Salivary biomarkers of HPA axis and autonomic activity in adults with intellectual disability with and without stereotyped and self-injurious behavior disorders / F. J. SYMONS in Journal of Neurodevelopmental Disorders, 3-2 (June 2011)
[article]
Titre : Salivary biomarkers of HPA axis and autonomic activity in adults with intellectual disability with and without stereotyped and self-injurious behavior disorders Type de document : Texte imprimé et/ou numérique Auteurs : F. J. SYMONS, Auteur ; J. J. WOLFF, Auteur ; L. S. STONE, Auteur ; T. K. LIM, Auteur ; James W. BODFISH, Auteur Article en page(s) : p.144-51 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Salivary levels of biomarkers for the hypothalamic-pituitary-adrenal axis (HPA; cortisol) and sympatho-adreno-medullary system (SAM; alpha-amylase) were measured in 51 adults (57% male) with neurodevelopmental disorders associated with intellectual disability (i.e., mental retardation) and chronic self-injurious behavior (SIB) and compared with matched controls without SIB. Cortisol levels differed significantly (p < 0.01) between the SIB and control group (SIB > control). Within-group analyses showed significant differences (p < 0.05) in levels of salivary alpha-amylase between individuals with SIB and those with SIB meeting criteria for stereotyped movement disorder (SMD; SIB + SMD > SIB). Salivary alpha-amylase was significantly correlated with frequency of stereotypy among the SIB group (r = 0.36, p < 0.05). These preliminary findings warrant further exploration into the role of the SAM system in the pathophysiology of SIB and related repetitive behaviors among individuals with neurodevelopmental disorders associated with intellectual disability.

Titre : Subgrouping Autism Based on Symptom Severity Leads to Differences in the Degree of Convergence Between Core Feature Domains Type de document : Texte imprimé et/ou numérique Auteurs : A. WHITTEN, Auteur ; K. E. UNRUH, Auteur ; R. L. SHAFER, Auteur ; James W. BODFISH, Auteur Article en page(s) : p.1908-1919 Langues : Anglais (eng) Mots-clés : Autism Autism core features Phenotype Index. décimale : PER Périodiques Résumé : Existing models of autism spectrum disorder (ASD) disagree as to whether the core features should be conceptualized as convergent (related) or divergent (unrelated), and the few previous studies addressing this question have found conflicting results. We examined standardized parent ratings of symptoms from three domains (social, communication, repetitive behaviors) in large samples of typically developing children, children with ASD, and ASD subgroups. Our results suggest that the most evidence for divergence lies in typically developing children and lower severity ASD cases, while more evidence for convergence is found in a subset of cases with more severe impairment on any core feature. These results highlight the importance of subgrouping ASD given the degree of phenotypic heterogeneity present across the autism spectrum.

LEWIS, Auteur Article en page(s) : p.251-266 Langues : Anglais (eng) Mots-clés : autism spectrum disorders vestibulo-ocular reflex sensorimotor cerebellum dysrhythmia oculomotor Index. décimale : PER Périodiques Résumé : Sensorimotor processing alterations are a growing focus in the assessment and treatment of Autism Spectrum Disorders (ASD). The rotational vestibulo-ocular reflex (rVOR), which functions to maintain stable vision during head movements, is a sensorimotor system that may be useful in understanding such alterations and their underlying neurobiology. In this study, we assessed post-rotary nystagmus elicited by continuous whole body rotation among children with high-functioning ASD and typically developing children. Children with ASD exhibited increased rVOR gain, the ratio of eye velocity to head velocity, indicating a possible lack of cerebellar inhibitory input to brainstem vestibular nuclei in this population. The ASD group also showed less regular or periodic horizontal eye movements as indexed by greater variance accounted for by multiple higher frequency bandwidths as well as greater entropy scores compared to typically developing children. The decreased regularity or dysrhythmia in the temporal structure of nystagmus beats in children with ASD may be due to alterations in cerebellum and brainstem circuitry. These findings could potentially serve as a model to better understand the functional effects of differences in these brain structures in ASD.
