New study examines Alzheimer’s disease images and molecular biomarkers
May. 7, 2020—Alzheimer’s disease (AD) involves distinctive wasting away of certain brain regions, such that medical imaging of these regions can distinguish the disease from other subtypes of dementia.
Small vessel disease MRI marker linked to worse cognitive health in older adults
Mar. 21, 2019—Enlarged perivascular spaces, which are commonly seen on brain MRIs in older adults, have important associations with worse cognitive performance, particularly information processing speed and executive function, according to a new study that challenges historical consideration that perivascular spaces are a harmless imaging marker.
Probing the pathology of impaired cognition
Oct. 25, 2018—Detecting the neuropathology underlying cognitive impairment by lead to new targeted therapies.
Study links aortic stiffness with lower cerebral blood flow
Aug. 30, 2018—Greater aortic stiffness is related to lower cerebral blood flow, especially among individuals with increased genetic predisposition to Alzheimer’s disease, according to research from Vanderbilt University Medical Center.
Research links heart function to brain’s memory center
Nov. 8, 2017—Research by a team of Vanderbilt University Medical Center (VUMC) scientists suggests that older people whose hearts pump less blood have blood flow reductions in the temporal lobe regions of the brain, where Alzheimer’s pathology first begins.
Study shows poor heart function could be major Alzheimer’s disease risk
Mar. 3, 2015—A healthier heart could prevent Alzheimer’s disease, according to new research at Vanderbilt University Medical Center.
Cognitive complaints, Alzheimer’s risk studied
Aug. 1, 2013—A study of cognitive complaints in older adults showed that memory concerns from both the patient and an informant was most predictive of converting to Alzheimer’s disease or dementia within three years.
