Abstract
Hoarding behavior is prevalent in children and adolescents, yet clinicians do not routinely inquire about it and youth may not spontaneously report it due to stigma. It is unknown whether hoarding behavior, over and above obsessive-compulsive symptoms (OCS), is associated with major clinical factors in a general youth population. This observational study included N = 7054 youth who were not seeking help for mental health problems (ages 11-21, 54% female) and completed a structured interview that included evaluation of hoarding behavior and OCS, as a part of the Philadelphia Neurodevelopmental Cohort between November 2009 and December 2011. We employed regression models with hoarding behavior and OCS (any/none) as independent variables, and continuous (linear regression) or binary (logistic regression) mental health measures as dependent variables. All models covaried for age, sex, race, and socioeconomic status. A total of 374 participants endorsed HB (5.3%), most of which reported additional OCS (n = 317). When accounting for OCS presence, hoarding behavior was associated with greater dimensional psychopathology burden (i.e., higher P-factor) (β = 0.19, p < .001), and with poorer functioning (i.e., lower score on the child global assessment scale) (β = - 0.07, p < .001). The results were consistent when modeling psychopathology using binary variables. The results remained significant in sensitivity analyses accounting for count of endorsed OCS and excluding participants who met criteria for obsessive-compulsive disorder (n = 210). These results suggest that hoarding behavior among youth is associated with poorer mental health and functioning, independent of OCS. Brief hoarding-behavior assessments in clinical settings may prove useful given hoarding behavior's stigma and detrimental health associations.

Abstract
Cognitive disengagement syndrome (CDS) has been found to be associated with internalizing symptoms. Yet, no study thus far has focused on whether there is an association between obsessive-compulsive disorder (OCD) and CDS. The purpose of this study is to examine the symptom frequency and clinical implications of CDS in children with OCD. The study included sixty-one children with OCD and sixty-six typically developing children. Children were evaluated by a semi-constructed diagnosis interview, Obsessive-Compulsive Inventory, Barkley Child Attention Scale, and Stroop test. The frequency of elevated symptoms of CDS, and total time, total error, and total correction scores of the Stroop test were significantly higher in the OCD group compared to the controls. Elevated CDS symptoms were significantly associated with higher OCD symptom prevalence and poorer performance on the Stroop Test. Moreover, poor insight, hoarding symptoms, mental compulsions, and ADHD comorbidity were significantly higher in those with elevated CDS symptoms than in those without CDS in the OCD group. The findings of this study provide clinical implications that CDS symptoms may contribute to deficits in attentional orientation, conceptual flexibility, and cognitive processing speed in OCD.

Abstract
Current research suggests obsessive-compulsive disorder (OCD) co-occurs in around 20% of people with hoarding disorder (HD). The article discusses the theoretical conceptualization of co-occurring HD and OCD (HD+OCD), highlighting similarities between the disorders that may contribute to comorbidity, such as potentially overlapping etiological factors, comorbidity profiles, and phenomenological aspects; and differences that are important to consider in differential diagnosis and conceptualization, such as belief patterns, ego-syntonicty/dystonicity, and trajectory. The combination of HD+OCD versus either disorder alone appears to be associated with a profile characterized by higher nonhoarding OCD symptoms, anxiety symptoms, depression, and tic disorders, and which may be more treatment-refractory. The authors discuss some commonly used measures to assess hoarding that may be relevant in the context of OCD, as differential diagnosis of hoarding behaviors is often difficult, and hoarding may be difficult to detect in patients with OCD, especially in children. The article ends with a discussion on considerations for the treatment of HD+OCD with cognitive-behavioral therapy, as hoarding symptoms are less likely to respond to gold-standard exposure and response prevention, and there are no established treatment protocols that are designed to treat co-occurring HD and OCD.

