What is a Stroke?
A stroke is caused by a disruption of blood flow to the brain as a result of a blockage or leakage in a blood vessel. Like all organs, the brain needs oxygen and nutrients provided by blood to function properly. If the supply of blood is restricted or stopped, brain cells begin to die. The effects of a stroke vary depending on the severity of the blockage or leakage but can affect movement, speech, memory and emotions, making everyday tasks difficult. A stroke can lead to brain injury, disability and possibly death.
