Strokes are well-established as a very time sensitive condition. The standard mnemonic device for stroke detection is F.A.S.T.

Face drooping

Arm weakness

Speech problems

Time to go to the ER

If you or someone you see is having symptoms, rushing to medical care is the best way to stay alive and minimize impacts of a stroke. This new treatment (EVT) as well as older treatments (TPA) all work to remove the source of occlusion that prevents oxygen from reaching parts of the brain.
