Differentiating early sensory profiles in toddlers at elevated likelihood of autism and association with later clinical outcome and diagnosis / Elena CAPELLI ; Chiara CANTIANI ; Carolina BERETTA ; Massimo MOLTENI ; Valentina RIVA in Autism, 28-7 (July 2024)  

Public ISBD [article]  inAutism > 28-7 (July 2024) . - p.1654-1666 Titre : Differentiating early sensory profiles in toddlers at elevated likelihood of autism and association with later clinical outcome and diagnosis Type de document : Texte imprimé et/ou numérique Auteurs : Elena CAPELLI, Auteur ; Chiara CANTIANI, Auteur ; Carolina BERETTA, Auteur ; Massimo MOLTENI, Auteur ; Valentina RIVA, Auteur Article en page(s) : p.1654-1666 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  development  infancy  sensory  siblings Index. décimale : PER Périodiques Résumé : Sensory features are included in the diagnostic criteria of autism spectrum disorder, and sensory responsiveness may produce "cascading effects" on later development. However, the relation between early sensory profiles and later skills has yet to be defined. This study aims to characterize sensory subgroups in 116 toddlers at elevated likelihood for autism spectrum disorder and test their association with later autistic traits and diagnosis. We used latent class analyses to assess individual differences across sensory patterns, grouping individuals with similar sensory profiles together. The final model was chosen based on a stepwise procedure, starting with a one-class solution, and then adds one class at a time. The Sensory Profile-2 Questionnaire measured clinical sensory features, and four sensory patterns were evaluated (seeking, avoiding, sensitivity, and registration). We investigated sensory subgroups concerning socio-communication skills and restricted/repetitive behaviors at 24?months and the clinical best-estimate diagnosis at 3?years. A three-class solution was favored, and toddlers can be characterized into three homogeneous sensory groups: low seeking, sensory balanced, and high sensitivity. The results showed that the high sensitivity group showed later socio-communicative difficulties and restricted/repetitive behaviors. Children in this class were those with the highest percentage of diagnosis at 3?years (57.9%). These findings provide new insights into the nature of sensory processing and may have implications for personalized support needs. Lay abstract Early sensory responsiveness may produce cascading effects on later development, but the relation between sensory profiles and autistic diagnosis remains unclear. In a longitudinal sample of toddlers at elevated likelihood for autism, we aimed to characterize sensory subgroups and their association with clinical outcomes later on. Three sensory subgroups were described and early sensory sensitivity plays a significant role in later development and diagnosis. This study supported the importance of examining different levels of sensory patterns to dissect the phenotypic heterogeneity in sensory processing. As sensory differences are associated with later developmental outcomes, these results may be critical when designing intervention needs and support for children at increased likelihood for neurodevelopmental disorders.

Enhanced motor noise in an autism subtype with poor motor skills / Veronica MANDELLI in Molecular Autism, 15 (2024)  

Public ISBD [article]  inMolecular Autism > 15 (2024) . - 36p. Titre : Enhanced motor noise in an autism subtype with poor motor skills Type de document : Texte imprimé et/ou numérique Auteurs : Veronica MANDELLI, Auteur ; Isotta LANDI, Auteur ; Silvia Busti CECCARELLI, Auteur ; Massimo MOLTENI, Auteur ; Maria NOBILE, Auteur ; Alessandro D'AUSILIO, Auteur ; Luciano FADIGA, Auteur ; Alessandro CRIPPA, Auteur ; Michael V. LOMBARDO, Auteur Article en page(s) : 36p. Langues : Anglais (eng) Mots-clés : Humans  Child  Male  Female  Adolescent  Motor Skills  Autistic Disorder/physiopathology  Child, Preschool  Biomechanical Phenomena  Clustering  Kinematics  Motor  Stratification  Subtypes  competing interests to declare. Index. décimale : PER Périodiques Résumé : BACKGROUND: Motor difficulties are common in many, but not all, autistic individuals. These difficulties can co-occur with other problems, such as delays in language, intellectual, and adaptive functioning. Biological mechanisms underpinning such difficulties are less well understood. Poor motor skills tend to be more common in individuals carrying highly penetrant rare genetic mutations. Such mechanisms may have downstream consequences of altering neurophysiological excitation-inhibition balance and lead to enhanced behavioral motor noise. METHODS: This study combined publicly available and in-house datasets of autistic (n = 156), typically-developing (TD, n = 149), and developmental coordination disorder (DCD, n = 23) children (age 3-16 years). Autism motor subtypes were identified based on patterns of motor abilities measured from the Movement Assessment Battery for Children 2nd edition. Stability-based relative clustering validation was used to identify autism motor subtypes and evaluate generalization accuracy in held-out data. Autism motor subtypes were tested for differences in motor noise, operationalized as the degree of dissimilarity between repeated motor kinematic trajectories recorded during a simple reach-to-drop task. RESULTS: Relatively 'high' (n = 87) versus 'low' (n = 69) autism motor subtypes could be detected and which generalize with 89% accuracy in held-out data. The relatively 'low' subtype was lower in general intellectual ability and older at age of independent walking, but did not differ in age at first words or autistic traits or symptomatology. Motor noise was considerably higher in the 'low' subtype compared to 'high' (Cohen's d = 0.77) or TD children (Cohen's d = 0.85), but similar between autism 'high' and TD children (Cohen's d = 0.08). Enhanced motor noise in the 'low' subtype was also most pronounced during the feedforward phase of reaching actions. LIMITATIONS: The sample size of this work is limited. Future work in larger samples along with independent replication is important. Motor noise was measured only on one specific motor task. Thus, a more comprehensive assessment of motor noise on many other motor tasks is needed. CONCLUSIONS: Autism can be split into at least two discrete motor subtypes that are characterized by differing levels of motor noise. This suggests that autism motor subtypes may be underpinned by different biological mechanisms.

