Brain Molecule Identified as Key in Anxiety Model

August 15, 2019
Boosting a single molecule in the brain can change “dispositional anxiety,” the tendency to perceive many situations as threatening, in nonhuman primates, researchers from UC Davis, and the University of Wisconsin-Madison have found. The molecule, neurotrophin-3, stimulates neurons to grow and make new connections. The finding provides hope for new strategies focused on intervening early in life to treat people at risk for anxiety disorders, depression and related substance abuse. Current treatments work for only a subset of people and often only partially relieve symptoms.
