What to know about stroke

A stroke occurs when blood flow to the brain is interrupted, depriving brain cells of oxygen and nutrients. It is a leading cause of death and long-term disability worldwide, with millions of new cases reported each year.

Data shows that one in four adults may experience a stroke in their lifetime, highlighting its widespread impact.

Stroke-related disability has increased over the years, placing a growing burden on individuals, families and healthcare systems.

The condition is a medical emergency that requires immediate treatment to reduce the risk of severe brain damage or death.

High blood pressure remains the leading risk factor for stroke, significantly increasing the likelihood of occurrence.

Other major contributors include unhealthy lifestyle habits such as poor diet, lack of physical activity, smoking and excessive alcohol consumption.

Age, a previous stroke and underlying conditions like heart or kidney disease also raise the risk, making prevention and early management critical.
