Stroke (CVA)

Two ways the brain loses its blood flow · Week 5
A stroke is a sudden loss of blood flow to part of the brain. It happens in two ways. In ischemic stroke, a clot blocks a vessel. That is about 87% of all strokes. In hemorrhagic stroke, a vessel ruptures and bleeds. That is the other 13% or so. Click each one.

Watch the vessel. Is it blocked, so no blood gets past? Or burst, so blood leaks into the brain?

What is going on

Spot a stroke with FAST: Face drooping, Arm weakness on one side, Speech change, Time to call. A sudden severe "worst headache" with vomiting and loss of consciousness points to hemorrhagic. Bell's palsy droops the face too. But it hits only the face (CN 7). There is no arm or leg weakness, and no trouble understanding speech.
