Signs of Aging May Be Linked to Undetected Blocked Brain Blood Vessels, Rush University Medical Center Study

Many common signs of aging, such as shaking hands, stooped posture and walking slower, may be due to tiny blocked vessels in the brain that can't be detected by current technology. In a study reported in Stroke: Journal of the American Heart Association, researchers from Rush University Medical Center, Chicago, examined brain autopsies of older people and found: Microscopic lesions or infarcts — too small to be detected using brain imaging — were in 30 percent of the brains of people who had no diagnosed brain disease or stroke.