Abstract
Although hoarding symptoms are reported to begin in childhood and adolescence, the true prevalence of the disorder in this age group is unknown. This study aims to estimate the prevalence of hoarding disorder (HD) in children and adolescents. The present study was planned as a two-stage epidemiological research. In the first stage, the Children's Saving Inventory (CSI) and informed consent forms were delivered to a group of students' parents. In the second stage, one-on-one psychiatric interviews with a physician were planned with the families and children who had hoarding behavior (HB), as described by their parents. The DSM-5-based HD interview and the Development and Well-Being Assessment (DAWBA) diagnostic tool were used to detect prevalence of HD and comorbid psychiatric disorders. A total of 3249 children were included in the study, and 318 children and their parents were evaluated in the second stage. As a result of the second assessment, 32 out of 318 children met the HD diagnostic criteria. The estimated prevalence of HD was 0.98% (95% CI 0.7-1.4). Hoarding disorder was found more frequently in females (F/M = 3/1). After a logistic regression analysis, variables such as female sex and the presence of any psychopathology were identified as independent correlates of HD. More than half (56.2%) of the children diagnosed as having HD also had a comorbid psychiatric disorder. In the present study, the two-stage evaluation method was used in a large pediatric sample to determine the estimated prevalence of HD, as well as the factors associated with the disorder and comorbid psychiatric disorders.

Abstract
Tic disorders are neurological disorders that are prone to fluctuation and recurrence. It is important to study the factors related to disease recurrence and to subsequently provide suggestions for clinical treatment. A retrospective study was conducted to assess patients with recurrent and non-recurring tic disorders diagnosed in the Pediatric Tic Disorder Clinic of the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine, China, and to extract various factors—such as fetal status; medication, allergy, and family history; social and psychological factors; blood lead content; electroencephalogram (EEG); disease duration; type of tics; and disease severity—and identify factors associated with recurrence. The recurrence rate of tic disorders was approximately 45.10% in this study. The childbirth conditions, surgery/trauma, respiratory tract infection, allergy, stress, consumption of tiapride, and severity of tic disorders were factors related to and affected disease recurrence.

Abstract
OBJECTIVE In the present study, we aimed to perform a systematic review evaluating the cognitive performance of patients with hoarding disorder (HD) compared with controls. We hypothesized that HD patients would present greater cognitive impairment than controls. METHODS A systematic search of the literature using the electronic databases MEDLINE, SCOPUS, and LILACS was conducted on May 2020, with no date limit. The search terms were "hoarding disorder," "cognition," "neuropsychology," "cognitive impairment," and "cognitive deficit." We included original studies assessing cognitive functioning in patients with HD. RESULTS We retrieved 197 studies initially. Of those, 22 studies were included in the present study. We evaluated 1757 patients who were 41 to 72 years old. All selected studies comprised case-control studies and presented fair quality. Contrary to our hypothesis, HD patients showed impairment only in categorization skills in comparison with controls, particularly at confidence to complete categorization tasks. Regarding attention, episodic memory, working memory, information-processing speed, planning, decision-making, inhibitory control, mental flexibility, language, and visuospatial ability, HD patients did not show impairment when compared with controls. There is a paucity of studies on social cognition in HD patients, although they may show deficits. The impact of emotion in cognition is also understudied in HD patients. CONCLUSION Except for categorization skills, the cognitive performance in HD patients does not seem to be impaired when compared with that in controls. Further work is needed to explore social cognition and the impact of emotion in cognitive performance in HD patients.

Abstract
BACKGROUND The Obsessive-Compulsive Inventory-Children's Version (OCI-CV) was developed to assess obsessive-compulsive symptoms in youth. Recent changes in the Diagnostic and Statistical Manual (DSM-5) exclude hoarding from inclusion in the diagnosis of obsessive-compulsive disorder (OCD). Accordingly, the present study examined the reliability, validity, factorial structure, and diagnostic sensitivity of a revised version of the scale - the OCI-CV-R- that excludes items assessing hoarding. METHODS Participant were 1047 youth, including 489 meeting DSM criteria for primary OCD, 298 clinical controls, and 260 nonclinical controls, who completed the OCI-CV and measures of obsessive-compulsive symptom severity, depression, and anxiety at various treatment and research centers. RESULTS Findings support a five-factor structure (doubting/checking, obsessing, washing, ordering, and neutralizing), with a higher order factor. Factorial invariance was found for older (12-17 years) and younger (7-11 years) children. Internal consistency of the OCI-CV-R was acceptable, and discriminant and convergent validity were adequate and akin to that of its progenitor. Diagnostic sensitivity and specificity were found for a total score of 8 and higher. CONCLUSION It is recommended that the OCI-CV-R replace the former version, and that this measure serve as part of a comprehensive clinical assessment of youth with OCD. Recommendations for further research with ethnically and racially diverse samples, as well as the need to establish benchmark scores are discussed.

