How does OCD affect the brain?

Brain structure and function

Studies show that OCD patients have excess activity in frontal regions of the brain, including the orbitofrontal cortex (OFC

orbitofrontal cortex (OFC

The orbitofrontal cortex (OFC) is a prefrontal cortex region in the frontal lobes of the brain which is involved in the cognitive process of decision-making. In non-human primates it consists of the association cortex areas Brodmann area 11, 12 and 13; in humans it consists of Brodmann area 10, 11 and 47.

) and anterior cingulate cortex (ACC), which could explain their intrusive thoughts and high levels of anxiety, respectively.
