7 Stroke Signs, Symptoms, Warning Signs, and Treatments

Stroke definition and facts

  • A stroke occurs when part of the brain loses its blood supply and stops working. This causes the part of the body that the injured brain controls to stop working.
  • A stroke also is called a cerebrovascular accident, CVA, or “brain attack.”
  • The types of strokes include:
    • Ischemic stroke (part of the brain loses blood flow)
    • Hemorrhagic stroke (bleeding occurs within the brain)
  • Transient ischemic attack, TIA, or mini stroke (The stroke symptoms resolve within minutes, but may take up to 24 hours on their own without treatment. This is a warning sign that a stroke may occur in the near future.)
  • A stroke is a medical emergency. The affected individual, family, friends, or bystanders need to call 9-1-1 (activate EMS) to access emergency care.
