Quinpirole Sensitization Rat Model Essay

Obsessive-compulsive disorder involves a chemical imbalance in the brain. This chemical imbalance is thought to be the main reason for obsessions and compulsions, although there may be other factors as well.  Nearly one in every fifty people suffers from symptoms of OCD ("Escape"), and approximately 5 million Americans are affected by

The following is an overview about Obsessive-Compulsive Disorder (OCD), one of the most difficult psychiatric illness to be understood. The way of doing certain behaviors, thoughts or routines repeatedly is the essential condition of a person with OCD. In general, it is known and described by someone who is extremely perfectionist and meticulous. Unfortunately, they do realize those habits and be able to stop doing it. Common behaviors are such as checking locks, doors, stove bottoms, and lights, hand washing, counting things, or having recurrent intrusive thoughts of hurting oneself or somebody else.

OCD follows a pretty typical cycle, in which patients have obsessions that can become triggered, and when they become triggered, the patient feels anxiety. In order to combat that anxiety, they will try to relive it by creating behaviors, called compulsions. The compulsions temporarily provide relief until the obsessions are triggered again. There are a few common types of OCD:

This usually occurs when they are not obsessing. They know that their obsessions and compulsions are based on unwarranted fears. However, there are other times when they feel that their fears are completely valid. Even though people with OCD know that their fears are unwarranted, many try to rid themselves of these unwanted, obsessive thoughts and to stop performing their compulsive behaviors. Some can control themselves more while at work or at school. However, over the months or years, people's abilities to resist their feelings weaken and in the some cases, these rituals that the people with OCD perform can become so time-consuming which impedes their ability to have a full and normal life. Although OCD can consume one's life, people try to keep their disorder from their friends rather than to seek help. Most of the time people are successful in keeping it a secret from their friends and co-workers, but the downside is that they do not get the necessary help until years later after which they have learned to work their lives around their obsessions and compulsions.

Obsessive compulsive disorder, also know as ODC, is a complex mental illness that involves repeating thoughts know as obsessions and repeating actions know as compulsions (Parks 8). OCD affects males and females of all types (Parks 8). According to the National Institute of Mental Health, approximately one-third of OCD cases in adults begin in the childhood stages (Chong and Hovanec 11). Scientists believe that OCD is related to a faulty brain circuitry that could possibly be hereditary (Parks 9). Theories based on more recent studies show that OCD is a biological brain defect (Sebastian 32). It affects the frontal lobes of the brain (Ken and Jacob 1). Many OCD symptoms have been recorded since the 15th century (Sebastian 21). By the 19th century, science had developed more and explained that OCD was a mental and emotional disorder instead of supernatural forces (Sebastian 29). OCD is two times more common of a disease than schizophrenia and bipolar disorder (Ken and Jacob 1). There are three forms of OCD. The three forms are episodic, continuous, and deteriorative. Episodic OCD has recurring episodes of illness lasting for a limited time.

One of the more compelling theories of the cause of OCD is the serotonin theory. Two different theories based on serotonin are more prominent than the rest. Giddens (2009) explains the theory by stating that OCD is caused from a lack of a chemical substance called serotonin (a neurotransmitter). Her theory is supported by the use of drugs that increase the amount of serotonin in the brain which relieve many symptoms of OCD. On the other hand, Penzel (2000) describes the serotonin theory as a disrupted transmission of serotonin. When the serotonin is being returned to it’s vesicle chamber, the last step of neural-transmission takes place prematurely, which then causes a brain dysfunction and forms compulsions. Though both serotonin theories do not agree with each other, both theories argue on behalf of nature in the nature versus nurture debate since serotonin and the lack or faulty

Obsessive compulsive disorder (OCD) is a debilitating neuropsychiatric disorder with a lifetime prevalence of 2 to 3 percent and is estimated to be the 10th leading cause of disability in the world. Patients with OCD experience recurrent, intrusive thoughts (obsessions) and/or repetitive, stereotyped behaviors (compulsions) that last for at least one hour per day and significantly interfere with the individual 's normal level of functioning. The intrusive obsessional thoughts

Obsessive-compulsive disorder, also known as just simply OCD, affects from 1% to more than 5% of the total population. This paper gives an overview of current diagnosis criteria, statistical data, causes of the disorder as well as current treatment options. While in the past, most clinicians use drug therapy to treat OCD patients, today treatment options are focusing on a combination of psychological therapy combined with drug therapy in an effort to address underlying problems causing the manifestation of OCD while still treating the symptoms of the disorder.

Obsessive Compulsive Disorder (OCD) is a disorder that can affect children and adults. In order to fully understand OCD, many different areas of the disorder must be reviewed. First, OCD will be defined and the diagnosis criteria will be discussed. Secondly the prevalence of the disorder will be considered. The different symptoms, behaviors and means of treatment are also important aspects that will be discussed in order to develop a clearer understanding of the implications of obsessive compulsive disorder.

Method A, with a total of 40 inpatients (32 females (80 %); mean age=31.25 years) suffering from OCD were randomly assigned to a treatment (administration of additional memantine) or a control group (which was the placebo). The treatment had lasted for 12 consecutive weeks, and all patients were treated with selective serotonin inhibitors, or clomipramine. The patients had to complete the Yale–Brown Obsessive Compulsive Scale four times.

"OCD patients have a pattern of distressing and senseless thoughts or ideas- obsessions- that repeatedly well up in their minds. To quell the distressing thoughts, specific patterns of odd behaviors- compulsions- develop." (Gee & Telew, 1999)

You may have once thought you had OCD before because of an obsessions or habit that you pay attention to now and again. An example of this would be wanting to have a very neat or clean house and starting to think that it means you are a “neat freaks”. With this in mind, it would seem fit to diagnose everyone with obsessive-compulsive disorder otherwise known as OCD, yet that is not the case. The main difference with those who are diagnosed with OCD is that these obsessions and compulsions begin to greatly interfere with one’s daily lives while also causing a large amount of distress for the individual (CAMH, 2001).

Obsessive compulsive disorder is a common psychological disorder that is often associated with misconstrued stereotypes. OCD is considered an anxiety disorder consisting of obsessions that are often combined with compulsions. These obsessions are usually recurrent and persistent specific thoughts and be urges. Compulsions make up the second part of OCD. They are repetitive behaviors performed according to rigid rules that are completed in an attempt to help prevent obsessions from becoming true. The compulsions are maintained by negative reinforcement meaning that the patient continues to perform the compulsions because the obsessions are prevented. This idea forces the patient to continue the vicious cycle of performing compulsions to prevent

Obsessive-Compulsive Disorder, also known as OCD, is a disorder that affects about two to three percent of the population (UOCD). Knowing what OCD is and who it affects is just step one in understanding the psychology of this disorder. The psychological symptoms of OCD can be quite varied which can make it difficult to diagnose. Understanding the therapy techniques and how people with OCD live their daily lives is one of the most vital part in the psychology of OCD. While the roots of the disorder may be complex, understanding the disorder in everyday life is quite simple.

Obsessive compulsive disorder is a disease that many people know of, but few people know about. Many people associate repeated washing of hands, or flicking of switches, and even cleanliness with Obsessive Compulsive Disorder (OCD), however there are many more symptoms, and there are also explanations for those symptoms. In this paper, I will describe what obsessive compulsive disorder is, explain some of the effects of it, and explain why it happens. I will also attempt to prove that while medication doesn’t cure OCD, it vastly improves one’s quality of life. Furthermore I intend to show that behavior therapy (cognitive based therapy) is another useful tool in helping a person to overcome their OCD.
