Anxiety - it's in the blood



Panic attacks, posttraumatic stress, and other anxiety disorders hit more than 19 million Americans. Getting diagnosed is often an arduous, uncertain process--but a new blood test can detect these disorders in hours, say scientists at the Hebrew University of Jerusalem. After reviewing the psychiatric history of 461 volunteers, researchers found that by checking for high levels of acetylcholinesterase (AChE), a blood protein people release when under stress, they could identify anxiety disorders 90% of the time. It's likely the test will be available within a year, leading to faster treatment for many.
