With OCD, the brain circuits driving concerns, fears and anxieties get stuck, like a car in a certain gear or a record skipping incessantly, Lipsman said. The structures are in overdrive.

Toronto neurosurgeon Nir Lipsman said the last thing he wants to do is reduce a disease as complex as OCD or major depressive disorder down to a single target or single circuit in the brain.
