Compulsive Disorder

People with Obsessive Compulsive Disorder (OCD) experience unpleasant and intrusive thoughts, images, doubts or urges (called obsessions) and repetitive behaviours (called compulsions). Compulsions are usually carried out as a way of reducing the distress caused by obsessions. OCD takes many different forms and causes distress and interference to day-to-day life.

Polygenic Scores

Clinical, epidemiological, and genetic findings support an overlap between eating disorders, obsessive-compulsive disorder (OCD), and anxiety symptoms. However, little research has examined the role of genetic factors in the expression of eating disorders and OCD/anxiety phenotypes. We examined whether the anorexia nervosa (AN), OCD, or AN/OCD transdiagnostic polygenic scores (PGS) predict eating disorders, OCD, and anxiety symptoms in a large population-based developmental cohort. Using summary statistics files from the Psychiatric Genomics Consortium Freeze 2 AN and Freeze 1 OCD GWAS, we first conducted an AN/OCD transdiagnostic GWAS meta-analysis and then calculated PGS for AN, OCD, and AN/OCD in participants from the Avon Longitudinal Study of Parents and Children with available genetic and phenotype data on eating disorder, OCD, and anxiety diagnoses and symptoms (sample size 3,212-5,369 per phenotype). We observed sex differences in the PGS prediction of eating disorder, OCD, and anxiety-related phenotypes, with AN genetic risk manifesting at an earlier age and playing a more prominent role in eating disorder phenotypes in boys than in girls. Compulsive exercise was the only phenotype predicted by all three PGS (e.g., PAN(boys)=0.0141 at age 14; POCD(girls)=0.0070 at age 16; PAN/OCD(all)=0.0297 at age 14). Our results suggest that earlier detection of eating disorder, OCD, and anxiety-related symptoms could be made possible by including measurement of genetic risk for these psychiatric conditions while being mindful of sex differences.

Unified Protocol

The case of a 25-year-old male with obsessive-compulsive disorder (OCD) is presented in this chapter. The patient, “Luke,” had primary obsessions related to harm befalling his family and girlfriend, as well as fears of contamination. His primary compulsions included mental “undoing,” in his words, and repeating actions. He engaged in significant avoidance around potential contaminants. The text reviews Luke’s course of treatment with the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP), including the application of each treatment module and attention to challenging issues that arose in this case. Specific attention is devoted to the use of cognitive reappraisal in the UP for OCD, managing symptom accommodation by family members, and exposure in the context of intrusive thoughts and mental rituals.

Obsessive-compulsive disorder (OCD) is characterized by cognitive regulation deficits. However, the current literature has focused on executive functioning and emotional response impairments in this disorder. Herein, we conducted a systematic review of studies assessing the behavioral, physiological, and neurobiological alterations in cognitive regulation in obsessive-compulsive patients using the PubMed database. Most of the studies included explored behavioral (distress, arousal, and frequency of intrusive thoughts) and neurobiological measures (brain activity and functional connectivity) using affective cognitive regulation paradigms. Our results pointed to the advantageous use of reappraisal and acceptance strategies in contrast to suppression to reduce distress and frequency of intrusive thoughts. Moreover, we observed alterations in frontoparietal network activity during cognitive regulation. Our conclusions are limited by the inclusion of underpowered studies with treated patients. Nonetheless, our findings support the OCD impairments in cognitive regulation of emotion and might help to improve current guidelines for cognitive therapy.

Significant Difference

Objective. The purpose of this study was to compare the prevalence of comorbid eating disorders in Obsessive-Compulsive Disorder (OCD) and other common anxiety disorders.Method. 179 patients from the same geographical area with a diagnosis of OCD or an anxiety disorder were divided into two groups based on their primary diagnosis. The prevalence of a comorbid eating disorder was calculated in both groups.Results. There was no statistically significant difference in the prevalence of comorbid eating disorders between the OCD and other anxiety disorders group.Conclusions. These results suggest that the prevalence of comorbid eating disorders does not differ in anxiety disorders when compared with OCD. However, in both groups, it remains statistically higher than that of the general population.
