Neurobehavioral outcomes of neonatal asymptomatic congenital cytomegalovirus infection at 12-months. J Neurodev Disord 2024; 16:19. [PMID: 38637762 PMCID: PMC11025208 DOI: 10.1186/s11689-024-09533-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Accepted: 04/02/2024] [Indexed: 04/20/2024] Open
Abstract
BACKGROUND Congenital cytomegalovirus (cCMV) is the most common congenital viral infection in the United States. Symptomatic infections can cause severe hearing loss and neurological disability, although ~ 90% of cCMV infections are asymptomatic at birth. Despite its prevalence, the long-term neurobehavioral risks of asymptomatic cCMV infections are not fully understood. The objective of this work was to evaluate for potential long-term neurobehavioral sequelae in infants with asymptomatic cCMV. METHODS Infants with cCMV were identified from a universal newborn cCMV screening study in a metropolitan area in the midwestern United States. Asymptomatic infants with cCMV were enrolled in a longitudinal neurodevelopmental study (N = 29). Age- and sex-matched healthy control infants (N = 193) were identified from the Baby Connectome Project (BCP), a longitudinal study of brain and behavioral development. The BCP sample supplemented an additional group of healthy control infants (N = 30), recruited from the same participant registry as the BCP specifically for comparison with infants with asymptomatic cCMV. Neurobehavioral assessments and parent questionnaires, including the Mullen Scales of Early Learning, the Repetitive Behavior Scales for Early Childhood (RBS-EC), and the Infant Toddler Social Emotional Assessment (ITSEA) were administered at 12 months of age. Neurobehavioral scores were compared between infants with asymptomatic cCMV and all identified healthy control infants. RESULTS Infants with asymptomatic cCMV performed equivalently compared to healthy control infants on the neurobehavioral measures tested at 12 months of age. CONCLUSIONS These results indicate that at 12 months of age, infants with asymptomatic cCMV are not statistically different from controls in a number of neurobehavioral domains. Although follow-up is ongoing, these observations provide reassurance about neurobehavioral outcomes for infants with asymptomatic cCMV and inform the ongoing discussion around universal screening. Additional follow-up will be necessary to understand the longer-term outcomes of these children.

Alarifi S, Denne L, Hastings RP. Challenging behaviour and its correlates in preschool-aged children with an intellectual disability in Saudi Arabia. JOURNAL OF INTELLECTUAL DISABILITY RESEARCH : JIDR 2024; 68:264-276.

Abstract
BACKGROUND Young children with an intellectual disability have a higher risk of developing challenging behaviour (CB). Early identification of risk factors for CB allows for earlier intervention. The aim of the current study was to assess the prevalence and correlates of CB in preschool-aged children with an intellectual disability in Riyadh (Saudi Arabia). METHODS One hundred twenty parents of preschool-aged (3-6 years old) children who had been diagnosed (DSM-5 criteria) with an intellectual disability completed an online cross-sectional survey that included demographic, CB and child adaptive skills measures. The relationship between CB and 15 potential correlates (e.g. gender and degree of disability) was examined using independent samples t-tests and chi-squared tests. RESULTS Most preschool-aged (3-6 years old) children with an intellectual disability exhibited CB (78.8%, 95% CI [70.3, 85.8]), with a 63.2% prevalence rate for self-injurious behaviours (95% C [53.8, 72.0]), a 57.6% rate for aggressive destructive behaviours (95% CI [48.2, 66.7]) and a 25% rate for stereotypy (95% CI [17.7, 34.0]). The likelihood of a child engaging in self-injurious and stereotyped behaviours was higher in those with autism and intellectual disability. Children with Down syndrome displayed fewer stereotyped behaviours. Low adaptive skill levels were associated with increased overall CB, self-injurious and stereotyped behaviours. CONCLUSIONS The identified correlates of CB in this population and cultural context align with the international evidence base. Findings have implications for the importance of early systematic screening of CB in preschool-aged children in Saudi Arabia and other similar contexts. Preventative measures are suggested for preschool-aged children with an intellectual disability who are more likely to demonstrate CB, such as those with autism and poor adaptive behaviours.

