A new brain-imaging meta-analysis has uncovered the first consistent biochemical signature across multiple anxiety disorders (a shift in a single molecule that moves in the opposite direction of every major psychiatric condition studied to date). Even more surprising, a separate study in young adults under metabolic strain reveals a nearly identical pattern emerging outside the brain. In this episode, we trace the science behind this unexpected overlap, follow the trail of this overworked molecule, and explore what these clues suggest about the hidden biology anxiety leaves behind.
