Stroke - Symptoms, Causes & Treatment
A stroke occurs when blood supply to part of the brain is interrupted or reduced, depriving brain tissue of oxygen and nutrients. Brain cells begin to die within minutes.
Overview
Stroke is a leading cause of death and disability worldwide. India has a stroke prevalence of approximately 84-262 per 100,000 population, and the incidence is rising.
Stroke is a medical emergency. Fast treatment (within the golden hour) can minimize brain damage and potential complications. Knowing the signs of stroke can save lives.
