not infrequent after acute stroke (16.77%) in our study. Early seizures were associated with younger age, cortical region lesion, ischemic stroke, followed by cerebral venous thrombosis. Higher NIHSS score and greater disability was associated with increased incidence of early seizures
