New guidelines suggest that most strokes could be prevented with proactive measures, providing hope for both individuals and healthcare providers in reducing this serious health risk.

Stroke was the fourth leading cause of death in the U.S. in 2023, according to the Centers for Disease Control and Prevention, with over half a million Americans affected annually. The American Stroke Association, part of the American Heart Association, has released the first updated stroke prevention guidelines in a decade, emphasizing the role of healthy habits and early risk identification. These guidelines reflect deeper insights into stroke causes and introduce new medications aimed at prevention.

Encouragingly, the same lifestyle changes that lower stroke risk also reduce the risk for other chronic conditions. Following a healthy diet, staying physically active, and avoiding smoking are central to preventing strokes. Dr. Sean Duke, a stroke specialist at the University of Mississippi Medical Center, highlighted societal challenges that can make healthy living difficult, like excessive screen time and the widespread availability of inexpensive, unhealthy food options.

Understanding Strokes

A stroke occurs when blood flow to the brain is disrupted, either by a blocked artery or a burst blood vessel. This deprivation of oxygen can lead to lasting brain damage, affecting abilities such as speech, movement, and even basic thinking.

The Role of Diet in Stroke Prevention

Diet plays a key role in managing factors that raise stroke risk, such as high cholesterol, elevated blood sugar, and obesity. The American Heart Association recommends a Mediterranean-style diet rich in fruits, vegetables, whole grains, and olive oil, with limited red meat and other saturated fats. They also advise cutting back on processed foods and sugary drinks, which can help maintain a healthy weight.

Physical Activity as a Preventative Measure

Regular movement, even just 10 minutes a day, can significantly reduce stroke risk, says Dr. Cheryl Bushnell, a neurologist at Wake Forest University School of Medicine. Exercise helps lower blood pressure, a primary risk factor for stroke. The American Heart Association recommends at least 150 minutes of moderate aerobic exercise weekly or 75 minutes of vigorous activity. Whether through a gym workout or a brisk neighborhood walk, consistency is key.

New Medications for Weight Management

Obesity is another major stroke risk factor. While diet and exercise remain foundational, a new class of weight-loss medications, like Ozempic, Wegovy, Mounjaro, and Zepbound, offer additional options for those with obesity or diabetes. However, as Dr. Fadi Nahab from Emory University Hospital points out, these medications are not replacements for a healthy diet and regular exercise.

Expanded Screening for Stroke Risks

For the first time, the new guidelines advise that doctors consider factors beyond traditional health risks, such as social and economic barriers, gender, and race, which can impact stroke risk. For instance, Black adults in the U.S. face nearly double the risk of a first stroke compared to white adults. Dr. Bushnell noted that difficulties like lack of health insurance, limited access to healthcare, and transportation challenges can hinder preventive care. Doctors are encouraged to connect patients with affordable resources for healthcare, nutrition, and physical activity.

Additionally, the guidelines recommend screening women for specific risks, including high blood pressure during pregnancy and early menopause.

Recognizing and Acting on Stroke Symptoms

If a stroke does occur, early intervention is crucial. Watch for common symptoms: face drooping, arm weakness, and speech difficulties. Remember the acronym "FAST" – Face, Arm, Speech, and Time. Acting quickly can limit brain damage, so if you suspect a stroke, call 911 immediately.

With lifestyle adjustments and these new prevention strategies, many strokes could be avoided, offering hope for individuals and a blueprint for healthcare providers.