Abstract
PURPOSE OF REVIEW Migraine is a common condition affecting an estimated billion people across the world. The incidence in individuals with neurodevelopmental disorders or intellectual disabilities like those seen in severe autism spectrum disorder (ASD) is unknown. This is likely due to the limited capacity to communicate the specifics of pain. The expression of pain with maladaptive behaviors, such as self-injurious behavior (SIB), has been described and can alert the clinician to the presence of untreated pain. This review article serves to educate the reader about clinical and treatment considerations when managing headaches in individuals with severe or non-verbal neurodevelopmental disorders given their communication challenges. It will include some clinical experiences and the gaps in our current knowledge. RECENT FINDINGS A comprehensive literature review was conducted using scientific databases, including PubMed, Medline, and Google Scholar. Only 1 article addressed the consideration for headaches in this population. The search was conducted using a combination of the following keywords: headache, intellectual disabilities, autism, pain, and behavior. Headache pain is likely underestimated and represents a disservice to this population of people. The consideration for headache pain should be explored when maladaptive behaviors are otherwise unexplainable. Further studies are needed in the area.

Abstract
Existing research suggests that self-injurious behavior (SIB) is a relatively common interfering behavior that can occur across the lifespan of individuals with autism spectrum disorder (ASD). We previously reported that SIB or proto-injurious SIB at 12 months was related to increased risk of SIB at 24 months among a preschool sample of children with a high familial likelihood for ASD (Dimian et al., 2017). In the present study, we extend these findings, examine SIB occurrence, and associated potential risk factors at 36 months. The present sample included 149 infants with an older sibling with ASD (65.8% male) who completed assessments at ages 12, 24, and 36 months. Descriptive analyses and binary logistic regression models were utilized. SIB was more prevalent among those children who received a diagnosis of ASD. Logistic regression indicated that presence of SIB, stereotypy, hyper- and hypo- sensory responsivity, and lower intellectual functioning at age 12 months significantly predicted the occurrence of SIB at 36 months. These findings have implications for understanding developmental processes culminating in persistent SIB and may inform prevention programming.

Abstract
While the core symptoms of autism spectrum disorder include repetitive thoughts and repetitive behaviors, repetitive phenomena also occur in many other psychiatric disorders. Types of repetitive thoughts include preoccupations, ruminations, obsessions, overvalued ideas, and delusions. Types of repetitive behaviors include tics, stereotypies, compulsions, extrapyramidal symptoms, and automatisms. We provide a description of how to recognize and classify different types of repetitive thoughts and behaviors in autism spectrum disorder, providing clarity on which phenomena should be considered a core feature of autism spectrum disorder and which phenomena are indicative of a comorbid psychiatric disorder. Clinical features that can be used to differentiate types of repetitive thoughts include whether they are distressing and the degree of insight the individual has, while repetitive behaviors can be classified based on whether they are voluntary, goal-directed/purposeful, and rhythmic. We present the psychiatric differential diagnosis of repetitive phenomena within the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) framework. Careful clinical consideration of these transdiagnostic features of repetitive thoughts and behaviors can improve diagnostic accuracy and treatment outcomes, and influence future research.

Abstract
OBJECTIVES To examine the frequency of repetitive behaviors among children with autism spectrum disorder (ASD) and compare it to age-matched developmentally delayed (DD) and typically developing children (TD). METHODS Twenty-five children (3-8 y) with a diagnosis of ASD were compared to two age-matched control groups namely the DD and TD groups. The Repetitive Behaviors Scale-Revised (RBS-R) was administered to the parents to assess the frequency, severity, and impairment associated with restricted, repetitive behaviors, and interests (RRBIs) displayed. The study was cleared by the institute ethics committee. RESULTS The three groups were well matched on age and sex distribution and comparisons on the RBS-R showed that the ASD group had a significantly higher total score (F = 51.52, p = 0.0001) and number of items endorsed on the scale (F = 37.91, p = 0.0001). Stepwise multiple regression analysis revealed that 35.8% of the variance in the total RRBI score of the ASD children was explained by the age and severity of autism (F = 6.12. p = .008). Older children with severe ASD features had significantly higher total RRBI scores. CONCLUSIONS RRBIs are not just specific to autism and should not be used in isolation to identify children with autism. Gaining a complete understanding of the complexity and variability of the restricted interests would help in improving the diagnostic procedures and in the development of a comprehensive therapeutic plan.

