The areas of the brain affected in obsessive compulsive disorder

Patients with obsessive compulsive disorder (OCD) exhibit increased metabolic activity in the cortico-basal ganglia network compared with healthy controls. Hyperactive neurotransmitter circuits between the cortex, basal ganglia and thalamus have been implicated in the disorder. Hypofunction of serotonergic neurones arising from the rostral raphe nucleus may result in a lack of inhibitory effect on the putative OCD pathway. Furthermore, overactivity of dopaminergic neurones arising from the substantia nigra may produce excessive excitation in the brain areas implicated in OCD.

These are considered the newest classifications and brain pathways for OCD

•The DSM-IV-TR has multiple classes of addictive substances.

•The DSM-V will list addictions under the broad category of obsessive-compulsive related disorders.

•Obsessive-compulsive related disorders will include those disorders that share obsessions or compulsions. (Increased caudate activity.)

•The second category includes behavioral and substance addictions. These disorders are characterized by impulsive choice and reward sensitivity. (fronto-striatal brain dyfunction.)

•(Hollander, 2006)
