Prevalence and Correlates of the Concurrence of Autism Spectrum Disorder and Obsessive Compulsive Disorder in Children and Adolescents: A Systematic Review and Meta-Analysis.

Autism spectrum disorder (ASD) and obsessive compulsive disorder (OCD) are two common and impairing neurodevelopmental conditions with partial symptomatic overlap. The aim of this study is to systematically and meta-analytically examine the following: (i) the prevalence of an OCD diagnosis among young people with ASD, (ii) the prevalence of an ASD diagnosis among young people with OCD, and (iii) the clinical and therapeutic implications of such comorbidity. A multistep literature search was performed from database inception until 17 November 2023. This PRISMA/MOOSE-compliant systematic review, registered in PROSPERO (CRD42023480543), identified studies reporting on the prevalence, sociodemographic, psychopathologic, prognostic, and therapeutic correlates of OCD and ASD concurrence in children and adolescents. A quantitative meta-analysis with random effects was conducted to analyse the pooled prevalence of OCD among samples with a mean age of < 18 years old with ASD and the prevalence of ASD among individuals under 18 with OCD. Sensitivity analyses were performed to investigate the effect of diagnostic criteria and different continents. Meta-regression analyses were conducted to examine the effect of gender, age, IQ, and OCD severity scores. A narrative review of the clinical and therapeutical implications of the comorbidity was provided. 42 studies were selected for the systematic review (SR), and 31 of them were also included in one of the meta-analyses. The pooled prevalence of OCD among ASD youth samples (n = 8916, mean age = 10.6 ± 1.6; 16.4% female) was 11.6% (95% confidence intervals [CI] = 6.9%; 18.8%), and the pooled prevalence of ASD among OCD children and adolescent samples (n = 6209, mean age = 14.1 ± 1.4; 45.7% female) was 9.5% (95% CI = 6.0%; 14.7%). Meta-regressions found a statistically higher prevalence of ASD among samples with a lower prevalence of females (β = -4.7; 95%CI = -8.6; -0.8). Children with both OCD and ASD present higher rates of functional impairment, psychopathology, and other comorbidities, compared to youth with either of the disorders alone. OCD and ASD are highly concurrent conditions in youth, with symptomatic, prognostic, severity, and therapeutic implications. Future research should focus on conducting longitudinal cohort studies prospectively to determine development trajectories, along with randomized controlled trials to assess the efficacy of specific therapeutic interventions.

The association between childhood trauma and motor structure in obsessive-compulsive rituals: An ethological and evolutionary approach.

Ethological models have highlighted a specific motor structure of compulsions in obsessive-compulsive disorder (OCD), based on the rigid repetitions of acts, and with the adaptive significance of facing unpredictable conditions. Such an evolutionary mechanism might explain the robust association between childhood traumatic experiences (CTEs) and OCD. However, a relationship between CTEs and the motor structure of compulsions has not been investigated yet. The first objective of the study was to confirm a specific motor structure of OCD compulsions with respect to control behaviors; the second objective was to assess a possible association between the motor structure of compulsions and CTEs severity. Thirty-two OCD outpatients (13 female, Mage = 44.50 years, SE = 19.71) and 27 healthy controls (10 female, Mage = 37.62 years, SE = 16.20), matched for sex and age, provided a videotape of their compulsions and corresponding ordinary acts, respectively. Behavior was scored with the software "Observer." Participants were administered the Yale-Brown Obsessive Compulsive Scale and the Childhood Trauma Questionnaire. A dependent t test was used to compare the motor structure of behavior between the groups; Pearson's correlations to investigate associations between motor parameters and CTEs. Compulsions showed a specific motor structure due to the repetition of functional and nonfunctional acts. CTEs severity was especially associated with the repetition of functional acts, independently from OCD severity. Our findings, in confirming a peculiar motor structure for OCD compulsions, hint for the first time at a link between CTEs and compulsive repetition of functional acts, which would represent a plastic developmental response to CTEs unpredictability.

Paradigms and Practice Shifts: A Topical Narrative Review of the Evolving Face of Exposure-Based Treatment for Youth

Abstract: Exposure therapy is the gold standard treatment for anxiety and obsessivecompulsive disorders in children, adolescents, and adults. Inhibitory Learning Theory offers a nuanced and advanced perspective on exposure treatment positing that violating threat expectancies is more important than habituation. This paper highlights the effectiveness of inhibitory learning theory-guided exposure procedures for youth with anxiety and OCD, chronic pain, and eating disorders. A topical review focusing on the theoretical foundations of inhibitory learning theory, crucial augmentations of the approach, and outcomes with pediatric patients diagnosed with anxiety, eating, and pain disorders is presented. The literature review indicated that inhibitory learning theory-driven exposure produced beneficent outcomes in the identified populations. Various limitations and future directions were discussed. Limitations notwithstanding, inhibitory learning theory-led exposure represents a viable treatment option for pediatric patients with anxiety, eating, and chronic pain disorders.

