Amyloid Beta and Serotonin May Be Keys to Predicting Who Develops Late-Life Depression

Posted by in categories: biotech/medical, neuroscience

Image from a Johns Hopkins Medicine study showing PET scans from brains of people with and without late-life depression. The brains of patients with late-life depression show more yellow to red regions (scans on the left), indicating higher amyloid beta protein levels, and more blue regions (scans on the right), indicating lower serotonin transporter levels. Both imaging measures are markers of late-life depression. Credit: Graphic adapted from Smith et al, Nature, Sept. 13, 2021.