Abstract
The rising prevalence of autism spectrum disorder (ASD) has increased awareness of the need for early diagnosis and intervention; however, not all children are diagnosed at preschool age. In the literature, findings regarding factors that may play a role in later diagnosis are inconsistent. Presence or absence of intellectual disability is a possible factor. This study aimed to identify factors associated with later diagnosis of ASD among children grouped according to low and high cognitive levels. Data of children who were previously diagnosed with ASD between 2002 and 2016 at a national autism center were analyzed. Better cognitive ability, having more siblings, and previous diagnosis of attention-deficit/hyperactivity disorder were predictors of later diagnosis among the entire cohort. Children exhibiting lower cognitive levels (LC-ASD; DQ/IQ < 70; n = 209) were diagnosed much earlier. Among this group, later ASD diagnosis was predicted by poorer adaptive behavior, more severe restricted and repetitive behaviors, and previous diagnosis of epilepsy. In the higher cognitive level group (HC-ASD; DQ/IQ ≥ 70; n = 321), familial variables and more severe social impairments were predictors of later ASD diagnosis. Clinicians should be aware of variables that may affect ASD diagnostic age among children with varying cognitive abilities.

Abstract
Increasing numbers of children with known genetic conditions and/or intellectual disability are referred for evaluation of autism spectrum disorder (ASD), highlighting the need to refine autism symptom measures to facilitate differential diagnoses in children with cognitive and language impairments. Previous studies have reported decreased specificity of ASD screening and diagnostic measures in children with intellectual disability. However, little is known about how cognitive and language abilities impact the measurement of specific ASD symptoms in this group. We aggregated a large sample of young children (N = 1196; aged 31-119 months) to examine measurement invariance of ASD symptoms among minimally verbal children within the context of the Autism Diagnostic Observation Schedule (ADOS) Module 1. Using confirmatory factor analysis (CFA) and moderated non-linear factor analysis (MNLFA), we examined how discrete behaviors were differentially associated with the latent symptom domains of social communication impairments (SCI) and restricted and repetitive behaviors (RRB) across spoken language levels and non-verbal mental age groupings. While the two-factor structure of SCI and RRB held consistently across language and cognitive levels, only partial invariance was observed for both ASD symptom domains of SCI and RRB. Specifically, four out of the 15 SCI items and one out of the three RRB items examined showed differential item functioning between children with "Few to No Words" and those with "Some Words"; and one SCI item and one RRB item showed differential item functioning across non-verbal mental age groups. Moreover, even after adjusting for the differential item functioning to reduce measurement bias across groups, there were still differences in ASD symptom domain scores across spoken language levels. These findings further underscore the influence of spoken language level on measurement of ASD symptoms and the importance of measuring ASD symptoms within refined spoken language levels, even among those with minimal verbal abilities.

Abstract
The assessment of challenging behavior exhibited by people with intellectual and developmental disabilities is essential for the planning of prevention and intervention programs. This review aimed to identify and analyze the standardized instruments that exclusively focus on the assessment of challenging behavior. We identified and organized 141 articles into four categories: original instrument studies, validation studies, relational studies, and intervention studies. The results identified 24 instruments that generally show high-quality psychometric properties and other utilities beyond the observation of the presence of challenging behavior and diagnostic categorization. Age, level of adaptive behavior, disability, presence of autism spectrum disorder, and medication are some of the variables that were found to be possibly related to the occurrence of challenging behavior. Additionally, the results suggest that interventions focused on supporting positive behavior or providing training on behavior to professionals and caregivers significantly reduced the occurrence of these behaviors. Instruments that help us to understand and measure the challenging behavior exhibited by people with intellectual and developmental disabilities are essential for the design of effective evaluation and intervention protocols.

Abstract
Self-injurious behavior (SIB) by individuals with intellectual and developmental disabilities including autism (I/DD) is among the most clinically disturbing, socially costly, and scientifically challenging behavior disorders. Forty years of clinical research has produced a knowledge base supporting idiographic behavioral assessment and treatment approaches. Despite the treatment progress, from a public health and population perspective, we argue it is less clear that we have reduced the disorder's burden. The developmental course of the disorder is mostly unknown and empirically informed population-level models of risk are absent. In this review, we systematically examined the published scientific literature specific to risk for SIB in the I/DD population. We reviewed study methodology in detail intentionally informed by an epidemiological perspective with a set of questions intended to test the quality of the inferences about risk. Results are discussed in terms of conceptual, methodological, and translational issues with respect to what needs to be done to create credible and useful clinical models for SIB risk in the I/DD population.

