EXPLAINER: World Stroke Day! Raising awareness for stroke prevention and action

Observed annually on October 29, World Stroke Day brings global attention to stroke prevention and awareness, aiming to reduce the high rates of disability and death associated with strokes.

This year, the theme for 2024, #GreaterThanStroke Active Challenge, harnesses the motivational energy of sports to inspire action on stroke prevention and rehabilitation.

A stroke can occur suddenly, causing life-altering consequences. Recognising symptoms early and understanding risk factors are critical to improving outcomes.

World Stroke Day serves as a reminder for individuals, families, and communities to educate themselves about strokes and take preventative steps to lessen the global impact of this serious health condition.

What is a Stroke?

According to the World Health Organization (WHO), a stroke occurs when blood flow to part of the brain is interrupted or reduced, depriving brain tissue of essential oxygen and nutrients. Within minutes, brain cells can begin to die, causing potential disability or even death.

Strokes can be classified into three types: Ischemic Stroke: Caused by a blockage that obstructs blood flow to the brain. Hemorrhagic Stroke: Occurs when a blood vessel in the brain bursts, causing bleeding.

Transient Ischemic Attack (TIA): Often called a “mini-stroke,” with temporary symptoms that signal an increased risk of future strokes.

Dr Tedros Adhanom Ghebreyesus, WHO Director-General, highlighted the global impact of strokes, stating, "Strokes are preventable and treatable, yet they continue to cause untold suffering for millions of families worldwide."

Symptoms of Stroke

Recognising the Warning Signs Identifying stroke symptoms promptly is essential to reducing the risks of mortality and long-term disability. The World Stroke Organization (WSO) emphasizes that early treatment greatly minimises brain damage and improves recovery.

A helpful way to remember stroke symptoms is the acronym F.A.S.T. Face: Is one side of the face drooping or numb? Ask the person to smile and see if it’s uneven. Arms: Is one arm weak or numb?

Ask the person to raise both arms and see if one drifts downward.

Speech: Is speech slurred or strange? Ask the person to repeat a simple sentence. Time: If any of these signs are present, call emergency services immediately. Every minute counts.

Additional symptoms include sudden confusion, trouble with vision, a severe headache without known cause, and loss of coordination or balance.

The WSO’s message is clear: “Time lost is brain lost.” Risk Factors for Stroke Stroke Risk Factors can be both modifiable and non-modifiable.

Modifiable Factors: High blood pressure, high cholesterol, diabetes, smoking, obesity, physical inactivity, and alcohol or drug use. Non-modifiable Factors: Age (particularly over 55), gender, and family history.

Preventing Stroke On World Stroke Day, WHO and WSO stress the importance of prevention, noting that up to 90% of strokes can be prevented with healthier lifestyle choices:

Exercise and Diet: Regular physical activity and a diet rich in fruits, vegetables, and lean proteins help manage weight, blood pressure, and cholesterol.

Blood Pressure and Diabetes Management: Monitoring and managing high blood pressure and diabetes are crucial.

Avoid Tobacco and Limit Alcohol: Smoking and excessive alcohol increase stroke risk. Stress Management: Reducing stress through mindfulness, exercise, or relaxation techniques can lower blood pressure.

Regular Screenings: Regular health check-ups detect risk factors like hypertension and high cholesterol early, allowing for timely interventions.

A Call to Action World Stroke Day reminds us that strokes are a preventable global health crisis.

By understanding symptoms, managing risk factors, and committing to healthy lifestyle choices, we can reduce the devastating impact of stroke.

Dr. Tedros Ghebreyesus reinforces this message, saying, “Prevention is the foundation of good health.” Let’s use this World Stroke Day to commit to greater awareness, support stroke survivors, and make strides toward a healthier world.
