QEEG from 22 unmedicated people with obsessive-compulsive disorder, without depression, was compared with 20 matched controls. Patients had more slow-wave and less alpha activity, mainly over the left frontal and temporal areas, especially women and people who responded to treatment. More severe OCD went with more right parietal delta.
