Two main types

Ischemic strokes (85%) come from a blocked vessel; hemorrhagic strokes (15%) from a ruptured vessel. Imaging distinguishes them rapidly.

Treatment window

Thrombolysis is most effective within 4.5 hours; mechanical thrombectomy extends the window for large-vessel occlusions to 6-24 hours in selected patients.

Prevention

Blood pressure control, atrial fibrillation anticoagulation, statin therapy when indicated, smoking cessation and physical activity dramatically reduce risk.

Calling emergency services beats driving to hospital: ambulance teams pre-alert stroke units.

The words explained

Medical terms used above, in everyday language.

Blood pressure

  • They get worse quickly, or stop you doing everyday things.
