There are many different theories about the cause of obsessive compulsive disorder. Some research has discovered a type of size abnormality in different brain structures. The majority of researchers believe that there is some type of abnormality in the neurotransmitter serotonin, among other possible psychological or biological abnormalities; however, it is possible that this activity is the brain's response to OCD, and not its cause. Recent research has revealed a possible genetic mutation that could be the cause of OCD. Resea ...

Modern research has revealed that OCD is much more common than previously thought. An estimated two to three percent of the population of the United States is thought to have OCD or display OCD-like symptoms. Because of the condition's personal nature, and the lingering stigma that surrounds it, there may be many unaccounted-for OCD sufferers, and the above percentages could be even higher. The typical OCD sufferer performs tasks (or compulsions) to seek relief from obsessions. To others, these tasks may appear simple and unnecessary. ...

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 corr ...

OCD can be treated with behavioral therapy (BT) or Cognitive therapy (CBT) and with a variety of medications. 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. Medications can help make the treatment go faster and easier, but most experts regard BT/CBT as clearly the best choice. Medications generally do not produce as much symptom control as BT/CBT, and sy ...