Abstract
This review covers recent findings in the genomics of obsessive-compulsive disorder (OCD), obsessive-compulsive symptoms, and related traits from a dimensional perspective. We focus on discoveries stemming from technical and methodological advances of the past five years and present a synthesis of human genomics research on OCD. On balance, reviewed studies demonstrate that OCD is a dimensional trait with a highly polygenic architecture and genetic correlations to multiple, often comorbid psychiatric phenotypes. We discuss the phenotypic and genetic findings of these studies in the context of the dimensional framework, relying on a continuous phenotype definition, and contrast these observations with discoveries based on a categorical diagnostic framework, relying on a dichotomous case/control definition. Finally, we highlight gaps in knowledge and new directions for OCD genetics research.

Abstract
OBJECTIVE Hoarding is common in obsessive-compulsive disorder (OCD), and OCD with hoarding may have poorer prognostic features than OCD without hoarding. The aim of this study was to investigate the relationship between multifaceted impulsivity and hoarding symptoms in individuals with OCD. This relationship is important to be able to understand the psychopathological mechanisms of hoarding symptoms in OCD patients. METHODS The study included 136 individuals with OCD classified as OCD with high hoarding symptoms (OCDwHH, n = 41) and OCD with low/none hoarding symptoms (OCDwLH, n = 95), together with 94 healthy control subjects. All the participants completed the Hoarding Rating Scale-Interview, Barratt Impulsiveness Scale-11, Yale-Brown Obsessions and Compulsions Scale, Hamilton Depression Rating Scale, and Hamilton Anxiety Rating Scale. RESULTS The OCDwHH group had more severe anxiety (p = 0.016) and attentional impulsivity (p = 0.002) than OCDwLH. Attentional impulsivity scores were positively correlated with hoarding symptom scores (p < 0.001). Both attentional and motor impulsivity scores were positively correlated with anxiety levels (p = 0.037, p = 0.045, respectively). In partial correlation analysis, motor impulsivity was positively correlated with the severity of hoarding symptoms controlling for anxiety severity (p = 0.045). In hierarchical linear regression analysis, only attentional impulsivity predicted the severity of hoarding symptoms independently of anxiety, severity of obsessive-compulsive symptoms and motor impulsivity (β = 0.268, Adjusted R2 = 0.114, p = 0.006). CONCLUSION Attentional impulsivity is associated with hoarding symptoms in OCD. Future studies that reveal this relationship may contribute to treatment modalities for the OCD patients with hoarding symptoms.

Abstract
Executive functions (EF) deficits are hypothesized to be a core contributor to hoarding symptoms. EF have been studied in adult hoarding populations, but studies in youth are lacking. The current study compared multiple EF subdomains between youth with obsessive-compulsive disorder (OCD) and youth with OCD and hoarding symptoms. Forty youth (8-18 years old) with a primary diagnosis of OCD were recruited. Participants were divided by hoarding severity on the Child Saving Inventory (CSI) into either the "hoarding group" (upper 33.3%) or the "low-hoarding group" (lower 66.7%). Groups were compared on EF tasks of cognitive flexibility, decision-making, and inhibitory control. Youth in the hoarding group exhibited significantly higher cognitive flexibility and lowered perseveration than the low-hoarding group. Hoarding and low-hoarding groups did not differ in any other EF subdomain. Hoarding symptoms in youth with OCD were not associated with deficits in EF subdomains; instead, youth who hoard exhibited higher cognitive flexibility compared to youth with low hoarding symptoms.

