When the researchers compared the Tourette's patients who had OCD with those who did not, they found that the patients who had both disorders exhibited greater activity in the primary motor cortex and precuneus, an area that plays a role in self - awareness.

Previous research has suggested that in patients who suffer from both disorders, OCD might show up more in the form of compulsions than obsessions, and these findings support that idea: the increased activity of the precuneus may reflect individuals» efforts and ability to resist obsessive thought, and the motor cortex may be more active because OCD is manifesting itself more physically than mentally.
