¶ … psychological basis of mental illness is certainly only half of the story. Though mental illness is genetic, the actual symptoms and condition being presented is based on a careful marriage between biological and environmental factors. In particular, obsessive-compulsive disorder (OCD), is a mental illness in which "people have unwanted and repeated thoughts, feelings, ideas, sensations or obsession, or behaviors that make them feel driven to do something (compulsions)" (National Institute of Mental Health, 2011). This mental illness, like many others is multi-faceted, in that there is a physiological process associated with it, a set of symptoms that manifest, certain diagnostic criterion and then a set of treatment options. Foremost, the physiological process of mental illness is mainly concerned with the brain and certain regions of it. The physiological process is a process that evaluates the neural mechanisms of perception and behavior. Research examining the brain has found that "a selective deficit in neurobehavioral response suppression in may be related to failures in the development maturation of frontostriatal circuitry" (Rosenberg, 1998, p. 623). Upon further exploration of the physiological the researcher's conclusion, it is safe to conclude that certain neurons have not matured which has contributed to the physiological process of having OCD. Since the neurons are not communicating with each other by all means possible, certain messages and communications are lost, thus leading the obsession and compulsions...

Symptoms include but are certainly not limited to having "persistent, upsetting thoughts (obsessions) and use rituals (compulsions) to control the anxiety these thoughts produce" (National Institute of Mental Health, 2011). People with OCD have these obsessions and compulsions to such an intense degree that it "interferes with daily life and they find the repetition distressing" (National Institute of Mental Health, 2011)
In order to diagnose OCD in a patient, one must gather information about the over behavioral rituals that are being preformed as well as the cognitive rituals that may also be preformed (Swinson, Richard P., 2001). It is important to gain as much of a detailed composite of the individual suffering from the obsessions and compulsions to truly evaluate what is going on. Additionally, "patients may not be aware that they are engaging in repetitive cognitive activity that serves to reduce anxiety," so in turn, it is important to ask directly "if patients report certain fears but do not report associated behavioral rituals" (Swinson, Richard P., 2001). Finding out as much information about the person's daily life is imperative to diagnosing OCD. Observing a person with OCD may yield observations including seeing the person wash their hands over and over again if they have a…
