Anti-Stress Drug?
Reported November 19, 2008
(Ivanhoe Newswire) — Doctors are finding promising effects from a drug that could make stress disappear.
In a small test on rats that were put under stressful conditions, researchers found exposing them to a small dose of muscimol — a drug that temporarily inactivates the amygdala region of the brain — eliminated the effects of stress completely.
It was as if the experience had never happened to them, Lauren Jones, a University of Washington psychology doctoral student, was quoted as saying. Inactivation of the amygdala took the stress away.
Neuroscientists say stress can have long-lasting effects on cognition, including memory, learning and decision making processes. Stress can also contribute to anxiety, depression, schizophrenia and drug-use relapse in humans.
Doctors caution more tests will need to be done to understand how deactivation of the amygdala relates to stress.
