Older adults with atrial cardiopathy, even before symptoms develop, may have up to 35% higher risk for dementia, new research suggests. MedTwitter
The risk of dementia was even stronger when the researchers defined cardiopathy by at least two biomarkers instead of one .Clifford Kavinsky, MD, PhD, head of the Comprehensive Stroke and Cardiology Clinic at Rush University Medical Center in Chicago, Illinois, toldthat much more research would need to be done to show convincingly that atrial cardiopathy causes dementia.
He said he also wonders whether the results eliminated all patients with atrial fibrillation, a point the authors acknowledge as well. There is broad understanding that preventing heart disease is important for a wide array of reasons, Kavinsky noted, and one of the reasons is cognitive deterioration.
The study amplifies the need to shift to prevention with heart disease in general, and more specifically in atrial dysfunction, Kavinsky said, noting a lot of atrial dysfunction is mediated by underlyingResearchers evaluated cognitive decline in all participants with a comprehensive array of neuropsychological tests and interviewed some of the patients.
