The American Heart Association recommends a cholesterol level of less than 200 for healthy adults - levels over 240 double the risk of coronary heart disease. New research links high cholesterol and dementia, according to UTMB’s Norbert Herzog and David Niesel in this week’s installment of Medical Discovery News. The link between cholesterol levels and dementia was established after reviewing a 40-year history of almost 10,000 people. The study found that people in their 40s whose cholesterol was greater than 240 had a 66 percent increased risk for dementia later in life. Those whose cholesterol was moderately elevated between 200 and 240 had a 52 percent increased risk for dementia later in life. MDN airs locally at 10 a.m. Saturday on KUHF.
