Is OCD too much or too little dopamine?

In OCD, people develop obsessions (intrusive thoughts or images that trigger significant emotional distress) and compulsions (behaviors someone engages in to decrease the upsetting obsessions).

Does increased dopamine cause OCD?

The neurobiological understanding of obsessive–compulsive disorder (OCD) includes dysregulated frontostriatal circuitry and altered monoamine transmission. Repetitive stereotyped behavior (e.g., grooming), a featured symptom in OCD, has been proposed to be associated with perturbed dopamine (DA) signaling.
