A stroke, also called a “brain attack,” occurs when a blood vessel in the brain becomes blocked with plaque, a blood clot, or other substance, or when a blood vessel in the brain bursts. Due to the fact that the human brain is not able to store its own oxygen, it depends on various blood vessels for this supply.When a brain attack takes place, the person's oxygen supply to this organ is cut off and after several minutes, brain tissue begins to die. For this reason, no one should ever ignore the signs or symptoms associated with a brain attack. Rather, the person should call 911 or if possible, get the attention of another individual who can help.
