Obsessive Compulsive Disorders

The therapy manuals included in this volume—the Unified Protocols for Transdiagnostic Treatment of Emotional Disorders in Children (UP-C) and Adolescents (UP-A)—include evidence-based treatment strategies to assist child and adolescent clients to function better in their lives. The manuals include specific guidelines for treatment delivery, and they also contain information about how to introduce parent-directed strategies to help promote long-term uptake of youth-directed therapy skills. The evidence-based treatment skills presented may be applied by therapists to children and adolescents with a wide variety of emotional disorders. This treatment guide takes a transdiagnostic approach to the treatment of emotional disorders. Some of the disorders that may be targeted include anxiety disorders and depressive disorders. This treatment is flexible enough for use with some trauma and stress-related disorders (including adjustment disorders), somatic symptom disorders, tic disorders and obsessive-compulsive disorders. The transdiagnostic presentation of evidence-based intervention techniques within these treatments may be particularly useful for children and adolescents presenting with multiple emotional disorders or mixed/subclinical symptoms of several emotional disorders.

Compulsive Disorders

Autism Spectrum Disorder (ASD) is a pervasive developmental disorder, that is raising at a concerning rate. However, underlying mechanisms are still to be discovered. Obsessions and compulsions are the most debilitating aspect of these disorders (OCD), and they are the treatment priority for patients. SAPAP3 knock out mice present a reliable mouse model for repetitive compulsive behavior and are mechanistically closely related to the ASD mouse model Shank3 on a molecular level and AMPA receptor net effect. The phenotype of SAPAP3 knock out mice is obsessive grooming that leads to self-inflicted lesions by 4 months of age. Recent studies have accumulated evidence, that epigenetic mechanisms are important effectors in psychiatric conditions such as ASD and OCD. Methylation is the most studied mechanism, that recently lead to drug developments for more precise cancer treatments. We injected SAPAP3 mice with an epigenetic demethylation drug RG108 during pregnancy and delayed the onset of the phenotype in the offspring by 4 months. This result gives us clues about possible mechanism involved in OCD and ASD. Additionally, it shows that modulation of methylation mechanisms during development might be explored as a preventative treatment in the cases of high inherited risk of certain mental health conditions.

Behavioral flexibility is the ability of a subject to change its behavior according to contextual cues. In humans, Obsessive Compulsive Disorders (OCD) is characterized by repetitive behavior, performed through rigid rituals. This phenomenological observation has led to explore the idea that OCD patients may have diminished behavioral flexibility. To address this question we developed innovative translational approaches across multiple species, including human patients suffering from obsessive-compulsive disorders, and rodent genetic models of OCD to provide original data in the perspective of enlightening the neurocognitive bases of compulsive behaviors. Behavioral flexibility may be challenged in experimental tasks such as reversal learning paradigms. In these tasks, the subject has to respond to either of two different visual stimuli but only one stimulus is positively rewarded while the other is not. After this first association has been learned, reward contingency are inverted, so that the previously neutral stimulus is now rewarded, while the previously rewarded stimulus is not. Performance in reversal learning is indexed by the number of perseverative errors committed when participants maintain their response towards previously reinforced stimulus in spite of negative reward. Unsurprisingly, this behavioral task has been adapted to mice using various response modalities (T-maze, lever press, nose-poke). Using animal models of compulsive behaviors give much more possibilities to study the deficient functions and their underlying neural basis that could lead to pathological repetitive behaviors. Here we present new behavioral set-ups that we developed in parallel in human (i.e. healthy subjects and OCD patients) and mice (i.e. controls and SAPAP3-KO mice) to study the role of the behavioral flexibility as a possible endophenotype of OCD. We observed that the subjects suffering of compulsive behaviors showed perseverative maladaptive behaviors in these tasks. By comparing the results of a similar task-design in humans and mouse models we will discuss the pertinence of such translational approach to further study the neurocognitive basis of compulsive behaviors.
