What are some developments in the treatment of acute stroke?

Time is essential. It is most important to seek treatment for sudden changes in the ability to move, sense, or think. If a stroke is treated in first few hours, a great improvement in outcome may be possible. If you wait even a few hours to see if if gets better, the chances of improved recovery are greatly lessened.
Clot busters. If a stroke patient can get to the emergency room within 4 hours, tpa (alteplase) can be given by vein in hopes of breaking up the clot blocking the brain artery. If the patient gets there before 6 to 8 hours, we can place a catheter within the artery in the brain and frequently be able to break up the clot that way. It is riskier, however.
