Authors: Mannino G Abstract While psychopathological phenomena of obsessive-compulsive disorder (OCD) have been well described some time ago, instead there is still need for a deeper understanding of mechanisms underlying psychopathological phenomena themselves. About this, a recently proposed concept - the 'Retrospective Identification of Motivations and Inclinations' (RIMI) - seems to have a promising explanatory capacity about different aspects of obsessive-compulsive disorder. For example, as shown elsewhere, it appears to shed new light on the so-called 'fear of self' in OCD. In this paper, the role of RIMI in...

CONCLUSIONS: Our results, although preliminary, seem to suggest that a longer duration of untreated illness in OCD is associated with poorer outcome in terms of response to SRI treatments. It is imperative to do all the possible to shorten the DUI, both by improving access to mental health services, improving the ability of primary care physicians and mental health professionals to recognize OCD, and disseminate best-practice prescription guidelines.

Authors: Sharma LP, Reddy YCJ Abstract Obsessive Compulsive Disorder (OCD) and Obsessive Compulsive Symptoms (OCS) are known to be highly comorbid with bipolar disorder and schizophrenia. Comorbid OCD/OCS influences the course of schizophrenia and bipolar disorder. There is also some evidence to suggest that a diagnosis of OCD may be associated with elevated risk for later development of psychosis and bipolar disorder. Comorbid OCD/OCS is associated with a greater severity of schizophrenia phenotype and poorer prognosis. In addition, certain atypical antipsychotics, clozapine in particular are known to induce or wo...

Authors: Westwell-Roper C, Stewart SE Abstract Obsessive-compulsive disorder (OCD) affects 1%-3% of children worldwide and has a profound impact on quality of life for patients and families. Although our understanding of the underlying etiology remains limited, data from neuroimaging and genetic studies as well as the efficacy of serotonergic medications suggest the disorder is associated with the fundamental alterations in the function of cortico-striato-thalamocortical circuits. Significant delays to diagnosis are common, ultimately leading to more severe functional impairment with long-term developmental consequ...

Authors: Thamby A, Khanna S Abstract Personality disorders are a common comorbidity in obsessive-compulsive disorder (OCD). The effect of comorbidity on the symptom presentation, course, and treatment outcome of OCD is being discussed here. OCD and obsessive-compulsive personality disorder (OCPD) though similar in their symptom presentation, are distinct constructs. Schizotypal disorder, OCPD, and two or more comorbid personality disorders have been found to be consistently associated with a poor course of illness and treatment response. Further research is needed to determine treatment strategies to handle the per...

Authors: Manjula M, Sudhir PM Abstract New-wave behavioral therapies in obsessive-compulsive disorders (OCDs) comprise of third-wave therapies and newer cognitive therapies (CTs). This review covers outcome studies published in English until December 2017. A total of forty articles on mindfulness-based CT, metacognitive therapy, acceptance and commitment therapy, and danger ideation reduction therapy in the form of single-case studies, case series, open-label trials, two-group comparison studies, and randomized controlled studies were included. Results show that studies on these therapies are limited in number. Met...

Authors: Shimshoni Y, Shrinivasa B, Cherian AV, Lebowitz ER Abstract Family accommodation describes changes that family members make to their own behavior, to help their relative who is dealing with psychopathology, and to avoid or alleviate distress related to the disorder. Research on family accommodation has expanded greatly in the past few years. The aim of this study was to provide a synthesized review of recent findings on family accommodation in psychopathology. Electronic databases were searched for available, peer-reviewed, English language papers, published between September 2015 and March 2018, cross-ref...

Authors: Hezel DM, Simpson HB Abstract Obsessive-compulsive disorder (OCD) is characterized by distressing thoughts and repetitive behaviors that are interfering, time-consuming, and difficult to control. Although OCD was once thought to be untreatable, the last few decades have seen great success in reducing symptoms with exposure and response prevention (ERP), which is now considered to be the first-line psychotherapy for the disorder. Despite these significant therapeutic advances, there remain a number of challenges in treating OCD. In this review, we will describe the theoretical underpinnings and elements of ...