Abstract
BACKGROUND While the literature frequently highlighted an association between social anxiety disorder (SAD) and obsessive-compulsive disorder (OCD), few studies investigated the overlapping features of these conditions. The presented work evaluated the relationship between SAD and OCD spectrum in a clinical population and in healthy controls (HC). METHODS Fifty-six patients with OCD, 51 with SAD, 43 with major depressive disorder (MDD), and 59 HC (N = 209) were assessed using the Mini International Neuropsychiatric Interview, the Social Phobia Spectrum (SCI-SHY), and the Obsessive-Compulsive Spectrum (SCI-OBS). RESULTS SAD patients scored significantly higher than other groups on all SCI-SHY domains and total score; OCD patients scored significantly higher than HC. MDD patients scored significantly higher than HC on the SCI-SHY total, Behavioral inhibition, and Interpersonal sensitivity domains. OCD patients scored significantly higher than other groups on all SCI-OBS domains except Doubt, for which OCD and SAD scored equally high. SAD patients scored significantly higher than HC on the SCI-OBS total, Childhood/adolescence, Doubt, and Hypercontrol domains. MDD patients scored significantly higher than HC on the Hypercontrol domain. SCI-OBS and SCI-SHY were widely correlated among groups, although lower correlations were found among OCD patients. Stronger correlations were observed between SCI-SHY Interpersonal sensitivity and SCI-OBS Doubt, Obsessive-compulsive themes, and Hypercontrol; between SCI-SHY Specific anxieties/phobic features and SCI-OBS Obsessive-compulsive themes; and between SCI-SHY Behavioral inhibition and SCI-OBS Doubt, with slightly different patterns among groups. CONCLUSION OCD and SAD spectrums widely overlap in clinical samples and in the general population. Interpersonal sensitivity and obsessive doubts might represent a common cognitive core for these conditions.

BACKGROUND Hoarding, originally only considered a symptom of obsessive-compulsive disorder (OCD), is now categorized as a separate disorder in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). We studied candidate serotonergic genes and the distinctness of hoarding in children and adolescents and hypothesized that unique gene variants would be associated with hoarding alone. METHODS We examined obsessive-compulsive (OC) traits, including hoarding, in a total of 5,213 pediatric participants in the community. We genotyped candidate serotonin genes (5-HTTLPR polymorphism in SLC6A4 for 2,018 individuals and single nucleotide polymorphisms [SNPs] across genes SLC6A4, HTR2A, and HTR1B for 4,711 individuals). In a previous study conducted by our group in the same sample, we identified a significant association between 5-HTTLPR and hoarding in males. In this study, we examined hoarding more closely by testing the association between serotonin gene variants and hoarding traits with and without other accompanying OC traits. RESULTS The [LG +S] variant in 5-HTTLPR was significantly associated with hoarding alone in males (p-value of 0.009). There were no significant findings for 5-HTTLPR in females. There were no significant findings after correction for multiple comparisons using SNP array data, but top SNP findings suggested that variation downstream of HTR1B may be implicated in hoarding alone in females. CONCLUSIONS Our results suggest specific serotonin gene variants are associated with hoarding traits alone, differing between sexes. Top findings are in line with our former study, suggesting that individuals with hoarding alone were driving previous results. Our paper supports hoarding disorder's new designation.

