What is the treatment time window for a stroke?

The treatment window depends on the type of stroke:

• Clot-busting medication (tPA):
  
  • Best within 3 hours
    
  • In some cases, up to 4.5 hours
    
• Mechanical thrombectomy:
  
  • Typically within 6 hours
    
  • Up to 24 hours for select patients with advanced imaging
    

Missing these windows can significantly worsen the outcome.
