Stroke is a medical condition in which blood supply is severely reduced to parts of the brain resulting in cell death. A stroke occurs when a blood vessel in the brain ruptures and bleeds, or when there’s a blockage in the blood supply to the brain. The rupture or blockage prevents blood and oxygen from reaching the brain’s tissues. Without oxygen, brain cells and tissue become damaged and begin to die within minutes. According to the Centers for Disease Control and Prevention (CDC)Trusted Source, stroke is a leading cause of death in the United States. Every year, more than 795,000 U.S. people have a stroke. There are three primary types of strokes:
Transient ischemic attack (TIA) involves a blood clot that typically reverses on its own.
Ischemic stroke involves a blockage caused by either a clot or plaque in the artery. The symptoms and complications of ischemic stroke can last longer than those of a TIA, or may become permanent.
Hemorrhagic stroke is caused by either a burst or leaking blood vessel that seeps into the brain.
Stroke symptoms can include: ,paralysis numbness or weakness in the arm, face, and leg, especially on one side of the body, trouble speaking or understanding others, slurred speech,confusion, disorientation, or lack of responsiveness, sudden behavioral changes, especially increased agitation, vision problems, such as trouble seeing in one or both eyes with vision blackened or blurred, or double vision, trouble walking, loss of balance or coordination, dizziness, severe, sudden headache with an unknown cause, seizures, nausea or vomiting
Proper medical evaluation and prompt treatment are vital to recovering from a stroke. According to the American Heart Association and American Stroke Association, “Time lost is brain lost.”
