Scientists have located an area in the brain that fails to "kick-in" for people with obsessive compulsive disorder and those at risk of developing the condition.
The discovery could allow researchers to diagnose the debilitating disorder much earlier and better track how drug treatments are working, they reported in the journal Science.
"The main finding is that in people with obsessive compulsive disorder and their unaffected relatives, part of their orbitofrontal cortex didn't kick in on line as it should have," said Samuel Chamberlain, a neuroscientist at the University of Cambridge, who led the study.
"This is the first study to identify underactive brains in people at risk of OCD."
OCD is a psychiatric anxiety disorder that tends to run in families and is marked by recurrent and persistent thoughts and impulses, such as uncontrollable and repeated hand washing. It affects about 2 to 3 percent of people worldwide at some point in life.
