Live Long and Well with Dr. Bobby

Send us a textWe often hear about heart disease prevention, but stroke—a condition nearly as common and often more disabling—gets far less attention. In this episode, Dr. Bobby is joined by cardiologist Dr. Anthony Pearson to uncover what science really says about stroke prevention, the distinct types of strokes, and what practical steps you can take today to lower your risk.Together, they explore the two major types of stroke—ischemic and hemorrhagic—and explain why strokes caused by clots or vessel rupture can have very different causes and consequences. The data shows nearly 800,000 Americans experience strokes annually, and about half of survivors live with long-term disability (CDC; NIH). Yet most of us are unaware of the modifiable risk factors that account for up to 90% of stroke risk (INTERSTROKE Study).Dr. Pearson emphasizes the number one culprit: high blood pressure. It triples individual risk and contributes to half of all strokes, with randomized trials like SPRINT showing that aggressive control reduces both stroke and mortality (SPRINT Study). Both doctors also discuss physical activity—while Dr. Bobby cites strong associations between exercise and reduced stroke risk (BMJ Review), Dr. Pearson cautions that current evidence is largely observational and inconclusive.They also explore the role of lipid levels, citing that high ApoB or LDL may increase risk in strokes caused by carotid atherosclerosis, but not necessarily in cardioembolic strokes. Dietary improvements, particularly following a Mediterranean-style diet, have shown benefits, including reduced stroke risk in randomized trials like PREDIMED.Beyond traditional risk factors, they also explore loneliness as a newer area of concern. A recent study linked persistent loneliness in adults over 50 to a 50% increased stroke risk (Lancet eClinicalMedicine), highlighting the complex social and behavioral factors at play.Dr. Pearson discusses atrial fibrillation (AFib) and why it’s a key cause of cardioembolic strokes—especially relevant given that wearables like Apple Watch now help detect AFib early. They also touch on controversial screening approaches, warning against routine carotid ultrasounds and unwarranted treatment of asymptomatic brain aneurysms.Importantly, Dr. Bobby highlights the signs of stroke—sudden weakness, numbness, speech difficulties, or confusion—and urges immediate ER visits to enable timely treatment like thrombolysis, ideally within four hours of symptom onset.As always, they wrap by challenging popular myths. Dr. Pearson explains why aspirin, once widely promoted for primary prevention, is no longer recommended due to increased bleeding risk, especially into the brain. He also debunks the idea that supplements like fish oil or B vitamins help prevent strokes, noting no benefit in recent large trials.Takeaways:Know your blood pressure and cholesterol levels—and treat them if needed. These remain the top modifiable risks for stroke.Prioritize physical activity, even if trial data is imperfect—it benefits vascular health broadly and may reduce stroke risk.Stay socially connected: chronic loneliness has emerging links to stroke risk, highlighting that prevention isn't just physical—it's relational.To continue learning how to live long and well, visit drbobbylivelongandwell.com.
