Detailed explanation-1: -Functional imaging studies have reported with remarkable consistency hyperactivity in the orbitofrontal cortex (OFC), anterior cingulate cortex (ACC), and caudate nucleus of patients with Obsessive-Compulsive Disorder (OCD).
Detailed explanation-2: -A group of children who were diagnosed with both conditions were treated only for OCD. As their OCD symptoms went down, so did the inattention, hyperactivity, and impulsivity. Researchers concluded that OCD may have created ADHD-like symptoms.
Detailed explanation-3: -Recent evidence suggests that the ubiquitous excitatory neurotransmitter glutamate is dysregulated in OCD, and that this dysregulation may contribute to the pathophysiology of the disorder.
Detailed explanation-4: -Glutamate is the major excitatory neurotransmitter, which contributes to brain development and plays a central role in circuits consistently implicated in OCD, including direct driving influences on serotonergic dorsal raphe neurons related to anxiety and tic behaviours [84–86].
