A small study, conducted by the researchers from Washington University School of Medicine, suggests that a new MRI brain scan can be more efficient in determining the patient’s risk of developing Alzheimer’s disease than common clinical tests, long before the disease setup.
The study involved 61 participants who were examined with the help of the new method. The new MRI technique has been conducted using diffusion tensor imaging (DTI) to assess the state of the brain white matter. The technique was found to be 89–95% accurate.
Study leading author Dr. Cyrus Raji, an assistant professor of radiology at the school’s Mallinckrodt Institute of Radiology, explains: “With DTI you look at the movement of water molecules along white matter tracts, the telephone cables of the brain. When these tracts are not well connected, cognitive problems can result.”
