Prevent Strokes Through Lifestyle Changes and Early Intervention

Stroke is a leading cause of death and disability in the U.S., but new guidelines from the American Stroke Association (ASA) suggest that up to 80% of strokes could be prevented with healthier lifestyle choices and better risk management. According to the Centers for Disease Control and Prevention (CDC), stroke was the fourth leading cause of death in the U.S. in 2023, with over 500,000 Americans affected each year. The updated ASA stroke prevention guidelines, the first in a decade, offer a hopeful outlook by emphasizing diet, exercise, and early identification of risk factors to significantly reduce stroke risk.

The importance of lifestyle changes

A stroke occurs when blood flow to the brain is blocked or when a blood vessel bursts, depriving the brain of oxygen and causing brain damage. Managing risk factors such as high cholesterol, high blood pressure, obesity, and high blood sugar is key to reducing stroke risk, and these can be controlled through lifestyle changes like diet and exercise.

The ASA recommends a Mediterranean-style diet, which includes fruits, vegetables, whole grains, and healthy fats like olive oil. This diet has been shown to lower cholesterol and support heart health. It also advises limiting red meat and saturated fats, replacing them with lean proteins like fish, poultry, beans, and nuts. Reducing processed foods and sugary drinks can help control weight and blood sugar levels.

Regular physical activity is another crucial factor in stroke prevention. Dr. Cheryl Bushnell, a neurologist at Wake Forest University, emphasizes that even a small amount of daily exercise can help reduce stroke risk. Walking just 10 minutes a day can help control blood pressure, a key stroke risk factor. For optimal protection, the ASA recommends at least 150 minutes of moderate aerobic exercise or 75 minutes of vigorous activity per week.

New medications and risk screening

In addition to lifestyle changes, new medications are now recommended for reducing stroke risk. The updated guidelines suggest that doctors consider prescribing weight-loss drugs, such as Ozempic, Wegovy, Mounjaro, and Zepbound, for patients with obesity or diabetes. These medications can help patients lose weight, which in turn lowers stroke risk. However, experts stress that these drugs should complement, not replace, healthy habits like diet and exercise.

Another important update in the guidelines is the recommendation for doctors to screen for additional factors that could increase stroke risk, such as sex, gender, and socioeconomic factors. For instance, Black adults have nearly twice the stroke risk of white adults in the U.S., according to the CDC. Socioeconomic barriers like lack of health insurance or transportation issues can also prevent people from accessing healthcare, leading to higher stroke risk. Dr. Bushnell highlights that doctors can guide patients to low-cost healthcare resources and provide advice on affordable ways to stay active.

The importance of early detection

Early detection is vital in minimizing stroke damage. The guidelines emphasize recognizing stroke symptoms quickly using the acronym FAST:

    F for face: Is one side of the face drooping or numb?

    A for arm: Is one arm weak or numb?

    S for speech: Is speech slurred or hard to understand?

    T for time: Time is critical—call 911 immediately.

The faster a stroke is recognized and treated, the less brain damage occurs. If you or someone you know is showing stroke symptoms, seek medical help immediately.

The new stroke prevention guidelines offer a roadmap for significantly reducing stroke risk through lifestyle changes, early screening, and the use of new medications. By embracing healthier habits, managing risk factors, and taking swift action when symptoms arise, the risk of stroke can be greatly diminished. Healthcare providers are now better equipped to help patients reduce their risk and improve their overall health, making early detection and intervention critical in saving lives and improving outcomes.
