Obsessive-compulsive disorder (OCD) is a lifelong mental illness and recovery from it is gradual and ongoing treatment is necessary to help prevent relapses.

The article presents commonly used pharmacological treatments and psychotherapy, as well as surgical and other forms of treatment, based on the variety of responses to the pharmacological treatment of obsessive-compulsive disorders (OCD).

If you have obsessive-compulsive disorder (OCD), your obsessive and compulsive behaviors are extreme enough to interfere with your everyday life. This is not the same as the "compulsive" behavior many people normally display, such as high standards of performance, perfectionism, and organization in work and recreational activities. Normal "compulsiveness" often serves a valuable purpose, contributing to a person's self-esteem and success on the job. OCD, on the other hand, involves obsessions and rituals that are very distressing and interfere with daily functioning.

The onset of OCD in a child is influenced by genetic and environmental factors, as well as obsessions about symmetry and exactness, and the majority of children with obsessive-compulsive symptoms also exhibit other concomitant disorders.

Doctor | Living With OCD | Resource Guide Screening for Obsessive-Compulsive Disorder (OCD) by Amy Scholten, MPH En Espanol (Spanish Version) The purpose of screening is early diagnosis and treatment. Screening tests are usually administered to people without current symptoms, but who may be at high risk for certain diseases or conditions.

Obsessive-Compulsive disorder is much more common than it was initially assumed and it was found that 1-year prevalence is in the range of 0.8-2.2 % in a study.

Obsessive-compulsive disorder (OCD) is one of the anxiety disorders that may develop early in life. It may affect children, especially boys who also have a diagnosis of attention deficit hyperactivity disorder (ADHD). It is also often diagnosed through adolescence and into early adulthood. Among adults, it affects women and men equally. It occurs in 0.5-1% of people in a given year. OCD is characterized by two features: obsessions and compulsions. Obsessions in OCDs are persistent thoughts, images, or impulses that seem intrusive or inappropriate by others. These ideas are often associated wit...

The objective of the study was the systematic review of the literature on Obsessive and Compulsive Disorder (OCD) measures.

These papers were those that, as well as including OCD measures, were considered as relevant according to criteria previously established from the analysis of 1066

Obsessive-Compulsive disorder (OCD) is a common psychiatric condition that leads to significant impairment in everyday life. Advancements in neurobiological investigations contributed to a better understanding of pathophysiological mechanisms behind OCD, leading to the understanding that current models employed to conceptualize OCD are not adequate and might be a significant factor in precluding further advancements in how OCD is treated. In this paper, we will use OCD as a model to discuss the limitations of the current diagnostic systems in Psychiatry and to present the novel perspectives ba...

O Transtorno de Ansiedade Obsessivo-Compulsivo (TOC) e o Transtorno da Personalidade Obsessivo-Compulsiva (TPOC) mostram congruências conceituais que historicamente têm confundido o diagnóstico de muitos pesquisadores e clínicos. Em parte, as ambigüidades provavelmente ocorrem devido aos equívocos muitas vezes apresentados pelos instrumentos diagnósticos e também pelo despreparo profissional. A outra fração de erros certamente acontece devido à grande semelhança entre os fenômenos comportamentais. Pela pertinência clínica que o questionamento traz, faz-se mister um aprofundamento teórico. O ob...

The aims of the present study were to examine the frequency of personality disorders in 36 patients with obsessive‐compulsive disorder (OCD), and to investigate whether patients with a coexisting personality disorder could be characterized by certain personality traits assessed by means of the Karolinska Scales of Personality (KSP). In total, 27 (75%) of the OCD patients fulfilled the DSM‐III‐R criteria for a personality disorder, and 13 patients (36%) had an obsessive‐compulsive personality disorder. Subjects with a comorbid personality disorder had significantly higher scores on most of the ...

It is concluded that, for compensation, patients would need to generate excessive amounts of attentional resources not available to overcome motor rigidity on the one side and visual distraction on the other side.

The study of intrusive mental imagery in anxiety is a growing area of interest. Whilst there is an appreciation of the variation in thematic content (Hirsch & Holmes, 2007), less is understood about the wider phenomenology and function of intrusive imagery across the anxiety disorders. The aim of the review is to adopt a transdiagnostic perspective, and compare and contrast the literature on intrusive imagery in anxiety in terms of the content, prevalence, frequency and characteristics. In addition, a further aim is to present preliminary findings concerning the function of imagery across the ...

