Small study reveals association between uncontrolled hypertension, Alzheimer's.

The Dallas Morning News (3/19, Churnin, 430K) reports that a new study "shows a link between uncontrolled hypertension and" Alzheimer's disease. Texas researchers conducted "a study of the aging brain in 147 healthy participants, ages 30-89, funded by the National Institute on Aging, measuring plaque and blood pressure at each visit. One of the most revealing findings showed that unmedicated, hypertensive adults who carried a genetic risk factor for Alzheimer's disease showed much higher plaque levels than all other groups." The study will appear in an upcoming issue of JAMA Neurology.
