The Management of a Stroke patient occurs at three levels: Reversal of Stroke; Prevention of Stroke; and Rehabilitation of Stroke Reversal of Stroke:
A Brain Stroke results from the sudden onset of a change in the blood supply to a part of the brain.
This change could be a Block in the blood vessel, due to a clot, which then leads to Ischemia and then Infarct.
Or, this change could be due to a blood vessel in the brain rupturing and causing a “Brain Hemorrhage” a.k.a. Brain Bleed.
Strokes of the first kind – Ischemic Stroke – are potentially reversible, provided certain conditions are met.

Stroke Reversal requires treatment with Thrombolytic Therapy (Clot Buster therapy)
Prevention of Ischemic Stroke:
The underlying mechanism of an Ischemic Stroke is a source of embolism. This source is either the Heart or the Blood Vessels.
About 15% of Ischemic Strokes are due to clots arising in the heart – Cardio-embolic Strokes. The most common cause of Cardio-embolic Stroke is an enlarged (dilated) lower left chamber (Left Ventricle) of the heart, due to Coronary Artery Disease.
Another cause for cardio-embolic stroke – commoner in the Tropics – is disease of the heart valves leading to enlarged (dilated) upper left chamber (Left Atrium) of the heart – which could be Congenital or acquired/Rheumatic (Coming up: What is Rheumatic Heart Disease?)
About 85% of Ischemic Strokes are due to artery-to-artery embolism. For this to happen, some part of the inner wall of an artery has to become roughened – commonly due to Atherosclerotic Plaques Clots form on the surface of these plaques, and from these clots, small bits break of as ’emboli’ which then move into the blood stream and can get lodged into a smaller branch, leading to Ischemia and Infarct.