Obsessive–Compulsive Disorder in Children and Adolescents

Obsessive–compulsive disorder (OCD) in children and adolescents is a neurobehavioral condition that can lead to functional impairment in multiple domains and decreased quality of life. We review the clinical presentation, diagnostic considerations, and common comorbidities of pediatric OCD. An overview of the biological and psychological models of OCD is provided along with a discussion of developmental considerations in youth. We also describe evidence-based treatments for OCD in childhood and adolescence, including cognitive behavioral therapy (CBT) with exposure and response prevention (ERP) and pharmacotherapy. Finally, research evaluating the delivery of CBT in different formats and modalities is discussed, and we conclude with suggestions for future research directions. Expected final online publication date for the Annual Review of Clinical Psychology, Volume 20 is May 2024. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Pathways to suicidal risk in patients with OCD: The role of childhood abuse, cognitive vulnerabilities, OCD symptomology, and depression

Childhood maltreatment (CM) and its associated cognitive vulnerabilities, such as early maladaptive schemas (EMSs), have been identified as dysfunctional and risk factors for obsessive-compulsive disorder (OCD) and its related clinical outcomes, including obsessive-compulsive (OC) symptoms, depression, and suicidality. However, the combined effects of these variables on suicidal risk have not been investigated yet. This study aimed to examine the relationships between CM and suicidal risk through the paths of EMS domains, OCD symptoms, and depression in patients with OCD (n = 300). Participants completed a series of self-report scales assessing the psychological and clinical variables. The results showed a significant relationship between childhood emotional abuse and suicidal ideation, which was mediated by the paths of disconnection/rejection, unacceptable obsessional thoughts, and depression. These findings suggest that individuals with OCD who have experienced childhood emotional abuse may exhibit heightened levels of disconnection/rejection, frequent repugnant obsessions, and depressive mood, possibly contributing to an increased risk of suicide. Therefore, it is crucial for therapeutic settings, such as schema therapy, to carefully assess and monitor these risk factors in order to prevent suicidal risk in individuals with OCD.

Calcification of the Pineal Gland and Psychopathology in Obsessive-Compulsive Disorder in Children and Adolescents: A Clinical Case Study

While it is generally believed that they result from the interaction of genetic and environmental factors, some cases of obsessive-compulsive disorder (OCD) can be attributed to specific neurological etiologies. Hence, the interest of this article, which discusses the case of a 13-year-old child, who has been experiencing sleep disturbances since early childhood and is seeking treatment for an obsessive syndrome with severe symptoms and a poor therapeutic response. An assessment revealed the presence of pineal gland calcification. Despite the patient being placed on a suitable treatment for obsessive-compulsive disorder, their symptoms only improved after the addition of melatonin, resulting in a significant enhancement in both their sleep and obsessive-compulsive symptoms on the Yale-Brown Scale. Thus, this article highlights the role of the pineal gland in melatonin secretion and also discusses the role of this hormone in the occurrence of mental disorders as well as its therapeutic attributes in psychiatry.

Therapist guided, parent-led cognitive behavioural therapy (CBT) for pre-adolescent children with obsessive compulsive disorder (OCD): a non-concurrent multiple baseline case series.

Cognitive behavioural therapy (CBT) including exposure and response prevention (ERP) is an effective treatment for preadolescent children with obsessive compulsive disorder (OCD); however, there is a need to increase access to this treatment for affected children. This study is a preliminary evaluation of the efficacy and acceptability of a brief therapist-guided, parent-led CBT intervention for pre-adolescent children (5-12 years old) with OCD using a non-concurrent multiple baseline approach. Parents of 10 children with OCD were randomly allocated to no-treatment baselines of 3, 4 or 5 weeks before receiving six to eight individual treatment sessions with a Psychological Wellbeing Practitioner. Diagnostic measures were completed prior to the baseline, 1-week post-treatment, and at a 1-month follow-up, and parents completed weekly measures of children's OCD symptoms/impairment. Seventy percent of children were 'responders' and/or 'remitters' on diagnostic measures at post-treatment, and 60% at the 1-month follow-up. At least 50% of children showed reliable improvements on parent-reported OCD symptoms/impairment from pre- to post-treatment, and from pre-treatment to 1-month follow-up. Crucially, the intervention was acceptable to parents. Brief therapist-guided, parent-led CBT has the potential to be an effective, acceptable and accessible first-line treatment for pre-adolescent children with OCD, subject to the findings of further evaluations.

