Final answer:

The caudate nucleus is the brain region noted to have anomalies in patients with obsessive-compulsive disorder (OCD).

Step-by-step explanation:

Patients with obsessive-compulsive disorder (OCD) are noted to have anomalies in the caudate nucleus. The caudate nucleus, a component of the basal ganglia, has been implicated in the pathophysiology of OCD. The striatum, which includes the caudate nucleus, plays a role in a wide array of cognitive processes including reward perception, motor planning, decision-making, motivation, reinforcement, and inhibition of action. Studies, such as brain imaging research, suggest hyperactivity in the frontal cortex and basal ganglia, including the caudate nucleus, in individuals with OCD.
