Stroke is a medical emergency and every 40 seconds, someone in the country suffers a stroke, and every four minutes, someone loses their life to it. This year, World Stroke Day highlights the transformative theme, “#GreaterThan Stroke Active Challenge,” a call to empower communities around the world to embrace sports and physical activity as a vital force in stroke prevention and rehabilitation. With stroke remaining one of the leading causes of death and long-term disability, this campaign underscores how an active lifestyle is not only a preventive tool but also an aid to recovery, empowering people to push beyond the limitations of stroke.
By bringing attention to the benefits of physical activity in managing stroke risk and supporting recovery, this year’s World Stroke Day encourages individuals, families, and communities to come together to address stroke proactively.
Understanding Stroke: The Importance of Immediate Action
A stroke occurs when blood flow to a part of the brain is blocked, either by a clot in the case of an ischemic stroke or by a ruptured blood vessel, causing a hemorrhagic stroke. This interruption deprives brain cells of oxygen and nutrients, leading to cell death within minutes. As stroke attacks brain tissue, it can result in physical disabilities, speech and memory problems, and other long-lasting effects. The severity depends on the extent and location of brain damage, but timely intervention is crucial in reducing the chances of severe disability or death.
Raising awareness among the public about the acronym – “FAST” Face drooping, Arm weakness, Speech difficulty, and Time to call emergency services—can save lives. Knowing these signs helps individuals take swift action and improves the chances of timely treatment.
Physical Activity as a Key Player in Stroke Prevention
Stroke is often preventable and that lifestyle choices play a major role in reducing one’s risk. According to the American Heart Association, physical activity can lower the risk of high blood pressure, high cholesterol, diabetes, and obesity—all major contributors to stroke risk. Regular activity improves cardiovascular health by enhancing blood flow, lowering inflammation, and improving the function of blood vessels.
For those seeking to prevent stroke, aiming for at least 150 minutes of moderate-intensity exercise per week can significantly reduce risk. Activities like walking, swimming, cycling, and dancing are not only enjoyable but effective in keeping the body active. Strengthening the heart and maintaining a healthy weight have shown to be crucial factors in lowering stroke risk. But beyond these well-known benefits, sports and physical activities provide a sense of community, accountability, and motivation, helping people make physical activity a sustainable part of their lives.
The Role of Exercise in Stroke
Rehabilitation
Exercise is not only preventive but a rehabilitative tool as well. For stroke survivors, engaging in movement aids in the process of neuroplasticity, the brain’s ability to reorganize itself by forming new neural connections. Physical activity helps survivors regain mobility, strength, and confidence. Rehabilitation through exercise enhances brain function by improving blood flow to affected areas, encouraging new pathways to form and aiding the recovery of skills lost to stroke.
Rehabilitation exercises focus on controlled movement, balance, and strength training. For example, hand exercises or leg lifts can help with regaining the strength needed for daily tasks, while aerobic exercises like walking or stationary biking can improve cardiovascular health and boost mood. Simple balance exercises can also make a world of difference for survivors facing mobility challenges, and gentle yoga has been shown to reduce stress and improve flexibility. Joining a group exercise program or working with physical therapists trained in stroke recovery further amplifies these benefits, providing stroke survivors with structured and supportive environments to rebuild strength and independence.
Traditionally, stroke treatment windows were narrow, limited to 4.5 hours for intravenous thrombolysis and six hours for mechanical thrombectomy, a minimally invasive procedure to physically remove clots. This constrained time frame left many patients who couldn’t access immediate care or who experienced strokes during sleep without critical treatment options. However, recent advancements in medical science have extended the treatment window for ischemic stroke to up to 24 hours, offering new hope to patients who would otherwise be beyond reach.
Advanced imaging tools, such as perfusion CT and MRI, can now identify “penumbra”—the brain tissue that is still viable but at risk of irreversible damage. This allows medical professionals to assess which patients could benefit from treatment, even if they arrive at the hospital well after traditional timeframes. Mechanical thrombectomy, a minimally invasive procedure where doctors use a stent retriever to remove a clot, has shown effectiveness up to 24 hours after stroke onset in certain patients. This breakthrough has significantly improved stroke care, offering a new chance for recovery and a reduced risk of long-term disability for patients who might have otherwise been considered ineligible for treatment.
Yatharth Super Specialty Hospital has recently upgraded its neurosciences Department, with a full team of Senior Neurologists, Neurosurgeons, trained Spine surgeon, Neuro Intensivists taken on board, who offer a wide range of specialised Neurological, surgical, neuro intervention, and minimally invasive Surgery and Neuro critical care in this region. With the launch of its dedicated stroke clinic, the Hospital has become a 24X7 stroke ready centre.
