| Abstract: | Stroke is the third major cause of death and foremost cause of disability worldwide. Cerebrovascular stroke remains largely a clinical diagnosis. The use of biomarkers in diagnosing stroke and assessing prognosis is an emerging and rapidly evolving field. The study aimed to investigate the predictive value of neurobiochemical marker of brain damage (neuron-specific enolase NSE]) with respect to degree of disability at the time of admission and neurological worsening in acute ischemic stroke patients. We investigated 150 patients with cerebrovascular stroke who were admitted within 72 h of onset of stroke in the Department of Neurology at SAIMS. Venous blood samples were taken after admission and NSE was analyzed by solid enzyme linked immunosorbent assay using Analyzer and microplate reader from Biored: Code 680. In all patients, the neurological status was evaluated by a standardized neurological examination and the National Institutes of Health Stroke Scale on admission and on day 7. Serum NSE concentration was found to significantly correlate with both degree of disability and neurological worsening in acute ischemic stroke cases in the present study. The maximum serum NSE level within 72 h of admission was significantly higher in patients with greater degree of disability at the time of admission. Serum NSE levels were also found to be significantly elevated in patients with bad neurological outcome. Our study showed that serum NSE has high predictive value for determining severity and early neurobehavioral outcome after acute stroke. |
