  • OCD is thought to spring from a malfunction in neurological circuitry that can be seen on MRI images: when a person with OCD engages in obsessive thoughts, certain areas of the brain light up more than they would in a normal person, a sign of heightened activity. The disorder may be an exaggeration of normal behaviors that enhance survival, behaviors that evolution hard-wired into the human brain -- watching for predators, checking to make sure the fire is out, protecting children, avoiding disease.
