Erythritol May Weaken Brain’s Shield, Linked to Stroke Risk in Lab Study

A laboratory study found that erythritol can damage brain endothelial cells by lowering nitric oxide, raising endothelin-1 and reactive oxygen species, and reducing tissue plasminogen activator, which together may weaken the blood-brain barrier and help explain links between higher erythritol levels and stroke risk. The work was done in cell cultures, not humans, so results must be interpreted with caution and more clinical research is needed; researchers also urge monitoring non-nutritive sweetener consumption.

Shingles: A Painful Hidden Risk Doctors Urge Vaccination Against

Shingles (reactivation of the varicella zoster virus) is not a mild illness for many: it can cause severe acute pain, long-lasting nerve pain (PHN), and increases the risk of stroke in the following year; antiviral treatment works best within 72 hours, yet vaccination rates remain low in the US and UK, leaving millions exposed and underscoring the need for greater awareness and uptake.

Erythritol Shown in Lab to Impair Brain Vessels, Potentially Elevating Stroke Risk

New lab findings from the University of Colorado Boulder suggest erythritol, a widely used sugar substitute, may impair brain microvascular endothelial cells by lowering nitric oxide, raising vasoconstrictors, reducing clot-busting t-PA, and boosting reactive oxygen species, potentially increasing stroke risk at typical intake; the work is cellular and not yet proven in people, though epidemiological data have linked higher erythritol levels with heart attack or stroke, so monitoring intake and checking labels is advised.

Amphetamines May Triple Stroke Risk in Under-55s, Cambridge Study Finds

Amphetamines May Triple Stroke Risk in Under-55s, Cambridge Study Finds

A Cambridge-led systematic review of eight studies and over 100 million individuals links recreational use of amphetamine, cocaine, and cannabis to higher stroke risk, with amphetamines showing the strongest association and under-55 users facing a nearly threefold increase. Cocaine also doubles risk, cannabis raises risk modestly (especially for ischemic stroke), while opioids show no clear link. Genetic analyses support a causal relationship for some stroke types, but many findings rely on self-reported data and can be influenced by confounding factors; results vary by age and stroke type, and further research is needed.

Mediterranean Diet Linked to Lower Stroke Risk, Including Bleeding Strokes, in a 20-Year Study

A long-term study of more than 100,000 women over about 21 years found that closer adherence to a Mediterranean-style diet—rich in fruits, vegetables, beans, fish and olive oil—was linked to an 18% lower risk of any stroke, with a 16% reduction for ischemic (clot-related) strokes and a striking 25% lower risk of hemorrhagic (brain-bleeding) strokes. The association held after adjusting for smoking, physical activity and blood pressure, suggesting diet is linked to better brain health, though causality can’t be proven.

Rising Stroke Cases Among Young Adults Highlight Urgency of Early Detection and Hypertension Management

On World Stroke Day 2025, Chennai cardiologist Dr. Babu Ezhumalai emphasizes the dangers of resistant hypertension, a silent form of high blood pressure that increases stroke risk by 14%, and advocates for regular monitoring, lifestyle changes, and innovative treatments like renal denervation to prevent serious health consequences.