Abstract
Non-suicidal self-injury (NSSI) is a type of behavioral pathology seen not only in a variety of clinical conditions but also among non-clinical populations, particularly adolescents and young adults. With the exception of rare genetic conditions that give rise to self-harming behaviors, the etiology of NSSI and the events that trigger specific episodes of this behavior remain poorly understood. This review presents the features of an important, extensively studied animal model of NSSI, namely spontaneously occurring self-injurious behavior (SIB) in rhesus macaque monkeys. We compare and contrast rhesus monkey SIB with NSSI with respect to form, prevalence rates, environmental and biological risk factors, behavioral correlates, proposed functions, and treatment modalities. Many parallels between rhesus monkey SIB and NSSI are demonstrated, which supports the validity of this animal model across several domains. Determining the etiology of spontaneously occurring SIB in monkeys, its underlying biological mechanisms, and which pharmacological agents are most effective for treating the disorder may aid in identifying potential risk factors for the occurrence of NSSI in humans and developing medications for severe cases that are resistant to conventional psychotherapeutic approaches.

Abstract
BACKGROUND Restricted and repetitive behaviors (RRBs) are core features of autism spectrum disorder (ASD) and one of the earliest behavioral signs of ASD. However, RRBs are also present in typically developing (TD) infants, toddlers, and preschool-aged children. Past work suggests that examining change in these behaviors over time is essential to distinguish between normative manifestations of these behaviors and behaviors that denote risk for a neurodevelopmental disorder. One challenge in examining changes in these behaviors over time is that most measures of RRBs have not established longitudinal measurement invariance. The aims of this study were to (1) establish measurement invariance in the Repetitive Behavior Scales for Early Childhood (RBS-EC), a parent-report questionnaire of RRBs, and (2) model developmental change in RRBs from 8 to 36 months. METHODS We collected RBS-EC responses from parents of TD infants (n = 180) from 8 to 36 months (n = 606 responses, with participants contributing an average of 3-time points). We leverage a novel methodological approach to measurement invariance testing (Bauer, Psychological Models, 22(3), 507-526, 2017), moderated nonlinear factor analysis (MNLFA), to determine whether the RBS-EC was invariant across age and sex. We then generated adjusted factor score estimates for each subscale of the RBS-EC (repetitive motor, self-directed, and higher-order behaviors), and used linear mixed effects models to estimate between- and within-person changes in the RBS-EC over time. RESULTS The RBS-EC showed some non-invariance as a function of age. We were able to adjust for this non-invariance in order to more accurately model changes in the RBS-EC over time. Repetitive motor and self-directed behaviors showed a linear decline from 8 to 36 months, while higher-order behaviors showed a quadratic trajectory such that they began to decline later in development at around 18 months. Using adjusted factor scores as opposed to unadjusted raw mean scores provided a number of benefits, including increased within-person variability and precision. CONCLUSIONS The RBS-EC is sensitive enough to measure the presence of RRBs in a TD sample, as well as their decline with age. Using factor score estimates of each subscale adjusted for non-invariance allowed us to more precisely estimate change in these behaviors over time.

JOURNAL OF INTELLECTUAL DISABILITY RESEARCH : JIDR 2020; 64:673-680. [PMID: 32643272 PMCID: PMC8212423 DOI: 10.1111/jir.12758] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/10/2020] [Revised: 06/03/2020] [Accepted: 06/04/2020] [Indexed: 05/12/2023]
Abstract
BACKGROUND The present study presents post hoc analyses of specific topographies of self-injurious behaviour (SIB) exhibited by young children with developmental delay (DD) and children with typical development (TD). We conducted these analyses to better understand similarities and differences between the groups from a developmental perspective. No previous study has compared the prevalence, severity and co-occurrence of specific topographies of SIB in young children. METHOD The participants were parents of two groups of children one with DD (n = 49, mean age = 37.5 months) and one with TD (n = 49, mean age = 36.6 months). Individual items of the SIB subscale from the Repetitive Behaviour Scale-Revised were used in the analyses. RESULTS Seven of the eight Repetitive Behaviour Scale-Revised SIB categories were reported for both groups. Children in the DD group were significantly more likely to engage in Hits Self against Surface or Object, Hits Self with Body Part, Inserts Finger or Object, Skin Picking and Bites Self. Parental ratings of severity were also significantly greater for the DD group for these five topographies. The DD group engaged in a significantly greater number of SIB topographies than the children in the TD group. Children in the TD group were more likely to exhibit a single SIB topography while the DD group were more likely to engage in two or more topographies. Topographies involving self-hitting were not only more frequent among the children in the DD group but also more likely to be rated as moderate or severe in nature. CONCLUSIONS Compared with the TD group, the topographies of SIB exhibited by the DD group were more prevalent, more severe and co-occurred with greater frequency. Inclusion of a group of children with TD provided an important comparative context for the occurrence of SIB in children with DD.