Abstract
Hoarding, common in pediatric obsessive-compulsive disorder (OCD), has specific clinical correlates and is associated with poor prognosis. However, there are few studies of hoarding in pediatric OCD. This study estimates the occurrence of hoarding symptoms in a sample of children and adolescents with OCD, investigating possible differences in demographic and clinical variables between pediatric OCD with and without hoarding symptoms. Furthermore, the study investigates whether hoarding symptoms predict poorer treatment outcomes after cognitive behavioral therapy (CBT). The study sample comprised 269 children and adolescents with OCD, aged 7-17 years, from Denmark, Sweden, and Norway, who were all included in the Nordic long-term obsessive-compulsive disorder Treatment Study. All had an OCD diagnosis according to the DSM-IV and were treated with 14 weekly sessions of manualized, exposure-based CBT. Hoarding symptoms and OCD severity were assessed with the Children's Yale-Brown Obsessive-Compulsive Scale and group differences in treatment outcome were analyzed using linear mixed-effect modelling. Seventy-two patients (26.8%) had one or more symptoms of hoarding. Comorbid tic disorders (p = 0.005) and indecision (p = 0.024) were more prevalent among those with hoarding symptoms than those without hoarding symptoms. In addition, youth with hoarding symptoms had a different OCD symptom profile. Having symptoms of hoarding did not affect CBT outcome (p = 0.933). Results from the study suggest that CBT is equally effective for those with and without hoarding-related OCD.

Abstract
OBJECTIVE Although adult hoarding disorder is relatively common and often debilitating, few studies have examined the phenomenology of pediatric hoarding. We examined the clinical phenomenology and response to cognitive-behavioral therapy (CBT) treatment in youths with a diagnosis of obsessive-compulsive disorder (OCD) with and without hoarding symptoms. Age was tested as a moderator across analyses, given prior findings that the impact of hoarding symptoms may not become apparent until adolescence. METHOD Youths (N = 215; aged 7-17 years) with OCD pursuing evaluation and/or treatment at a university-based specialty clinic participated in the current study. Presence of hoarding symptoms was assessed as part of a larger battery. Data from a subset of youths (n = 134) who received CBT were included in treatment response analyses. RESULTS Youths with hoarding symptoms did not differ from those without hoarding symptoms with respect to overall OCD symptom severity and impairment. Youths with hoarding met criteria for more concurrent diagnoses, including greater rates of internalizing and both internalizing/externalizing, but not externalizing-only, disorders. Youths with and without hoarding symptoms did not significantly differ in rate of response to CBT. Age did not moderate any of these relationships, suggesting that the presence of hoarding symptoms was not associated with greater impairments across the clinical presentation of OCD or its response to treatment by age. CONCLUSION We found no evidence that hoarding is associated with greater OCD severity or poorer treatment response in affected youth. Theoretical and clinical implications of these findings, including future directions for research on testing developmental models of hoarding across the lifespan, are discussed.

Abstract
Hoarding disorder (HD) is a newly listed disease in the new category of Obsessive-Compulsive and Related Disorders in the DSM-5. Patients with HD find it difficult to discard possessions regardless of their actual value and to organize those things. As a result, the possessions overflow the living space and hinder living functions. Though the hoarding symptom had been regarded as a subtype of obsessive-compulsive disorder (OCD) to date, recent studies have revealed many differences in clinical characteristics, including onset, course, degree of insight, and treatment responses, between hoarding and other subtypes. Moreover, several neuroimaging studies have found specific changes of brain structure and function in OCD patients with hoarding symptoms compared to patients with non-hoarding OCD. Meanwhile, strategies for treatment of HD have not been standardized. At present, psychological treatment using cognitive behavioral therapy techniques has a certain effect. In this review, we outline the pathophysiology and treatment of HD.

Abstract
Hoarding disorder is present in 2-6% of the population and can have an immense impact on the lives of patients and their families. Before its inclusion the Diagnostic and Statistical Manual of Mental Disorders, 5th edition, pathological hoarding was often characterized as a symptom of obsessive-compulsive disorder, and several different diagnostic assessment methods were used to identify and characterize it. Although the age of onset of pathological hoarding is an important epidemiological measure, as clarifying the age of onset of hoarding symptoms may allow for early identification and implementation of evidence-based treatments before symptoms become clinically significant, the typical age of onset of hoarding is still uncertain. To that end, this study is a systematic review and meta-analysis of research published in English between the years 1900 and 2016 containing information on age of onset of hoarding symptoms. Twenty-five studies met inclusion criteria. The mean age of onset of hoarding symptoms across studies was 16.7 years old, with evidence of a bimodal distribution of onset. The authors conclude by discussing practice implications for early identification and treatment.

