SynopsisThis paper presents evidence that on an information processing task, designed to investigate putative inhibitory mechanisms in selective attention, obsessive compulsive disordered individuals can be clearly distinguished from other anxiety disorder clients and show significantly higher scores on questionnaire measures designed to detect schizotypy in the normal population. It is suggested that these results provide some support for the idea that obsessive compulsive disorder may be misclassified as an anxiety disorder and may in fact be categorically more closely aligned to the schizophrenic constellation of disorders.

Objective:Fronto-striatal dysfunction has been discussed as underlying symptoms of Tourette syndrome (TS) with co-morbid Obsessive Compulsive Disorder (OCD). This suggests possible impairments of executive functions in this disorder, which were therefore targeted in the present study.Results:A comprehensive series of neuropsychological tests examining attention, memory and executive functions was performed in a group of 14 TS/OCD in co-occurrence with OCD patients and a matched control group.Results:While attentional and memory mechanisms were not altered, TS/OCS patients showed deficits in executive functions predominately in the areas of response inhibition and action monitoring.Conclusions:These findings provide further evidence for a substantial impairment of the frontal-striatal-thalamic-frontal circuit. We propose that the deficits in monitoring, error detection and response inhibition constitute the major impairment of TS/OCD patients in the cognitive domain.

AbstractBackgroundObsessive compulsive disorder (OCD) has a complex etiology related to multiple neuropsychological factors. OCD is associated with several candidate genes but results are discordant. The objective was to explore the association between five polymorphisms related to neurotransmitters, the risk of an OCD diagnosis and the performance in four executive functions tests done with Colombian patients diagnosed with this condition.Methods63 patients and 65 controls matched by gender and age were genetically analyzed. For the study of the relation between cognitive function and phenotypes, a subsample of 33 patients and 31 controls was used. The Stroop test, Wisconsin Card Sorting Test (WCST), Tower of London and Trail Making Test (TMT) for executive function assessment were applied and the SNPs analyzed were: COMT (rs4680), MAO-A (rs6323), HTTLPR (rs25531), HT2A (rs6315) and SLC1A1 (rs301434).ResultsDifferences in the conceptualization of the WCST test (p = 0.023) and Stroop interference score (p = 0.041) between cases and controls were obtained. After analyzing the relationship between genotypes and sub-scores of the tests, associations between the presence of MAO-A, SLAC1A1, HTTLPR and HT2A alleles and tests sub-scores were found.DiscussionThis characterization of children with OCD is a new field of work in Colombia and one of the first works performed in Latin America. The sample size and the number of polymorphisms analyzed in this population should be increased.

AbstractThis article presents an overview of sensorymotor aspects of obsessive-compulsive disorder (OCD). These phenomena have received less attention than obsessions and compulsions, but are nonetheless important in the development, maintenance, phenomenology, and treatment of the disease. In many individuals, seemingly disparate sensory-motor symptoms can be conceptualized as part and parcel of OCD. Sensory-motor aspects are discussed within the context of faulty information processing and related to neuropsychiatric systems characteristic of OCD. As the pathophysiology of OCD is highly extensive, not all sensory-motor symptoms discussed here will be observed in every individual.

BackgroundFor more than 15 years, deep brain stimulation (DBS) has served as a last-resort treatment for severe treatment-resistant obsessive-compulsive disorder (OCD).MethodsFrom 2010 to 2016, 20 patients with OCD (10 men/10 women) were included in a single-centre trial with a naturalistic open-label design over 1 year to evaluate the effects of DBS in the anterior limb of the internal capsule and nucleus accumbens region (ALIC-NAcc) on OCD symptoms, executive functions, and personality traits.ResultsALIC-NAcc-DBS significantly decreased OCD symptoms (mean Yale-Brown Obsessive Compulsive Scale reduction 33%, 40% full responders) and improves global functioning without loss of efficacy over 1 year. No significant changes were found in depressive or anxiety symptoms. Our study did not show any effect of ALIC-NAcc-DBS on personality traits or executive functions, and no potential outcome predictors were identified in a post hoc analysis. Other than several individual minor adverse events, ALIC-NAcc-DBS has been shown to be safe, but 35% of patients reported a sudden increase in anxiety and anhedonia after acute cessation of stimulation.ConclusionsWe conclude that ALIC-NAcc-DBS is a well-tolerated and promising last-resort treatment option for OCD. The cause of variability in the outcome remains unclear, and the aspect of reversibility must be examined critically. The present data from one of the largest samples of patients with OCD treated with DBS thus far support the results of previous studies with smaller samples.
