New non-invasive method can detect Alzheimer's disease early

(Northwestern University) Northwestern University researchers have developed a noninvasive MRI approach that can detect the Alzheimer's disease in a living animal, well before typical Alzheimer's symptoms appear. The research team developed an MRI probe that pairs a magnetic nanostructure with an antibody that seeks out the amyloid beta brain toxins responsible for onset of the disease. The accumulated toxins, because of the associated magnetic nanostructures, show up as dark areas in MRI scans ...
