Anxiety may increase risk of dementia, study finds | CNN

As if people with anxiety don’t have enough to worry about, a new study is adding to that list — suggesting the disorder may nearly triple the risk of developing dementia years later.

“We have known for a long time that stress increases risk for Alzheimer’s disease,” said Dr. Rudolph Tanzi, director of the McCance Center for Brain Health at Massachusetts General Hospital in Boston, who wasn’t involved in the study, via email. “This study agrees with earlier studies that therapy aimed at alleviating anxiety can help reduce risk for (Alzheimer’s disease). But, it’s the size of this study that is particularly compelling.”
