Middle-aged adults with higher troponin levels face a 38% greater dementia risk, study finds.
A new study in the European Heart Journal finds middle-aged adults with elevated troponin levels—a sign of subtle heart damage—face a 38% higher risk of developing dementia later in life, with biological markers detectable up to 25 years before diagnosis.
Researchers tracked nearly 6,000 civil service workers for 25 years, finding that higher troponin levels correlated with faster cognitive decline and brain changes linked to memory loss.
Experts say the results underscore the strong connection between heart and brain health, suggesting that managing blood pressure, cholesterol, weight, and physical activity in midlife may help reduce dementia risk, and that troponin could become a useful early predictor.