Abstract
Repetitive sensory motor behaviors are a direct target for clinical treatment and a potential treatment endpoint for individuals with intellectual or developmental disabilities. By removing the burden associated with video annotation or direct observation, automated detection of stereotypy would allow for longer term monitoring in ecologic settings. We report automated detection of common stereotypical motor movements using commercially available accelerometers affixed to the body and a generalizable detection algorithm. The method achieved a sensitivity of 80% for body rocking and 93% for hand flapping without individualized algorithm training or foreknowledge of subject's specific movements. This approach is well-suited for implementation in a continuous monitoring system outside of a clinical setting.

Abstract
Head banging is a commonly observed movement disorder which is typically self-limited. Complications secondary to this behavior are rare. In this report, the authors present the case of a 15-year-old patient who was treated for a forehead mass which developed secondary to chronic head banging. Surgical excision was performed for treatment of the lesion. Results from surgical pathology were notable for fibrosis consistent with history of chronic head banging. Preoperative magnetic resonance imaging and physical examination were also consistent with this diagnosis. This is a rare clinical entity that should be considered in patients presenting with a forehead mass and a history of head banging.

Abstract
Prevalence of self-injurious behavior (SIB) is as high as 50% among children with autism spectrum disorder (ASD). Identification of risk factors for the development of SIB is critical to early intervention and prevention. However, there is little empirical research utilizing a prospective design to identify early risk factors for SIB. The purpose of this study was to evaluate behavioral characteristics predicting SIB at age 2 years among 235 infants at high familial risk for ASD. Logistic regression results indicated that presence of SIB or proto-SIB and lower developmental functioning at age 12 months significantly predicted SIB at 24 months. A pattern of persistent SIB over this period was associated with a diagnosis of autism and poorer cognitive and adaptive outcomes.

Abstract
PURPOSE OF REVIEW This review summarises the recent trends in research in the field of self-injurious behaviour in people with intellectual disability and autism spectrum disorder. RECENT FINDINGS New data on incidence, persistence and severity add to studies of prevalence to indicate the large scale of the clinical need. A number of person characteristics have been repeatedly identified in prevalence and cohort studies that: can be considered as risk markers (e.g. stereotyped behaviour, autism spectrum disorder) and indicate possible causal mechanisms (e.g. sleep disorder, anxiety). Studies have started to integrate traditional operant learning paradigms with known person characteristics and reviews and meta-analyses of applied behaviour analytic procedures can now inform practice. SUMMARY Despite these positive developments interventions and appropriate support falls far short of the required need. Expansions in applied research are warranted to develop and evaluate innovative service delivery models that can translate knowledge of risk markers and operant learning paradigms into widespread, low cost routine clinical practice. Alongside this, further pure research is needed to elucidate the direction of causality of implicated risk factors, in order to understand and intervene more effectively in self-injury.

Abstract
Most neurodevelopmental disorders are defined by their clinical symptoms and many disorders share common features. Recently there has been an increase in the number of children diagnosed with autism spectrum disorder, although concerns have been raised about the accuracy of the reported prevalence rates. This article reviews the essential features of autism spectrum disorder and describes other conditions that may include similar symptoms that may be misdiagnosed as autism spectrum disorder (primary communication disorders, anxiety disorders, attachment disorders, intellectual disability, vision and hearing impairment, and normal variations). An approach to differential diagnosis is discussed with particular attention to evaluation of young children.

Abstract
Background Restricted and repetitive behaviors are characteristic phenotypic features of many neurodevelopmental, psychiatric, and neurological conditions. During early childhood, such behaviors are considered normative. More research is needed to delineate the dimensions of restricted and repetitive behavior across typical and atypical development during this period. Methods We developed the 34-item parent-rated Repetitive Behavior Scale for Early Childhood (RBS-EC) to capture quantitative, dimensional features across a broad range of behaviors contributing to this domain. We evaluated its psychometric properties and factor structure in a community sample of 914 toddlers. Results The RBS-EC showed excellent overall internal consistency (α = 0.90), strong test-retest reliability (ICC = 0.87 for topographies and 0.90 for frequency) and evidence of convergent and discriminative validity. Using a split-half approach to factor analysis, we identified that a three- or four-factor structure best fit the data and confirmatory factor analysis indicated acceptable fit for both models. The empirically derived four-factor model was consistent with our conceptual model and included repetitive motor, restricted interests and behavior, ritual and routine, and self-directed behavior. Conclusions This initial study indicates that the RBS-EC is a reliable and valid instrument for characterizing quantitative, dimensional aspects of restricted and repetitive behaviors in young children.
