Stroke is one of the leading causes of death and long-term disability worldwide. It occurs when the blood supply to part of the brain is interrupted — either by a clot blocking an artery (ischaemic stroke, accounting for ~85% of cases) or by a blood vessel rupturing (haemorrhagic stroke). When blood flow stops, brain cells begin to die within minutes from lack of oxygen and nutrients.
Recognising a Stroke: Use FAST
Recognising the signs of stroke and calling emergency services immediately can be the difference between full recovery and permanent disability. The FAST framework makes recognition simple:
The Hidden Risk Factors
Several factors significantly increase stroke risk — and many are modifiable:
- 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 independently elevate risk; together they compound it significantly.
- 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
Stroke prevention is largely within our control. Monitor blood pressure regularly and take medications as directed. Engage in regular physical activity — walking, swimming, or any sustained aerobic movement improves cardiovascular health meaningfully. Maintain a diet low in salt and processed foods. Avoid smoking. Limit alcohol. These five interventions collectively reduce stroke risk substantially and are the foundation of any prevention strategy.
The Role of Physiotherapy in Stroke Recovery
Early physiotherapy rehabilitation — ideally beginning within 24–48 hours of a neurologically stable stroke — significantly improves functional outcomes. The brain's neuroplasticity (its ability to reorganise and form new connections) is highest in the acute and subacute phases following stroke. Intensive, task-specific movement therapy during this 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 rehabilitation team and sufficient intensity of therapy, outcomes that were once considered impossible are now achievable.
