Which therapy is commonly used to treat ischemic stroke within the time window?

• A. Physical therapy
• B. Anticoagulation
• C. Oxygen therapy
• D. Thrombolytic therapy with clot-busting drugs

Answer: (D)

Ischemic stroke is caused by a clot that blocks blood flow to brain tissue, so restoring perfusion as quickly as possible is the key goal within the treatment window. Thrombolytic therapy uses clot-busting drugs to dissolve that clot and reopen the blocked vessel, making it the standard acute treatment when the patient presents within the approved time frame. When given promptly and after appropriate imaging to exclude bleeding, these drugs can significantly improve outcomes by minimizing brain injury and disability. Other options don’t address the blockage directly in the acute phase. Physical therapy is rehabilitation after the event. Oxygen is used only if the patient is hypoxic and does not dissolve the clot. Anticoagulation helps prevent future clots but is not the immediate treatment for an existing clot and carries bleeding risk if started too soon after stroke.