Abstract
Previous work has found gender differences in restricted and repetitive behaviors and interests (RRBI) for autism spectrum disorder (ASD). Compared to girls, affected boys have increased stereotyped and restricted behaviors; however much less is known about gender differences in other areas of RRBI. This study aims to identify whether specific RRBI (i.e., stereotyped, self-injurious, compulsive, insistence on sameness, ritualistic, and restricted), as measured by item-level data on the Repetitive Behavior Scale-Revised (RBS-R), can distinguish girls from boys with ASD. Participants included 615 individuals with ASD (507 boys; 82.4%), ages 3-18 years of age (M = 10.26, SD = 4.20), who agreed to share data with the National Database for Autism Research (NDAR). Multivariate analysis of variance and discriminant function analysis (DFA) were used to determine whether item-level RBS-R data could correctly classify cases by gender. DFA results suggest that RBS-R items significantly differentiate gender. Strongly differentiating RBS-R items had greater success in correctly classifying affected boys (67.90%) than girls (61.00%). Items that best-discriminated gender were heightened stereotyped behaviors and restricted interests items in boys and compulsive, sameness, restricted, and self-injurious behavior items in girls. This study is the first to find that girls with ASD may have increased compulsive, sameness, and restricted RRBI compared to boys. Additionally, findings support heightened self-injurious behaviors in affected girls. Future research should disentangle whether elevated rates of RRBI in girls are central to the presentation of ASD in girls or an epiphenomenon of the high rates of co-occurring disorders (e.g., anxiety) noted in girls. Autism Res 2019, 12: 274-283 © 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: This study is the first to examine a comprehensive measure of repetitive behavior in children with autism, with findings of increased compulsive, insistence on sameness, and self-injurious behavior characterizing girls and increased stereotyped and restricted behavior characterizing boys. Future research should determine whether these elevated behaviors in girls are directly part of the autism presentation in girls or symptoms of co-occurring psychopathology. It is important for autism diagnostic measures to best capture the types of repetitive behavior girls may demonstrate.

Abstract
The Children's Saving Inventory (CSI) was introduced in 2011 and is the first parent-rated questionnaire specifically designed to measure the severity of hoarding symptoms in youth. To date, however, no replication studies of the CSI have been published. Additionally, the total CSI score includes several items measuring acquisition, a behavioural dimension that has since been excluded from DSM-5's hoarding disorder criteria. Given these limitations, the primary goal of the present study was to test a modified, DSM-5-consistent, total score of the CSI. Because a confirmatory factor analysis did not support the 2011 four-factor model of the CSI, we reviewed the original CSI and excluded all acquisition items. An exploratory factor analysis yielded a strong three-factor solution (difficulty discarding, Clutter, and distress/impairment) with good reliability and validity for a 15-item version of the CSI. Overall, our results support the use of the 15-item CSI in youth with OCD.

Abstract
This article will review the evidence of various proposed factors that contribute to the onset and maintenance of hoarding disorder (HD). Data suggests that hoarding is a chronic condition that starts early in life and does not remit if left untreated. There is emerging evidence that a number of factors contribute to the expression of HD symptoms, including genetics, neurocognitive functioning, attachments to possessions, beliefs, avoidance, personality factors, and life events. The extent to which each etiological factor uniquely contributes to hoarding is still unknown. Other demographic factors, such as socioeconomic status, age, and gender, may impact hoarding severity. Research on the causes and characteristics of hoarding has recently started making progress into understanding this newly recognized disorder, yet we still have a ways to go in understanding the biological and environmental causes. This paper will synthesize available literature on the etiology of HD.

Heritability of hoarding symptoms across adolescence and young adulthood: A longitudinal twin study. PLoS One 2017; 12:e0179541.

