What is a stroke?

Related resource areas: Family Caregiving

A stroke happens when blood cannot flow to a part of the brain. When the brain does not get the oxygen and nutrients it needs from the blood, its cells are damaged or begin to die. If brain cells are only damaged, they sometimes can be repaired. But brain cells that have died cannot be brought back to life.
