what is a stroke?what causes strokes?how to help strokes victims or somebody who suddenly collapses of stroke?

Answer 1

Strokes can be divided into hemorrhagic (bleeding) or thrombotic (clots, emboli, etc.). A stroke is basically what happens when the oxygen supply to the brain is disrupted.

If someone collapses from a suspected stroke, the most important thing is to call an ambulance and try to prevent further injury. Lay the person down, with paralysed side down if there is paralysis, make sure the airway is clear and the patient is breathing, and provide constant reassurance (even if the person appears unconscious).

Not much you can do beyond that. Collect as much information as you can before the paramedics arrive, and don't leave until they tell you to. Eyewitness accounts are invaluable to doctors.

Hope this helps.

Answer 2

85% of strokes are caused by blood clots or cholesterol clots, interrupting the flow of blood to the brain. The other 15% are hemorrhagic, bleeding from ruptured blood vessels. If you suspect a stroke, Call 911, the sooner the symptoms are seen and treated, the better regain of function. You should get a CT scan done and clot-busting drugs administered within one hour, if possible. Time lost=function lost.