Abstract
Background Twin studies of hoarding symptoms indicate low to moderate heritability during adolescence and considerably higher heritability in older samples, suggesting dynamic developmental etiological effects. The aim of the current study was to estimate the relative contribution of additive genetic and environmental effects to hoarding symptoms during adolescence and young adulthood and to estimate the sources of stability and change of hoarding symptoms during adolescence. Methods Univariate model-fitting was conducted in three cohorts of twins aged 15 (n = 7,905), 18 (n = 2,495) and 20–28 (n = 6,218). Longitudinal analyses were conducted in a subsample of twins for which data on hoarding symptoms was available at both age 15 and 18 (n = 1,701). Results Heritability estimates for hoarding symptoms at ages 15, 18 and 20–28 were 41% (95% confidence interval [CI]: 36–45%), 31% (95% CI: 22–39%) and 29% (95% CI: 24–34%) respectively. Quantitative sex-differences emerged in twins aged 15 at which point the heritability in boys was 33% (95% CI: 22–41%) and 17% (95% CI: 0–36%) in girls. Shared environmental effects played a negligible role across all samples with the exception of girls aged 15 where they accounted for a significant proportion of the variance (22%; 95% CI 6–36%). The longitudinal bivariate analyses revealed a significant phenotypic correlation of hoarding symptoms between ages 15 and 18 (0.40; 95% CI: 0.36–0.44) and a strong but imperfect genetic correlation (0.75; 95% CI: 0.57–0.94). The bivariate heritability was estimated to 65% (95% CI: 50–79%). Conclusions Hoarding symptoms are heritable from adolescence throughout young adulthood, although heritability appears to slightly decrease over time. Shared environmental effects contribute to hoarding symptoms only in girls at age 15. The stability of hoarding symptoms between ages 15 and 18 is largely explained by genetic factors, while non-shared environmental factors primarily have a time-specific effect. The findings indicate that dynamic developmental etiological effects may be operating across the life span.

Abstract
UNLABELLED Some studies have shown that children and adolescents with obsessive-compulsive disorder (OCD) and co-morbid tics differ from those without co-morbid tics in terms of several demographic and clinical characteristics. However, not all studies have confirmed these differences. This study examined children and adolescents with OCD and with possible or definite tic specifiers according to the DSM-5 in order to see whether they differ from patients without any tic symptoms regarding clinical presentation and outcome of cognitive behavioral therapy (CBT). The full sample included 269 patients (aged 7-17) with primary DSM-IV OCD who had participated in the Nordic Long-term Treatment Study (NordLOTS). Symptoms of tics were assessed using the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS-PL). One or more tic symptoms were found in 29.9% of participants. Those with OCD and co-morbid tic symptoms were more likely male, more likely to have onset of OCD at an earlier age, and differed in terms of OCD symptom presentation. More specifically, such participants also showed more symptoms of OCD-related impairment, externalization, autism spectrum disorder (ASD), social anxiety, and attention-deficit/hyperactivity disorder (ADHD). However, the two groups showed no difference in terms of OCD severity or outcome of CBT. Children and adolescents with OCD and co-morbid tic symptoms differ from those without tic symptoms in several aspects of clinical presentation, but not in their response to CBT. Our results underscore the effectiveness of CBT for tic-related OCD.

Abstract
The diagnostic conceptualization of hoarding has recently changed, and yet the application of these changes to hoarding in youth remains to be clarified. In this review we examine the literature on hoarding in youth. We discuss issues related to the assessment of pediatric hoarding, and the nature of hoarding in youth. We consider evidence for hoarding disorder as a distinct diagnosis in youth, and review the relationship between pediatric hoarding and other psychiatric disorders. Finally, we describe preliminary models of treatment for pediatric hoarding. We conclude that there is support for hoarding disorder as a distinct diagnosis in youth. However, more precise and developmentally appropriate assessment tools are needed to provide stronger evidence for this claim and to further our knowledge of prevalence and associated clinical characteristics. Although there is no evidence-based treatment for pediatric hoarding, preliminary evidence from case studies suggests that cognitive and behavioral methods may have promise.

