Risk prediction tools that estimate future risk of heart disease and stroke may be more useful predictors of future decline in cognitive abilities, or memory and thinking, than a dementia risk score, according to a new study published in the April 2, 2013, print issue of Neurology®, the medical journal of the American Academy of Neurology.
“This is the first study that compares these risk scores with a dementia risk score to study decline in cognitive abilities 10 years later,” said Sara Kaffashian, PhD, with the French National Institute of Health and Medical Research (INSERM) in Paris, France.
The study involved 7,830 men and women with an average age of 55. Risk of heart disease and stroke (cardiovascular disease) and risk of dementia were calculated for each participant at the beginning of the study. The heart disease risk score included the following risk factors: age, blood pressure, treatment for high blood pressure, high density lipoprotein (HDL) cholesterol, total cholesterol, smoking, and diabetes. The stroke risk score included age, blood pressure, treatment for high blood pressure, diabetes, smoking, history of heart disease, and presence of cardiac arrhythmia (irregular heart beat).
