This paper describes the developmental profiles of eight infants with FXS from 9 to 24 months of age. Four meet diagnostic criteria for ASD at 24 months of age, and four do not. Trends in these case studies suggest that early social-communicative deficits differentiate infants with and without later ASD diagnoses in ways that are similar to later-born siblings of children with ASD. Repetitive behaviors and cognitive and adaptive impairments are present in all FXS infants throughout development, suggesting that these deficits reflect the general FXS phenotype and not ASD in FXS specifically.

Brief Report: Prevalence and Predictors of DSM-Specific and Distinct Anxiety in Cognitively Impaired Autistic Preschool Children / Connor M. KERNS ; Kimberly HILLS ; Abigail L. HOGAN-BROWN ; Sara MATHERLY ; Jane E. ROBERTS in Journal of Autism and Developmental Disorders, 55-5 (May 2025)

This study is the first to utilize an autism-specific anxiety diagnostic interview with 28 preschool cognitively impaired, autistic children and 18 neurotypical, age-matched controls. Results indicate that 64% of autistic children met criteria for DSM-specified or "other specified," herein referred to as "distinct," anxiety disorders; 32% met criteria for multiple anxiety disorders, with phobias occurring most often. Results indicate that anxiety is highly prevalent in cognitively-impaired, autistic preschool children, highlighting the need for developmentally-tailored assessment and treatment in early childhood.

Early behavioral and physiological markers of social anxiety in infants with fragile X syndrome / Conner J. BLACK in Journal of Neurodevelopmental Disorders, 13 (2021)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 13 (2021) Titre : Early behavioral and physiological markers of social anxiety in infants with fragile X syndrome Type de document : texte imprimé Auteurs : Conner J. BLACK, Auteur ; Abigail L. HOGAN, Auteur ; Kayla D. SMITH, Auteur ; Jane E. ROBERTS, Auteur Langues : Anglais (eng) Mots-clés : Anxiety  Attention  Autism Spectrum Disorder  Behavior  Biomarkers  Female  Fragile X Syndrome  Humans  Infant  Male  Fragile X syndrome  Physiology  Respiratory sinus arrhythmia  Social anxiety  Social behavioral inhibition Index. décimale : PER Périodiques Résumé : BACKGROUND: Social anxiety is highly prevalent in neurotypical children and children with fragile X syndrome (FXS). FXS is a genetic syndrome that is characterized by intellectual disability and an increased risk for autism spectrum disorder. If social anxiety is left untreated, negative outcomes are highly prevalent later in life. However, early detection of social anxiety is challenging as symptoms are often subtle or absent very early in life. Given the prevalence and impairment associated with childhood social anxiety, efforts have accelerated to identify risk markers of anxiety. A cluster of early features of anxiety have been identified including elevated behavioral inhibition, attentional biases, and physiological dysregulation that index early emerging markers of social anxiety. Infants with FXS provide a unique opportunity to study the earlier predictors of social anxiety. The current study utilized a multi-method approach to investigate early markers of social anxiety in 12-month-old infants with FXS. METHOD: Participants included 32 infants with FXS and 41 low-risk controls, all approximately 12 months old. Parent-reported social behavioral inhibition was recorded from the Infant Behavior Questionnaire (IBQ-R). Direct observations of behavioral inhibition and attention were measured during a stranger approach task with respiratory sinus arrhythmia collected simultaneously. RESULTS: Parent-reported social behavioral inhibition was not significantly different between groups. In contrast, direct observations suggested that infants with FXS displayed elevated behavioral inhibition, increased attention towards the stranger, and a blunted respiratory sinus arrhythmia response. CONCLUSIONS: Findings suggest that infants with FXS show both behavioral and physiological markers of social anxiety at 12 months old using a biobehavioral approach with multiple sources of input. Results highlight the importance of a multi-method approach to understanding the complex early emergent characteristics of anxiety in infants with FXS.

Early negative affect in males and females with fragile X syndrome: implications for anxiety and autism / Carla A. WALL in Journal of Neurodevelopmental Disorders, 11-1 (December 2019)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 11-1 (December 2019) . - 22 p.

Langues : Anglais (eng) Mots-clés : Anxiety  Autism spectrum disorder  Fragile X syndrome  Negative affect  Sex differences Index. décimale : PER Périodiques Résumé : BACKGROUND: Fragile X syndrome (FXS) is a genetic disorder that is highly comorbid with anxiety and autism spectrum disorder (ASD). Elevated negative affect in young children has been associated with increased risk for both anxiety and ASD; however, these relations remain poorly understood in FXS. METHODS: The present prospective longitudinal study examined the trajectory of negative affect from infancy through preschool in males and females with FXS and typical development and its relation to anxiety and ASD. RESULTS: Results indicate a complex association reflecting group, developmental, and sex effects. Specifically, the group with FXS displayed a trajectory of increasing negative affect across age that was distinct from the typical controls. This atypical trajectory of negative affect in FXS was driven by sex effects in that males showed lower negative affect during infancy followed by steep increases across the toddler and preschool years whereas the females displayed a flatter trajectory. Finally, elevated negative affect predicted anxiety symptoms in males, but not females, with no relationship to ASD in males or females with FXS. CONCLUSIONS: The current work addresses the importance of studying the development of psychopathology in a specific neurogenetic population. Temperamental negative affect was shown to be an important early marker for anxiety in young children with FXS, with subtle differences observed between males and females.

Emergence and rate of autism in fragile X syndrome across the first years of life / Jane E. ROBERTS in Development and Psychopathology, 32-4 (October 2020)

However, research on the emergence of ASD in disorders with a known genetic etiology, contextualized in a developmental framework, is currently lacking. Using a biobehavioral multimethod approach, we (a) determined the rate of ASD in N = 51 preschoolers with fragile X syndrome (FXS) using a clinical best estimate (CBE) procedure with differential diagnoses of comorbid psychiatric disorders and (b) investigated trajectories of ASD symptoms and physiological arousal across infancy as predictors of ASD in preschoolers with FXS. ASD was not diagnosed if intellectual ability or psychiatric disorders better accounted for the symptoms. Our results determined that 60.7% of preschoolers with FXS met the Diagnostic and Statistical Manual of Mental Disorders (fifth edition) (DSM-5) criteria for ASD using the CBE procedure. In addition, 92% of these preschoolers presented with developmental delay and 45.4% also met criteria for psychiatric disorders, either anxiety, ADHD, or both. ASD diagnoses in preschoolers with FXS were predicted by elevated scores on traditional ASD screeners in addition to elevated autonomic arousal and avoidant eye contact from infancy.
