Circadian Rhythms in Obsessive-Compulsive Disorder: Recent Findings and Recommendations for Future Research

AbstractPurpose of ReviewCircadian rhythms are a topic of growing interest in mental health, particularly in obsessive-compulsive disorder. However, the consistency of this link has not been carefully examined. Thus, the present review integrates findings from the past 5  years in order to determine the strength of such a relationship and identify areas for clarification and extension.Recent FindingsFindings revealed inconsistent evidence for a link between circadian rhythms and OCD. Chronotype is unrelated to OCD symptoms in adolescents but predicts OCD symptoms in adults. Results on delayed sleep timing are equivocal. Circadian rhythm disorders predict OCD treatment outcome. Preliminary evidence implicates decreased light exposure and diurnal symptom variability in OCD.SummaryThe relationship between circadian rhythms and OCD may vary by age, diagnostic status, and assessment method. Recent findings are limited by an overreliance on convenience samples and singular self-report methods. Recommendations for future research on the role of circadian rhythms in OCD are discussed.

Abstract Cannabidiol (CBD) and Δ9-tetrahydrocannabinol (THC) are the most represented phytocannabinoids in Cannabis sativa plants. However, CBD may present with a different activity compared with the psychotomimetic THC. Most typically, CBD is reported to be used in some medical conditions, including chronic pain. Conversely, the main aim of this systematic review is to assess and summarise the available body of evidence relating to both efficacy and safety of CBD as a treatment for psychiatric disorders, alone and/or in combination with other treatments. Eligible studies included randomized controlled trial...

PURPOSE OF REVIEW The purpose of this article is to present current information on the phenomenology, epidemiology, comorbidities, and pathophysiology of tic disorders and discuss therapy options. It is hoped that a greater understanding of each of these components will provide clinicians with the necessary information to deliver thoughtful and optimal care to affected individuals. RECENT FINDINGS Recent advances include the finding that Tourette syndrome is likely due to a combination of several different genes, both low-effect and larger-effect variants, plus environmental factors. Pathophysiologically, increasing e...

Authors: Berardelli I, Belvisi D, Pasquini M, Fabbrini A, Petrini F, Fabbrini G Abstract Introduction: reviewed studies that assessed the treatment of psychiatric disturbances in Parkinson's disease and atypical parkinsonisms. Neuropsychiatric disturbances in these conditions are frequent and have a profound impact on quality of life of patients and of their caregivers. It is therefore important to be familiar with the appropriate pharmacological and non-pharmacological interventions for treating these disorders.

In conclusion, this review highlights the importance for clinicians to investigate for the presence of chronic nightmares along with other sleep difficulties (most commonly, insomnia and sleep apnea), to consider the potential influence of nightmares on the course of the primary mental disorder, and to be prepared to grant access to treatments targeting nightmares.

Abstract High rates of delayed sleep phase disorder have been observed in inpatients with obsessive compulsive disorder (OCD). Up to one-third of patients with OCD do not respond to treatment; therefore, new interventions or methods of enhancing current interventions are imperative. The theory of inpatient circadian care (TICC) posits that enhancing inpatient settings through environmental changes, such as, a set lights out time and consistent scheduling may facilitate symptom improvements in both medical and psychiatric illnesses. Symptom improvements related to these environmental changes have yet to be explored...

We present the case of a 13 year old boy with an unusual presentation of OCD. He presented with irritability, aggression, poor sleep, reduced attention, hyperreligiosity, social withdrawal and disinhibition (i.e. inappropriately touching females) for 1 week and was found to have obsessional thoughts and impulses related to sex and the compulsion of seeking absolution from lord buddha. He was diagnosed as OCD after excluding organic causes, manic episode, acute psychotic episode, drug induced psychosis and sexual abuse. He initially responded to fluoxetine 20mg, olanzapine 2.5 and a short course of lorazepam. He was functio...
