A Review on Stroke’s Pathophysiology, Associated Risk Factors, and Management

Abstract

Background: Stroke is a medical disorder defined by focal neurological deficits caused by vascular impairment (hemorrhage or infarction) in the CNS (Central Nervous System). Currently the second biggest cause of morbidity worldwide, strokes continue to be a deadly disease. Objective: This review aimed to elucidate the stroke’s pathophysiology, both changeable and unchangeable risk factors associated with stroke, including prevention of stroke, its diagnosis, as well as treatment. Methods: The articles were collected involving the research on stroke with the help of different sources, like PubMed, Science Direct, and Google. Many manuscripts were collected and analyzed, and the relevant ones were considered for the present manuscript. Results: A brain CT scan has been found to be the first step in the management of Cerebrovascular Accident (CVA) in order to distinguish between ischemic and hemorrhagic stroke types. Beyond stroke classification, imaging has been observed to serve as a powerful tool for ruling out alternative diagnoses, predicting stroke outcomes, and facilitating appropriate treatment planning. Conclusion: Stroke is the second foremost cause of death as well as disability worldwide, leading to substantial economic losses. Therefore, better treatment and improved management after stroke are a global health priority. Modifying risk factors can decrease the chances of occurrence of stroke. Also, correct diagnosis should be done to diagnose the presence of stroke and its type. Proper treatment should be provided, like perfusion, glucose management, antiplatelet therapy, antihypertensive therapy, stem cell therapy, neural response and rehabilitation, increased awareness, lifestyle changes, stress management, etc. Exercise can also help positively to reduce the chances of stroke.
