STROKE PREVENTION
Knowledge of risk factors for stroke and taking appropriate measures to counter act these can play an important role in both primary and secondary prevention of stroke.
​
A stroke occurs when areas of the brain are damaged as a result of a disruption in blood supply to the brain.
Blood supply can be disrupted in two ways:
-
Blockage (thrombosis/embolism): a blood clot, or atherosclerotic plaque (fatty build up) blocks the arteries to the brain cutting off blood supply.
-
Bleed (hemorrhage): the blood vessel bursts causing bleeding into the brain tissue.
​​
Each of the following risk factors can increase your chance of a stroke:
​
Medical Risk Factors:
- Hypertension
- Diabetes Mellitus (diabetes)
- High blood Cholesterol
- Current Heart Disease
- Human Immune deficiency Virus (HIV)
​
Lifestyle factors:
- Smoking
- Being overweight
- Physical inactivity
- Poor diet
- Excessive alcohol consumption.
- Drug abuse

​
If you suspect someone is having a stroke get them to hospital as soon as possible, and preferably to a hospital with a stroke unit, because in certain cases, strokes can be reversed if the blood flow to the brain is restored before the brain tissue dies. It may be possible to reduce /remove a clot by means of medical or surgical procedures.
​
In South Africa, contact your nearest hospital in case of emergency or dial 112 from a cellphone.
