Stroke is one of the leading causes of death and long-term disability worldwide. It happens when the blood supply to part of the brain is cut off: usually a clot blocking an artery (ischaemic stroke, roughly 85% of cases), sometimes a ruptured blood vessel (haemorrhagic stroke). Once blood flow stops, brain cells start dying within minutes from lack of oxygen and nutrients.
Recognising a Stroke: Use FAST
Stroke is one emergency where bystanders matter as much as doctors. The FAST check takes under a minute, and anyone can do it:
What Raises the Risk
Several factors raise stroke risk substantially, and the important ones can be changed:
- High blood pressure: Hypertension is the single most significant modifiable risk factor for stroke. Regular monitoring and management are essential.
- Smoking: Tobacco chemicals damage blood vessel walls and accelerate clot formation.
- Obesity and physical inactivity: both raise risk on their own; together they compound it.
- Unhealthy diet: High salt, saturated fat, and cholesterol intake drives the hypertension and atherosclerosis that underlie most strokes.
- Excessive alcohol: Raises blood pressure and increases haemorrhagic stroke risk.
Prevention: Practical Steps
Most stroke prevention is unglamorous and entirely within reach. Keep blood pressure checked and take prescribed medication. Move regularly: walking, swimming, any sustained aerobic activity. Eat less salt and fewer processed foods. Do not smoke. Drink less. These five things, done boringly and consistently, cut stroke risk more than anything else available.
The Role of Physiotherapy in Stroke Recovery
Early physiotherapy rehabilitation, ideally beginning within 24–48 hours once a stroke is neurologically stable, significantly improves functional outcomes. Neuroplasticity (the brain's ability to reorganise and form new connections) is highest in the acute and subacute phases after stroke, so intensive, task-specific movement therapy in that window drives the greatest recovery.
Physiotherapy after stroke addresses mobility, balance, upper limb function, gait, and activities of daily living. The goal is functional independence, and with the right team and enough intensity of therapy, outcomes once considered impossible are now achievable.
"A stroke is the crisis. Everything after it is the recovery: early, intensive rehabilitation, with the family involved, gives the best possible outcome."