The cost and impact of compulsivity: A research perspective. Eur Neuropsychopharmacol 2016; 26:800-9. [PMID: 27235690 DOI: 10.1016/j.euroneuro.2016.02.006] [Citation(s) in RCA: 49] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/24/2015] [Revised: 12/13/2015] [Accepted: 02/05/2016] [Indexed: 11/20/2022]
Abstract
Compulsivity is the defining feature of various psychiatric disorders including Obsessive Compulsive Related Disorders (OCRDs), and other compulsive, impulsive, and addictive disorders. These disorders are disabling, chronic conditions with an early onset and high rates of comorbidity, misdiagnoses, and delay in treatment onset. Disorders of compulsivity are responsible for considerable socioeconomic burden to society. We review the costs and impacts of compulsivity. In order to facilitate earlier diagnosis and targeted treatments, we examine the overlapping mechanisms that underlie compulsivity. We reconceptualize psychiatric disorders based on core features of compulsivity, highlight challenges in harmonizing research in children and adults, describe newer research methodologies, and point to future directions that can impact the costs and impact of disorders of compulsivity.

Clinical Correlates of Hoarding With and Without Comorbid Obsessive-Compulsive Symptoms in a Community Pediatric Sample. J Am Acad Child Adolesc Psychiatry 2016; 55:114-21.e2. [PMID: 26802778 DOI: 10.1016/j.jaac.2015.11.014] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/14/2015] [Revised: 11/06/2015] [Accepted: 11/20/2015] [Indexed: 11/22/2022]
Abstract
OBJECTIVE We assessed the prevalence and clinical correlates of hoarding, with and without obsessive-compulsive (OC) symptoms, in a community-based pediatric sample. METHOD We measured hoarding and OC symptoms using the Toronto Obsessive-Compulsive Scale (TOCS) in 16,718 youth aged 6 to 17 years in the community. We classified participants with high and low symptom counts for hoarding and OC into 4 groups: hoarding+OC; hoarding-only; OC-only; and control (no OC or hoarding symptoms). We compared these 4 groups on parent- or self-reported medical and psychiatric conditions, anxiety symptoms measured with the Child Behavior Checklist (CBCL), and attention-deficit/hyperactivity disorder (ADHD) symptoms measured with the Strengths and Weaknesses of Attention-Deficit/Hyperactivity Disorder Symptoms and Normal Behavior Scale (SWAN). RESULTS Almost 10% of participants were in the high hoarding group. Of these participants, 40% did not fall into the high OC group. The prevalence of reported psychiatric disorders (e.g., ADHD, autism spectrum disorder, obsessive-compulsive disorder) was greater in the hoarding (hoarding+OC and hoarding-only) and OC groups (hoarding+OC and OC-only) than in the nonhoarding (OC-only and control) and non-OC groups (hoarding-only and control), respectively. ADHD, specifically inattentive, symptoms were more common in the hoarding-only than in the OC-only group while anxiety symptoms were more common in the OC-only than in the hoarding-only group. CONCLUSION In a community pediatric sample, hoarding symptoms occurred in both the presence and absence of obsessive-compulsive symptoms. Hoarding symptoms alone had some unique clinical correlates, in particular, more inattentive ADHD symptoms and fewer anxiety symptoms. These findings suggest that hoarding is distinct from OC traits in youth.

Abstract
Hoarding is traditionally considered a disorder of adulthood but hoarding symptoms often begin in childhood and adolescence. However, there is very little published research into hoarding in youth. As described in this commentary, the study of hoarding in childhood and adolescence is important because hoarding symptoms: 1) often begin in childhood and adolescence; 2) often are chronic and persist into adulthood; and, 3) are associated with a number of negative outcomes and sequelae. Research into hoarding in youth could help identify individuals at risk for chronic and persistent hoarding disorder as well as determine interventions to change their trajectories. Improved understanding of hoarding in children and adolescents could in turn help minimize the negative effect of hoarding on the affected individuals, their families and society.