The purpose of this report is to develop a psychological character analysis based on a movie character in “As Good as It Gets”. The movie depicts an individual (Melvin Udall) who suffers from a psychological disorder. However, as the movie progresses, the symptoms and the dysfunctions gradually becomes manageable by the subject himself displaying a recovery state of the character. This report will focus on the first half of the movie when the symptoms were intensified. Using a Multi Axial Diagnosis based on the DSM IV, this report further analyses the diagnostic criteria, possible causation, a...

Reviewing literature data on OCD onset finds that results from studies performed on OCD samples do not point toward a higher number or a higher severity of life events prior to OCD onset as compared to non-psychiatric samples drawn from the general population.

Contrary to some earlier studies, these data suggest that OCD does not generally influence reported sleep patterns unless there is a co-morbid diagnosis, however, a few non-depressed OCD patients did report sleep phase shifting, suggesting that a small proportion may have abnormal sleep parameters.

Abstract Prior to CBT treatment, nineteen obsessive–compulsive washers were administered Jones and Menzies's (1998a) obsessive–compulsive disorder (OCD) Origins Questionnaire (OOQ) in an attempt to examine the relevance of associative learning pathways in the aetiology of the disorder. The open-ended nature of the questions allows for the distinction between classical conditioning events and traumatic events in which no identifiable unconditioned stimulus can be found. On the basis of subjects' responses on the OOQ, associative learning was shown to account for only five cases of OC washing. O...

Handwashing protocol does not aggravate the washing compulsion of patients and the fear of infection with COVID-19 does not increase their fear of contamination.

To assess rates of psychotropic medication use in patients with obsessive–compulsive disorder (OCD) in seven different countries on five continents and to compare these with international treatment guidelines, a database of over-the-counter drugs used in these countries is analyzed.

Notes that although the obsessive compuslive disorder (OCD) is rich in religious qualities, it has tended to be neglected by pastoral counselors as well as by the secular mental health community. Observes that current OCD studies throw light on some historic figures, including leaders in various religious traditions. Challenges the pastoral arts and sciences to rethink some basic theological and biblical understandings OCD from its perspective of neurological and biological inheritance, thus providing pastoral services fresh new opportunities and openings

The aim of this paper is to summarize and discuss the existing online intervention for Obsessive-Compulsive Disorder (OCD). This paper is using the narrative approach and the search engine used include PubMed, SAGE Journals, EBSCO host and Cochrane Library.

abstract Obsessive-compulsive disorder (OCD) is a severe mental health problem of a heterogeneous nature. To add to discussions around defining coherent subtypes of OCD, this paper uses qualitative, cognitive linguistic analysis to show how episodes of OCD can be differentiated based on their underlying conceptualizations of threat. Spoken narratives of OCD episodes told by people with OCD were analyzed using image schema theory and cognitive approaches to deixis in discourse. Through an exploration of the participants’ subjective experiences of time, space, and uncertainty in their recounted ...

Obsessive-compulsive disorder is characterized by elevated anxiety caused by uncontrollable and intrusive thoughts called obsessions, and repetitive, ritualistic behaviors called compulsions. Children and adolescents with obsessive-compulsive disorder (OCD) cannot stop their worrying and anxiety. Obsession themes may include contamination, harming oneself or others, aggression, sexual misconduct, religiosity, forbidden thoughts, symmetry urges, and the need to tell, ask, or confess. Compulsions take the form of overt behavioral acts, rituals or covert mental acts (e.g. silently counting) [15]....

The diagnosis of OCD is purely clinical and no investigations are needed and a thorough history of the patient's obsessions and compulsions and their comparison with certain 'identifiable themes' will aid in the diagnosis.

I present the first complete theory of OCD. OCD occurs when excessive CRH is released in the prefrontal cortex, activating cAMP. cAMP is a major inducer of HCN channels, which promote repeated neural firing. The combination of CRH, which is strongly associated with stress, and repeated firing that cannot be controlled, explains all of the features of OCD, including obsessions and compulsions of all kinds.

Whether eating disorders can be conceptualized as a variant of obsessive-compulsive disorders raises the possibility that treatments proven effective for OCD could be successfully adapted for ED.

The sense of self-efficacy is a central entity of the subjective experience and seems particularly relevant in an occupational-based approach, knowing that it contributes to the dynamism of a system involving the person's aspects, the occupation, the adaptation, and the environment.

Findings reveal the efficacy and obstacles of treatments such as cognitive-behavioral therapy, selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), and evidence-based neurosurgical methods, offering a broad perspective on OCD management.

Recognition of this symptom as an ordinary obsession (unwanted, intrusive, repetitive, and associated with an anxiety-reducing compulsion or avoidance) facilitates treatment with cognitive-behavioral therapy for obsessive-compulsive disorder.
