Brain target for stress disorder
Blocking a molecule in the brain may "cure" post-traumatic stress disorder, according to US researchers. They showed that inhibiting a specific enzyme removed fear in mice and report to journal Nature Neuroscience that the finding may lead to new treatments. Around a third of people may suffer PTSD after an exceptionally traumatic event, such as a terrorist attack or a natural disaster. Experts said it was early days but the findings were worth exploring further.
