Biochemical changes in the brains of healthy individuals can be identified by an imaging technique - proton MR spectroscopy - indicating whether they may be at risk for Alzheimer's disease, researchers from the Mayo Clinic reported in the journal Neurology.
Kejal Kantarci, MD, MSc, and team carried out a study involving 311 participants aged over 70 years from the May Clinic Study of Aging. None of them had cognitive problems. Proton MR spectroscopy, an advanced brain imaging technique, was used to determine whether any of them had abnormalities in various brain metabolites that might be Alzheimer's disease biomarkers.
PET scans were used to assess amyloid-beta deposits (plaques) in the brain. Plaques are one of the initial signs of Alzheimer's disease onset. The volunteers also underwent various tests which assessed their language, memory and other skills. Continue to read: medilexicon.com
