Top Stroke Doctors Reveal Crucial Habits to Avoid for Lifelong Brain Health

A recent article published by HuffPost has shed new light on habits doctors warn everyone to avoid to dramatically reduce the risk of stroke — a disease that remains a silent but deadly threat worldwide, including in Thailand. Leading neurologists shared insights on seven lifestyle choices that can silently elevate stroke risk, and urge the public to make proactive changes for healthy brains and bodies throughout life. With strokes still ranking among the top causes of death and disability, preventive measures have never been more essential for Thai society.

Strokes, known medically as cerebrovascular accidents, are a leading cause of long-term disability and premature death worldwide. According to the World Stroke Organization, over 12 million strokes occur globally each year, and Thailand is no exception — the Thai Ministry of Public Health estimates tens of thousands of new stroke cases and fatalities annually (World Stroke Organization, Ministry of Public Health, Thailand). Beyond the immediate physical toll, strokes take a heavy socioeconomic cost, often leaving patients and families with lifelong care challenges.

Contrary to the belief that stroke risk is determined solely by genes or aging, researchers now agree that lifestyle is a crucial factor. According to the U.S. Centers for Disease Control and Prevention (CDC), an astonishing 80% of strokes are preventable (CDC Stroke Fact Sheet). This means that simple daily choices can make a transformative difference in stroke prevention, an insight echoed by top stroke specialists interviewed in the HuffPost feature: a vascular neurologist at the University of California, San Francisco, and the director of endovascular neurosurgery at Tulane University School of Medicine (HuffPost).

A prime message from these experts is to break free from a sedentary lifestyle. Spending too much time sitting may seem harmless, but it contributes to plaque build-up in the arteries and reduces blood vessel flexibility. “Regular physical activity helps keep your blood vessels clog-free,” noted the neurosurgery director. The specialists advise aiming for at least 30 minutes of moderate exercise, five days a week. Activities such as brisk walking, gardening, cycling, or even traditional Thai dance not only boost cardiovascular health but are accessible to people of all ages. In Thailand, where city commuting and office work are common, integrating movement into daily routines is vital.

Another critical factor emphasized is the silent danger of high blood pressure. Often called the “silent killer,” hypertension frequently presents without noticeable symptoms but significantly increases stroke risk over time. The UCSF neurologist noted, “If you took a magic wand and waved it and suddenly eliminated high blood pressure from the U.S. population, there would be 60% fewer strokes.” This urgency applies equally to Thais, where stress, high-sodium diets, and underdiagnosis have contributed to a surge in hypertension cases (Thai Hypertension Society). Regular blood pressure monitoring — even at home using affordable devices — is vital for early detection and management.

Overlooking regular health check-ups is another silent risk. Many stroke risk factors, including high cholesterol and high blood sugar, do not produce early symptoms. Preventive check-ups enable the detection and control of “cryptic” health threats before they cause irreversible harm. The Tulane director underscored this, explaining that unless routine screenings are performed, “a patient would never know that their blood pressure’s high, they wouldn’t know whether they have high cholesterol unless all of this is routinely tested or screened on a regular basis.” In Thailand, the Ministry of Public Health offers annual health checks for insured citizens and recommends midlife screening for blood pressure, cholesterol, and glucose.

Smoking remains a major modifiable stroke risk, with both foreign and Thai doctors warning against it. Smoking causes blood vessels to narrow over time and fosters artery blockages, which may suddenly cut off blood supply to the brain — the event that defines a stroke. The UCSF expert warned, “That definitely increases the risk of stroke, and heart disease, for that matter.” Although smoking rates are declining among urban Thais, recent surveys show worrying trends in youth and rural regions (Thai Health Promotion Foundation). Smoking cessation programs, counseling, and national anti-smoking campaigns are proven means to reduce individual and community risk.

Alcohol misuse is another underestimated threat. The CDC sets clear guidelines: for women, consuming over four drinks in one sitting or more than eight drinks weekly is considered excessive; for men, more than five drinks in one sitting or 15 weekly. In excess, alcohol raises blood pressure, increases the tendency for clots, and damages the brain. The UCSF neurologist stated, “There is an association between excessive alcohol use and heart disease and stroke risk.” Thailand’s culture of social drinking, particularly during festivals or in entertainment zones, can expose individuals to this elevated risk, underscoring the importance of moderation as per recommendations by the Department of Disease Control (WHO Thailand).

Dietary patterns play a central role in stroke prevention. Foods rich in saturated fats, sugars, and salt promote cardiovascular disease, while excessive salt intake is strongly linked to high blood pressure. Conversely, a plant-focused diet — described by the experts as “eat food, mostly plants, not too much” — is protective. Such a diet is well-suited to the Thai lifestyle, given the abundance of fresh fruits, vegetables, and herbs in traditional cuisine. However, increased consumption of processed foods and fast food in urban areas poses a growing concern.

Perhaps most vital of all is prompt recognition and decisive action when facing stroke symptoms. The experts reminded readers that the effectiveness of stroke treatment declines rapidly the longer a patient delays seeking help. Public health initiatives in Thailand have promoted FAST (Face, Arm, Speech, Time) recognition campaigns, urging anyone who experiences sudden facial drooping, arm weakness, or speech difficulties to go straight to a hospital without delay (Thai Red Cross Society).

Historical and cultural context further reinforces the importance of stroke prevention in Thailand. Buddhist teachings emphasize balance and moderation, which harmonizes with medical recommendations for a healthy diet, physical activity, and responsible drinking. Community-based health volunteers (อสม) — a staple of Thai rural health strategy — can help monitor blood pressure and encourage neighbors to stay active, quit smoking, and eat healthily.

Looking ahead, experts project rising stroke rates in Southeast Asia due to aging populations, urban lifestyles, and the dietary shift towards processed foods. However, this trend can be reversed through robust public health campaigns, greater access to screening, and the continued promotion of healthy behaviors (Lancet Global Health). Innovative digital health tools, such as wearable fitness trackers and blood pressure apps, may also empower more Thais to understand and control their risk.

For Thai readers, the recommendations are clear and achievable: Move your body every day, check your health with a doctor regularly, quit smoking, moderate alcohol, choose whole foods over processed snacks, watch your blood pressure, and act fast if stroke symptoms strike. Families can support one another by exercising together, preparing healthy meals, and sharing information learned in this report with elderly relatives, who are at highest risk.

Collectively, these small steps could yield big rewards, preventing strokes and safeguarding brain health for all generations of Thais. Further information on stroke prevention and management is available from the Ministry of Public Health’s official portal and local hospitals, where free community screening events are often organized.

A growing body of new research is turning long-held assumptions about “mini-strokes” upside down, revealing that the effects of transient ischemic attacks (TIAs) may linger far longer than previously thought. Once regarded as brief episodes with symptoms that disappear within a day, these transient strokes are now understood to pose significant long-term health risks—including persistent fatigue, cognitive decline, and an elevated risk of subsequent strokes and cardiovascular events. As experts warn against taking a TIA lightly, the implications for Thai patients and the healthcare system are profound, demanding heightened awareness, rapid intervention, and ongoing support.
