Answer:
Dopamine
Obsessive-compulsive disorder (OCD) is linked to defects in the cortico-striatal-thalamic-cortical (CSTC)
circuitry, which may be linked to neurotransmitter dysregulation throughout this network. Serotonin,
dopamine, glutamate, and -aminobutyric acid (GABA) are the main neurotransmitters throughout the
CSTC.
Compulsive behaviors linked to OCD are likely the product of a related dopaminergic reward
system dysfunction. Continuous ventral striatum activation may lead to an undirected expectation of
reward. Anxiety and a desire to fill the gap are caused by unfulfilled expectations.