Comorbid OCD and ADHD in youth: Clinical implications and treatment recommendations

Obsessive compulsive disorder (OCD) affects up to 4% of children and adolescents (Nazeer et al., 2020). Childhood OCD impairs overall quality of life, particularly in familial, social and academic settings. For individuals with OCD, obsessions — unwanted, intrusive thoughts, images, or impulses that cause distress are subsequently reduced by compulsions — behaviors that are designed to assuage the distress of the obsessions, according to set rules or senses of completion (American Psychiatric Association, 2013). Common obsessions surround core fears of harm avoidance, disgust and/or a sense of incompleteness, leading to common compulsions of repeating, checking, avoidance, and/or other rituals.

Parents’ experience and views on the assessment and treatment of children with OCD within the public mental health system in Iceland: a qualitative study

Purpose Obsessive-compulsive disorder (OCD) in children can lead to long-lasting symptoms and access to evidence-based evaluation and treatment is crucial for its prevention. In Iceland, the law guarantees public access to the highest quality healthcare services. To date, no study has evaluated the services available for children with OCD within the national healthcare system (NMHS). This qualitative study explored the experiences of parents navigating the Icelandic NMHS for their children with OCD. Method and materials Seven parents who had sought services within the NMHS for their children diagnosed with OCD at private clinics were interviewed using a semi-structured interview. The responses were analyzed using thematic framework analysis. Results Nineteen themes were identified, including three overarching themes and eight overarching sub-themes, and eight sub-themes within them. A prevalent theme was the giving up on the national mental healthcare system due to parents’ experiences of accessing mental healthcare for their children being challenging. Other issues faced by parents included a lack of knowledge on where to seek help, inadequate evaluation of the issue, and the lack of access to psychotherapy for their children. The healthcare workers’ responses and recommendations also resulted in parents seeking treatment at private clinics. Conclusions These findings underscore the need for clearer pathways for seeking help, improved access to trained healthcare workers, and a more centralized evaluation process. These insights can potentially guide future research and policy decisions to better support families dealing with childhood OCD in Iceland.

Clinician perspectives on levels of evidence and oversight for deep brain stimulation for treatment-resistant childhood OCD

Approximately 10–20% of children with obsessive-compulsive disorder (OCD) have treatment-resistant presentations, and there is likely interest in developing interventions for this patient group, which may include deep brain stimulation (DBS). The World Society for Stereotactic and Functional Neurosurgery has argued that at least two successful randomized controlled trials should be available before DBS treatment for a psychiatric disorder is considered “established.” The FDA approved DBS for adults with treatment-resistant OCD under a humanitarian device exemption (HDE) in 2009, which requires that a device be used to manage or treat a condition impacting 8000 or fewer patients annually in the United States. DBS is currently offered to children ages 7 and older with treatment-resistant dystonia under an HDE. Ethical and empirical work are needed to evaluate whether and under what conditions it might be appropriate to offer DBS for treatment-resistant childhood OCD. To address this gap, we report qualitative data from semi-structured interviews with 25 clinicians with expertise in this area. First, we report clinician perspectives on acceptable levels of evidence to offer DBS in this patient population. Second, we describe their perspectives on institutional policies or protocols that might be needed to effectively provide care for this patient population.

A Randomized Controlled Trial of OC-Go for Childhood Obsessive–Compulsive Disorder: Augmenting Homework Compliance in Exposure With Response Prevention Treatment

