The so-called “longevity gene” may do more than add years to your life. It may also help stave off age-related cognitive decline, and this discovery is paving the way for new drugs to treat Alzheimer’s disease, a study shows.
The longevity gene is a variant of the cholesteryl ester transfer protein (CETP) gene, which was discovered in 2003. This variant has been shown to improve cholesterol levels by increasing HDL “good” cholesterol and regulating the size of cholesterol particles. As a result, it has been linked to longevity and lower heart disease risk, but how or if this variant affects the cognitive decline that is known to occur with aging was not known — until now.
