Genetic Risk Factor for Alzheimer’s Disease Impacts the Blood Brain Barrier

The most common genetic risk factor for Alzheimer’s disease (AD) disrupts the blood brain barrier, impeding oxygen and nutrient flow to the brain and exposing the brain to systemic toxins, according to a recent investigation led by scientists from the University of Rochester Center for Neurodegenerative and Vascular Brain Disorders [1].

Blood Protein Linked to Alzheimers Brain Abnormalities

Neuroimaging is one of the most promising research areas for detection of the earliest stages of Alzheimer’s disease. Using neuroimaging together with proteomics, researchers report in the Journal of Alzheimer’s Disease that a blood test may reflect the levels of beta amyloid protein in the brain — a hallmark of the disease [1]. The findings may eventually lead to a blood test that helps to predict the risk for developing Alzheimer’s disease.
