AbstractObsessive-compulsive disorder (OCD) is a chronic psychiatric illness and 1 of the most common anxiety disorders with the prevalence of 3%. Although its pathogenesis remains unclear, the traditional model focused on alternations in the serotonin system. Selective serotonin reuptake inhibitors provide the most effective treatment; however, as much as 40–60% of patients do not respond to antidepressants therapy. Thus, attention has shifted towards other neurotransmitter systems and related neuroanatomical structures. Recently, there is extensive evidence showing a key role of glutamate pathways abnormalities within the cortico-striatal-thalamo-cortical circuitry and temporal lobes in OCD pathogenesis. In this review, we link together the existent neuroanatomical, neurophysiological, and neuropsychological evidence to argue for potential benefits of adjuvant treatment with glutamatergic agents, especially memantine. By a targeted de-excitation effect on the glutamatergic system in the temporal lobes and connected brain regions, memantine might further alleviate OCD symptoms. This effect should be even more pronounced in certain subtypes of patients with specific cognitive deficits and maladaptive compensatory memory processes (e.g., checkers).

Primary Relationship

AbstractRecently, in a review article in this journal, Vlček and colleagues described the putative role played by the glutamatergic system in obsessive-compulsive disorder (OCD) and how this might explain the effects of certain treatments. They describe a neuroanatomical model, which includes a specific role of the amygdala-hippocampus complex (AHC) and would complete the classic cortico-striatal-thalamo-cortical (CSTC) mechanism of OCD. The role of the AHC can perhaps be better understood when considering its ancient relationship to the rest of the forebrain of mammals. This leads to distinguishing between primary (lamprey-like), secondary (amphibian-like) and tertiary (mammal-like) parts of the forebrain including amygdaloid, ventral extrapyramidal and dorsal extrapyramidal systems, respectively. A specific role in OCD may be played by the habenula-projecting part of the pallidum, which evaluated the result of behaviour in human’s earliest vertebrate ancestors. The addition of these primary relationship to the authors’ description could be fruitful when planning the future research, as suggested by them.

The Impact

Pupil with Obsessive-Compulsive Disorder. Over the past twenty years childhood OCD has received more attention than any other anxiety disorder that occurs in the childhood. The increasing interest and research in this area have led to increasing number of diagnoses of OCD in children and adolescents, which affects both specialists and teachers. Depending on the severity of symptoms OCD has a detrimental effect upon child's school performance, which can lead almost to the impossibility to concentrate on school and associated duties. This article is devoted to the obsessive-compulsive disorder and its specifics in children, focusing on the impact of this disorder on behaviour, experience and performance of the child in the school environment. It mentions how important is the role of the teacher in whose class the pupil with this diagnosis is and it points out that it is necessary to increase teachers' competence to identify children with OCD symptoms, to take the disease into the account, to adapt the course of teaching and to introduce such measures that could help children reduce the anxiety and maintain (or increase) the school performance within and in accordance with the school regulations and curriculum.

The Fourth International Obsessive Compulsive Disorder Conference (IOCDC) was held February 10–12, 2000, on the beautiful island of St. Thomas. The IOCDC is an annual meeting which brings together the world's leading experts in obsessive-compulsive disorder (OCD) and related disorders in a small workshop setting to present recent research advances, discuss gaps in our current knowledge, and plan or international approaches that address these knowledge gaps. The IOCDC meetings have been held on islands on both sides of the Atlantic—Capri, Guadeloupe, Madeira, and now St. Thomas.The International Organizing Committee consists of Eric Hollander, MD (USA), Joseph Zohar, MD (Israel), and Donatella Marazziti, MD (Italy). The proceedings are generously supported by an unrestricted educational grant from Solvay Pharmaceuticals Inc. and Solvay Pharmaceuticals, and we would like to acknowledge the very important contributions of Chantal Vekens and Mary Blangiardo of Solvay. Also, an mportant part of the success of these meetings stems from the very active role of the chairpersons and cochairpersons of the workshops who lead the discussions, who synthesize the future directions and prepare the manuscripts that result from these discussions that appear in this academic supplement.The meeting led off with a state-of-the-art plenary address by Mark George, MD (USA), describing how new methods of brain stimulation are improving research and therapy in OCD and promise to revolutionize neuropsychiatric research and herapy over the next decade. He describes how transcranial magnetic stimulation (TMS) is used to test the circuits in OCD and test electrophysiologic evaluations of cortical inhibition n OCD. Newer techniques that are less invasive than ablative surgery and appear promising in OCD therapy include vagus nerve stimulation and deep brain stimulation.

Objective: Nowadays, the outbreak of Coronavirus (COVID-19) is one of the most stressful resources that has led to the rise of different levels of psychological crisis. In addition to the countries affected by the COVID-19, such as China, European and American countries, Iran has appeared as one of the most affected countries with high infected cases and deaths. Thus, the purpose of this study was to investigate the role of self-talk in predicting death anxiety, obsessive-compulsive disorder, and coping strategies in the face of COVID-19. Method: This descriptive and correlational study was conducted on 354 adults living in Ardabil, Iran, who were selected using cluster sampling from 21 January to 19 March 2020. Self-Talk questionnaires, Coping Strategies, Death Anxiety, and Obsessive-Compulsive questionnaires were used for data collection. Descriptive statistics, Pearson correlation, and multiple linear regression were used for data analysis. Results: The findings revealed a significant positive relationship between self-talk and problem-centered coping style. Also, significant negative relationships were found between self-talk and emotional coping style, death anxiety, and obsessive-compulsive disorder. Furthermore, based on the results of the regression test, self-talk predicted problem-centered style, emotional-coping style, death anxiety, and obsessive-compulsive disorder. Conclusion: The results of this study emphasize the need for psychological crisis intervention during the COVID-19 outbreak. Also, this study provides an important step in shifting attention to self-talk skills from sport psychology fields toward clinical psychology, especially about the mental impacts of COVID-19.