The current study investigates a novel digital tool designed to address barriers to out-of-session homework adherence in exposure with response prevention (ERP) for child obsessive-compulsive disorder (OCD). The OC-Go platform allows clinicians to create and push tailored interactive protocol- or symptom-specific assignments to patients on their mobile devices, providing in-the-moment step-by-step directions, encouragement, accountability, and a sense of therapeutic presence for patients during out-of-office exposures. The platform also facilitates objective measurement of homework and allows providers to support one another through a shared and searchable crowdsourced library with hundreds of assignable exposures and psychoeducation activities for specific OCD symptoms. The current study tested the usability and feasibility of the OC-Go platform with ERP stakeholders (OCD therapists, patients, and parents; N = 172) using the System Usability Scale (SUS). The study also tested the efficacy of OC-Go for augmenting homework adherence and clinical response using a randomized controlled, crossover design in a sample of 28 treatment-seeking youth with OCD. Participants randomized to standard ERP exhibited a homework adherence rate of 68.4% (95% CI [65.6, 71.0]), those randomized to ERP with OC-Go exhibited a greater adherence rate of 83.3% (95% CI [80.8, 85.6], p < .001). Both groups experienced large declines in Children’s Yale–Brown Obsessive–Compulsive Scale-rated OCD (d = 1.31, p < .001), though participants randomized to begin ERP with OC-Go exhibited clinically significant greater improvement (p = .05), translating into an additional augmented treatment response at the Week 6 primary end point (d = 0.36) and the Week 12 treatment end point (d = 0.72). Stakeholders rated OC-Go in the 90th percentile for usability on the SUS, indicative of a highly usable and easy-to-learn technology. Initial evidence supports OC-Go as a feasible and effective adjunct to improve out-of-office exposure measurement, adherence, and treatment response in ERP for child OCD.

Closing the Gap for Children with OCD: A Staged-Care Model of Cognitive Behavioural Therapy with Exposure and Response Prevention

Childhood obsessive–compulsive disorder (OCD) is among the most prevalent and disabling mental health conditions affecting children and adolescents. Although the distress and burden associated with childhood OCD are well documented and empirically supported treatments are available, there remains an unacceptable “treatment gap” and “quality gap” in the provision of services for youth suffering from OCD. The treatment gap represents the large number of children who never receive mental health services for OCD, while the quality gap refers to the children and young people who do access services, but do not receive evidence-based, cognitive behavioural therapy with exposure and response prevention (CBT-ERP). We propose a novel staged-care model of CBT-ERP that aims to improve the treatment access to high-quality CBT-ERP, as well as enhance the treatment outcomes for youth. In staged care, patients receive hierarchically arranged service packages that vary according to the intensity, duration, and mix of treatment options, with provision of care from prevention, early intervention, through to first and second-line treatments. Based on a comprehensive review of the literature on treatment outcomes and predictors of treatments response, we propose a preliminary staging algorithm to determine the level of clinical care, informed by three key determinants: severity of illness, comorbidity, and prior treatment history. The proposed clinical staging model for paediatric OCD prioritises high-quality care for children at all stages and levels of illness, utilising empirically supported CBT-ERP, across multiple modalities, combined with evidence-informed, clinical decision-making heuristics. While informed by evidence, the proposed staging model requires empirical validation before it is ready for prime time.

Obsessive-compulsive disorders in children and adolescents

Zwangsstörungen bestehen aus Zwangsgedanken bzw. einem Unvollständigkeits- oder „Nicht-genau-richtig“-Erleben, Zwangsritualen und Vermeidungsverhalten. In der Diagnostik werden die wesentlichen Aspekte der Zwangsstörung erfasst. Sie umfasst zudem ein strukturiertes Interview und eine Verhaltensanalyse. Empirische Wirksamkeitsnachweise liegen nur für die Kognitive Verhaltenstherapie (KVT) und die Gabe von selektiven Serotonin-Wiederaufnahmehemmern vor. Die wesentliche Intervention in der KVT ist die Exposition mit Reaktionsverhinderung. Diese folgt traditionell einem Habituationsrational oder in den letzten Jahren zunehmend dem Rational des Inhibitionslernens. Ergänzend können kognitive und metakognitive Interventionen erfolgen. Familienbezogene Interventionen dienen insbesondere dem Abbau der familiären Akkommodation.

The infected and the affected: A longitudinal study of the impact of the COVID-19 pandemic on schoolchildren in Florida.

To identify risk factors associated with symptoms of anxiety, depression, and obsessive-compulsive disorder (OCD) among children during the 1st year of the COVID-19 pandemic. A longitudinal study with three cross-sectional timepoints [April 2020 (n = 273), October 2020 (n = 180), and April 2021 (n = 116)] was conducted at a K-12 public school in Florida. Infection and sero-positivity for SARS-CoV-2 was determined by molecular and serologic approaches. Adjusted odds ratios using mixed effect logistic regression models for symptom-derived indicators of anxiety, depression, and OCD in children in April 2021 are presented; past infection and seropositivity were included in the models. The prevalence of anxiety, depression, or OCD moved from 47.1, to 57.2, to 42.2% across the three timepoints during the study. By endline of the study, in April 2021, non-white children were at higher risk for depression and OCD. Risk for anxiety, depression, and OCD was associated with students who lost a family member due to COVID-19 and who were identified as at-risk in previous timepoints. Rates of SARS-CoV-2 infection and seropositivity were low and not statistically associated with assessed outcomes. In situations like the COVID-19 pandemic, targeted mental health interventions and screenings are needed in children and adolescents, especially among minority children.

