Levels of iron in the brain could be a warning sign of future Alzheimer’s disease, a new study suggests.High levels of the chemical element have been shown to increase brain toxins and trigger neurodegeneration, resulting in cognitive decline — especially when they interact with the abnormal amyloid and tau proteins that are the hallmark pathologies of Alzheimer’s disease.Researchers at Johns Hopkins University found that a special MRI technique called quantitative susceptibility mapping (QSM) can measure levels of brain iron.EARLY ALZHEIMER’S SIGNS DETECTED IN 3 MINUTES WITH NEW BRAINWAVE TEST"QSM is an advanced MRI technique developed over the last decade to measure tissue magnetic susceptibility with good precision," said the study’s senior author Xu Li, PhD, associate professor of radiology at Johns Hopkins University in Baltimore, Maryland, in a press release. "QSM can detect small differences in iron levels across different brain regions, providing a reliable and non-invasive way to map and quantify… ...[TheTopNews] Read More.
