A stroke is a medical emergency that occurs when the blood supply to part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients. Brain cells begin to die in minutes, leading to permanent damage if not treated quickly.
What is a Stroke in Simple Terms?
A stroke happens when there's an interruption in the blood flow to your brain due to either a blocked artery or burst blood vessel. This sudden disruption can cause serious and potentially long-lasting effects on various functions of the body, depending on which part of the brain is affected.