Early Identification and Intervention in Pediatric Obsessive-Compulsive Disorder.

Obsessive-compulsive disorder (OCD) is a psychiatric disorder characterized by persistent thoughts with subsequent repetitive behaviors. Interventions that are effective for adult OCD cannot simply be generalized to pediatric OCD, since OCD in children and adolescents usually has a different clinical presentation, etiology and course from adult OCD. Delayed and inadequate treatment is associated with a worse prognosis, making the need for early identification and intervention in pediatric OCD very urgent. In this paper, we reflected on the current constraints that make early interventions for pediatric OCD unpromoted and reviewed the approaches with potential application for early identification and early intervention in pediatric OCD, categorized by three-level prevention stages corresponding to a clinical staging model. Since the etiology of pediatric OCD is still unclear, primary prevention is most lacking, and early interventions for pediatric OCD are currently focused on the secondary prevention stage, which aims to prevent the conversion of obsessive-compulsive symptoms into full-blown OCD; tertiary prevention mostly focuses on the alleviation of mild to moderate OCD, while interventions for co-morbidities are still in their infancy. We closed by considering the important research questions on this topic.

The Relationship Between Adverse Childhood Experiences, Symptom Severity, Negative Thinking, Comorbidity, and Treatment Response in Youth with Obsessive-Compulsive Disorder.

Although youth and adults with obsessive-compulsive disorder (OCD) endorse elevated incidence of exposure to traumatic life events during childhood, the existing literature on adverse childhood experiences (ACEs) and OCD is mixed and studies focusing on pediatric OCD are limited. The present study examines the relationship between ACEs and OCD onset, symptom severity, negative cognitive patterns, comorbidity, and cognitive-behavioral therapy (CBT) response in 142 children and adolescents with OCD. ACEs were ascertained from parent reports. Most parents reported child exposure to ACEs. Out of the parents who reported ACEs, 50% reported ACE exposure prior to OCD diagnosis and 50% reported ACE exposure after OCD diagnosis. No significant associations between ACEs and comorbidity or CBT response were found, suggesting that CBT for pediatric OCD is effective regardless of ACE exposure. Family financial problems were associated with increased obsessive-compulsive symptom severity and negative thinking. Implications for research and practice are discussed.

Psychotherapy for co-occurring symptoms of depression, anxiety and obsessive-compulsive disorder in children and adults with autism spectrum disorder: a systematic review and meta-analysis.

Individuals with autism spectrum disorder (ASD) struggle accessing psychotherapy services for comorbidities, including anxiety-, depressive- and obsessive-compulsive disorders (OCD). Apart from cognitive behavioural therapy (CBT) for anxiety in children with ASD, it is unclear whether psychotherapy is effective for these comorbid disorders.We therefore systematically reviewed any form of psychotherapy for co-occurring symptoms of anxiety, depression and OCD in individuals with ASD.Database searches were conducted until February 2022 using EMBASE, PsycINFO and PubMed. Randomised controlled trials (RCT) were included investigating any form of psychotherapy for symptoms of anxiety, depression and OCD in individuals with ASD. Summary data were extracted, and random-effects meta-analyses were conducted.For CBT 26 RCTs (n = 1251), and for social skills training (SST) 11 RCTs (n = 475) met criteria for inclusion. Pooled effect sizes indicated a moderate reduction of anxiety in children (g = -0.70) and a small reduction of depressive symptoms in adults (g = -0.39). For SST overall effect sizes were small for reduction of anxiety in children (g = -0.35) and adults (g = -0.34) and moderate for reduction of depressive symptoms in children (g = -0.50). Risk of bias was high in 18, moderate in 16 and low in 3 RCTs.Our results provide new and age-specific evidence that: (1) CBT is effective for reducing anxiety in children and to a lesser extent for depressive symptoms in adults with ASD; and (2) social skills interventions are effective for reducing anxiety in children and adults and for depressive symptoms in children with ASD.