Eye-Hand Coordination in Children with High Functioning Autism and Asperger’s Disorder Using a Gap-Overlap Paradigm / Alessandro CRIPPA in Journal of Autism and Developmental Disorders, 43-4 (April 2013)

The eye-hand correlation was measured by putting fixation latencies in relation with pointing and key pressing responses in visual detection tasks where a gap-overlap paradigm was used and compared to fixation latencies in absence of manual response. ASD patients showed less efficient eye-hand coordination, which was particularly evident when pointing towards a target was being fixated. The data of normally developing participants confirmed that manual gap effects are more likely for more complex hand movements. An important discrepancy was discovered in participants with ASD: beside normal eye gap effects, they showed no concurrent hand gap effects when pointing to targets. This result has been interpreted as a further sign of inefficient eye-hand coordination in this patient population.

To the end to provide further information on the PEP-R’s psychometric properties, a large sample (N = 137) of children presenting Autistic Disorder symptoms under the age of 12 years, including low-functioning individuals, was examined. Results yielded data of interest especially in terms of: Cronbach’s alpha, interrater reliability, and validation with the Vineland Adaptive Behavior Scales. These findings help complete the instrument’s statistical description and augment its usefulness, not only in designing treatment programs for these individuals, but also as an instrument for verifying the efficacy of intervention.

Further evidence of complex motor dysfunction in drug naïve children with autism using automatic motion analysis of gait / Maria NOBILE in Autism, 15-3 (May 2011)  

Public ISBD [article]  inAutism > 15-3 (May 2011) . - p.263-283 Titre : Further evidence of complex motor dysfunction in drug naïve children with autism using automatic motion analysis of gait Type de document : Texte imprimé et/ou numérique Auteurs : Maria NOBILE, Auteur ; Paolo PEREGO, Auteur ; Luigi PICCININI, Auteur ; Elisa MANI, Auteur ; Agnese ROSSI, Auteur ; Monica BELLINA, Auteur ; Massimo MOLTENI, Auteur Année de publication : 2011 Article en page(s) : p.263-283 Langues : Anglais (eng) Mots-clés : autism  gait analysis  jerk  locomotion system  motor dysfunction Index. décimale : PER Périodiques Résumé : In order to increase the knowledge of locomotor disturbances in children with autism, and of the mechanism underlying them, the objective of this exploratory study was to reliably and quantitatively evaluate linear gait parameters (spatio-temporal and kinematic parameters), upper body kinematic parameters, walk orientation and smoothness using an automatic motion analyser (ELITE systems) in drug naïve children with Autistic Disorder (AD) and healthy controls. The children with AD showed a stiffer gait in which the usual fluidity of walking was lost, trunk postural abnormalities, highly significant difficulties to maintain a straight line and a marked loss of smoothness (increase of jerk index), compared to the healthy controls. As a whole, these data suggest a complex motor dysfunction involving both the cortical and the subcortical area or, maybe, a possible deficit in the integration of sensory-motor information within motor networks (i.e., anomalous connections within the fronto-cerebello-thalamo-frontal network). Although the underlying neural structures involved remain to be better defined, these data may contribute to highlighting the central role of motor impairment in autism and suggest the usefulness of taking into account motor difficulties when developing new diagnostic and rehabilitation programs.
