Autism Spectrum Disorders and Low Mental Age: Diagnostic Stability and Developmental Outcomes in Early Childhood / Alexander J. HINNEBUSCH in Journal of Autism and Developmental Disorders, 47-12 (December 2017)

We examined diagnosis, symptom severity, and development in children with ASD-low MA (n = 25), autistic disorder (n = 111), and PDD-NOS (n = 82) at ages two and four. We predicted that some ASD-low MA children would demonstrate just intellectual impairment and not autism symptoms on follow-up, with social deficits at age two attributable to global delays. Instead, most ASD-low MA children (96%) had an ASD at follow-up, compared to children initially diagnosed with autistic disorder (86.5%) or PDD-NOS (73.2%). They showed the least developmental progress and highest symptom severity. Results support diagnosing ASDs in children functioning below a 12-month level.

Characteristics of toddlers with early versus later diagnosis of autism spectrum disorder / Lauren E. MILLER in Autism, 25-2 (February 2021)  

Public ISBD [article]  inAutism > 25-2 (February 2021) . - p.416-428 Titre : Characteristics of toddlers with early versus later diagnosis of autism spectrum disorder Type de document : texte imprimé Auteurs : Lauren E. MILLER, Auteur ; Yael G. DAI, Auteur ; Deborah A. FEIN, Auteur ; Diana L.

Data  reported in this manuscript did not incur any royalties. Lauren Miller and Yael Dai  declare that they have no conflicts of interest. Index. décimale : PER Périodiques Résumé : The emergence of autism symptoms in childhood is variable, with some children showing signs of autism spectrum disorder very early, and others not being identified until much later. Although most children in the United States are not diagnosed with autism spectrum disorder until preschool, at ages 3-4 years, symptoms can be reliably detected at 14 months. It is less certain how those toddlers diagnosed with autism spectrum disorder earlier versus later differ from each other clinically. This study revealed that young children diagnosed later in development, between ages 25 and 41 months, are more impaired on measures of cognitive, adaptive, and social functioning than their counterparts who are diagnosed with autism spectrum disorder earlier. All young children with autism spectrum disorder are impaired in communication to a similar degree, however. Universal autism screening at 18 months may identify toddlers with autism spectrum disorder when their symptoms are milder and more readily amenable to intervention. Repeated screening at 24 months is supported to detect those children missed by an earlier screening, who may be more severely affected. Caregivers should be encouraged to pursue diagnostic evaluation at an initial positive screening result to ensure timely diagnosis and treatment.

Comparison of parent report and direct assessment of child skills in toddlers / Lauren E. MILLER in Research in Autism Spectrum Disorders, 41-42 (September 2017)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 41-42 (September 2017) . - p.57-65 Titre : Comparison of parent report and direct assessment of child skills in toddlers Type de document : texte imprimé Auteurs : Lauren E.

FEIN, Auteur Article en page(s) : p.57-65 Langues : Anglais (eng) Mots-clés : Parent report  Direct assessment  Toddlers  Child ability  Autism spectrum disorder Index. décimale : PER Périodiques Résumé : There are unique challenges associated with measuring development in early childhood. Two primary sources of information are used: parent report and direct assessment. Each approach has strengths and weaknesses, particularly when used to identify and diagnose developmental delays. The present study aimed to evaluate consistency between parent report and direct assessment of child skills in toddlers with and without Autism Spectrum Disorder (ASD) across receptive language, expressive language, and fine motor domains. Method 109 children were evaluated at an average age of two years; data on child skills were collected via parent report and direct assessment. Children were classified into three groups (i.e., ASD, Other Developmental Disorder, or Typical Development) based on DSM-IV-TR diagnosis. Mixed design ANOVAs, with data source as a within subjects factor and diagnostic group as a between subjects factor, were used to assess agreement. Chi square tests of agreement were then used to examine correspondence at the item level. Results Results suggested that parent report of language and fine motor skills did not significantly differ from direct assessment, and this finding held across diagnostic groups. Item level analyses revealed that, in most cases of significant disagreement, parents reported a skill as present, but it was not seen on direct testing. Conclusions Results indicate that parents are generally reliable reporters of child language and fine motor abilities in toddlerhood, even when their children have developmental disorders such as ASD. However, the fullest picture may be obtained by using both parent report and direct assessment.

Diagnosing Autism Spectrum Disorder in Children with Low Mental Age / Lauren E. MILLER in Journal of Autism and Developmental Disorders, 49-3 (March 2019)

Autism Diagnostic Observation Schedule (ADOS) and Childhood Autism Rating Scale (CARS) were examined in 2-year-olds with ASD-low MA (n = 53), Global Developmental Delay (GDD; n = 175), and ASD-higher MA (n = 425). ADOS and CARS demonstrated similar agreement with clinical diagnosis, but ADOS over-classified ASD in low MA, whereas CARS both over- and under-classified. All ADOS items differentiated GDD from ASD. Elementary social behaviors (e.g., eye contact, social interest) were similar across ASD groups, although advanced skills (e.g., pointing, play) were more impaired in ASD-low MA. ASD-low MA, a severe presentation, may require a modified ADOS algorithm to account for developmental delays.

However, utility of rescreening at 24 months, after a negative 18-month screening, remains unknown. We identified cases of ASD detected at 24 months after a negative 18-month screening (i.e., Catch-24 group; n = 10) and compared them to toddlers detected by 18-month screening (i.e., Early Diagnosis group; n = 203). Repeated ASD-specific screening at 24 months detected children who were missed at their 18-month screening. Thus, our findings support repeated screening for ASD at both 18 and 24 months in order to maximize identification of toddlers with ASD and other neurodevelopmental disorders who require intervention.