Family-based cognitive behavioural therapy versus family-based relaxation therapy for obsessive-compulsive disorder in children and adolescents (the TECTO trial): a statistical analysis plan for the randomised clinical trial

BackgroundObsessive-compulsive disorder (OCD) is a debilitating psychiatric disorder which affects up to 3% of children and adolescents. OCD in children and adolescents is generally treated with cognitive behavioural therapy (CBT), which, in more severely affected patients, can be combined with antidepressant medication. The TECTO trial aims to compare the benefits and harms of family-based CBT (FCBT) versus family-based psychoeducation/relaxation training (FPRT) in children and adolescents aged 8 to 17 years. This statistical analysis plan outlines the planned statistical analyses for the TECTO trial.MethodsThe TECTO trial is an investigator-initiated, independently funded, single-centre, parallel-group, superiority randomised clinical trial. Both groups undergo 14 sessions of 75 min each during a period of 16 weeks with either FCBT or FPRT depending on the allocation. Participants are randomised stratified by age and baseline Children’s Yale–Brown Obsessive-Compulsive Scale (CY-BOCS) score. The primary outcome is the CY-BOCS score. Secondary outcomes are health-related quality of life assessed using KIDSCREEN-10 and adverse events assessed by the Negative Effects Questionnaire (NEQ). Primary and secondary outcomes are assessed at the end of the intervention. Continuous outcomes will be analysed using linear regression adjusted for the stratification variables and baseline value of the continuous outcome. Dichotomous outcomes will be analysed using logistic regression adjusted for the stratification variables. The statistical analyses will be carried out by two independent blinded statisticians.DiscussionThis statistical analysis plan includes a detailed predefined description of how data will be analysed and presented in the main publication before unblinding of study data. Statistical analysis plans limit selective reporting bias. This statistical analysis plan will increase the validity of the final trial results.Trial registrationClinicalTrials.gov NCT03595098.

Genetic Susceptibility of Obsessive-Compulsive Disorder in The Paediatric Population

Obsessive-compulsive disorder (OCD) is a psychiatric disorder involving recurring, unwanted thoughts followed by eliciting ritualistic behaviours to alleviate feelings of distress. Two onsets of OCD exist: early and late. Early-onset (also known as paediatric or childhood) OCD shows greater rates of comorbidities and symptom severity, as well as stronger links to genetics, which are a developing field in OCD etiopathogenesis. An extensive number of twin and family studies have demonstrated heritability of OCD and clustering in families. Although genome-wide association studies (GWAS) are a relatively new addition to the progression of OCD genomics, they have provided initial results on specific candidate genes involved. Currently, the serotonergic, early glutamatergic, and dopaminergic systems possess the main genes implicated in OCD. An epigenetic contribution has also been recently considered in paediatric populations. This review of existing literature primarily focuses on the genetic factors of OCD, particularly its early-onset form.

Cytokine profile of pediatric patients with obsessive-compulsive and/or movement disorder symptoms: A review.

Cytokines are an important modulator of the immune system and have been found to be altered significantly in many neurological and psychiatric disorders, like obsessive compulsive disorder (OCD) and movement disorders. Also, in pediatric autoimmune neuropsychiatric disorders associated with group A streptococcal infections (PANDAS), which are characterized by abrupt debut of symptoms of OCD and /or movement disorder symptoms, alterations in the immune system have been suggested. The aim of this paper was to review the current literature on the cytokine profile of pediatric patients with symptoms of OCD and/or movement disorder symptoms. A search of PubMed and Medline was performed with specific keywords to review studies measuring cytokines in pediatric patients with symptoms of OCD and/or movement disorders. Nineteen studies were found, twelve of which included a healthy control group, while four studies had control groups of children with other disorders, primarily neurological or psychiatric. One study compared cytokines measurements to reference intervals, and two studies had a longitudinal design. Many cytokines were found to have significant changes in patients with symptoms of OCD and/or movement disorders compared to both healthy controls and other control groups. Furthermore, differences were found when comparing cytokines in periods of exacerbation with periods of remission of symptoms in study participants. The cytokines that most studies with healthy control groups found to be significantly altered were TNF-α, IL-1β and IL-17. Although the exact role of these cytokines in OCD and movement disorder symptoms remains unclear, the available literature suggests a proinflammatory cytokine profile. This offers interesting perspectives on the pathogenesis of OCD and/or movement disorder symptoms in children, and further research into the implications of cytokines in neuropsychiatric disorders is warranted.
