| Treatment OCD can be treated with Behavioral therapy (BT), Cognitive therapy (CT), medications, or any combination of the three. Psychotherapy can also help in some cases, while not one of the leading treatments. According to the Expert Consensus Guidelines for the Treatment of Obsessive-Compulsive Disorder (Journal of Clinical Psychiatry, 1995, Vol. 54, supplement 4), the treatment of choice for most OCD is behavior therapy or cognitive behavior therapy. The specific technique used in BT/CBT is called Exposure and Ritual Prevention (also known as Exposure and Response Prevention) or ERP; this involves gradually learning to tolerate the anxiety associated with not performing the ritual behavior. At first, for example, someone might touch something only very mildly "contaminated" (such as a tissue that has been touched by another tissue that has been touched by the end of a toothpick that has touched a book that came from a "contaminated" location, such as a school.) That is the "exposure." The "ritual prevention" is not washing. Another example might be leaving the house and checking the lock only once (exposure) without going back and checking again (ritual prevention). The person fairly quickly habituates to the (formerly) anxiety-producing situation and discovers that their anxiety level has dropped considerably; they can then progress to touching something more "contaminated" or not checking the lock at all — again, without performing the ritual behavior of washing or checking. Pharmacologic treatments include selective serotonin reuptake inhibitors (SSRIs) such as paroxetine (Paxil, Aropax), sertraline (Zoloft), fluoxetine (Prozac), and fluvoxamine (Luvox) as well as the tricyclic antidepressants, in particular clomipramine (Anafranil). SSRIs prevent excess serotonin from being pumped back into the original neuron that released it. Instead, the serotonin can then bind to the receptor sites of nearby neurons and send chemical messages or signals that can help regulate the excessive anxiety and obsessive-compulsive thoughts. SSRIs seem to be the most effective drug treatments for OCD, and help about 60% of OCD patients, but do not "cure" OCD (Barlow & Durand, 2006). Other medications like gabapentin (Neurontin), lamotrigine (Lamictal), and the newer atypical antipsychotics olanzapine (Zyprexa) and risperidone (Risperdal) have also been found to be useful as adjuncts in the treatment of OCD. The naturally occurring sugar Inositol may be an effective treatment for OCD. Recent research has found increasing evidence that opioids may significantly reduce OCD symptoms, though the addictive property of these drugs likely stands as an obstacle to their sanctioned approval for OCD treatment. Anecdotal reports suggest that some OCD sufferers have successfully self-medicated with opioids such as Ultram and Vicodin, though the off-label use of such painkillers is not encouraged, again because of their addictive qualities. Studies have also been done that show nutrition deficiencies may also be a probable cause for OCD and other mental disorders. Certain vitamin and mineral supplements may aid in such disorders and provide the nutrients necessary for proper mental functioning. For some, neither medication, support groups nor psychological treatments are helpful in alleviating obsessive-compulsive symptoms. These patients may choose to undergo psychosurgery as a last resort. In this procedure, a surgical lesion is made in an area of the brain (the cingulate bundle). In one study, 30% of participants benefited significantly from this procedure (Barlow & Durand, 2006). Neuropsychiatry OCD primarily involves the brain regions of the striatum and the cingulate cortex, especially the striatum. OCD involves several different receptors, mostly H2, M4, nk1, NMDA, and non-NMDA glutamate receptors. The receptors 5-HT1D, 5-HT2C, and the mu opioid receptor exert a secondary effect. The H2, M4, nk1, and non-NMDA glutamate receptors are active in the striatum, whereas the NMDA receptors are active in the cingulate cortex. The activity of certain receptors is positively correlated to the severity of OCD, whereas the activity of certain other receptors is negatively correlated to the severity of OCD. Those correlations are as follows: Activity positively correlated to severity: * H2 * M4 * nk1 * non-NMDA glutamate receptors Activity negatively correlated to severity: * NMDA * mu opioid * 5-HT1D * 5-HT2C The central dysfunction of OCD involves the receptors nk1, non-NMDA glutamate receptors, and NMDA, whereas the other receptors exert secondary modulatory effects. Pharmaceuticals that act directly on those core mechanisms are aprepitant (nk1 antagonist), riluzole (glutamate release inhibitor), and tautomycin (NMDA receptor sensitizer). The drugs that are popularly used to fight OCD lack efficacy because they do not act upon the core mechanisms. |
