A response to Arns et al. (2016) Type de document : Texte imprimé et/ou numérique Auteurs : Mark A. STEIN, Auteur ; Steven M. SNYDER, Auteur ; Thomas A. RUGINO, Auteur ; Mady HORNIG, Auteur Article en page(s) : p.770-771 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Neuropsychiatric EEG-Based ADHD Assessment Aid (NEBA) is an EEG-based device designed to aid in the diagnostic process for ADHD by identifying individuals less likely to have ADHD by virtue of a lower theta/beta ratio. In using NEBA as an example, the Arns et al. commentary misstates the purpose of NEBA, which is to widen the differential rather than to make the diagnosis. Arns et al. caution about missing an ADHD diagnosis, but fail to mention the impact of overdiagnosis. If we are to advance our knowledge of the etiology and pathophysiology of ADHD, as well as develop tailored treatments and ultimately improve outcomes for ADHD, then biomarkers and objective assessment aids such as NEBA are needed to improve and refine diagnostic accuracy beyond symptom description and clinical history.

Prenatal and Postnatal Epigenetic Programming: Implications for GI, Immune, and Neuronal Function in Autism / Mostafa WALY in Autism Research and Treatment, (May 2012)  

Public ISBD [article]  inAutism Research and Treatment > (May 2012) . - 13 p. Titre : Prenatal and Postnatal Epigenetic Programming: Implications for GI, Immune, and Neuronal Function in Autism Type de document : Texte imprimé et/ou numérique Auteurs : Mostafa WALY, Auteur ; Mady HORNIG, Auteur ; Malav TRIVEDI, Auteur ; Nathaniel HODGSON, Auteur ; Radhika KINI, Auteur ; Akio OHTA, Auteur ; Richard DETH, Auteur Année de publication : 2012 Article en page(s) : 13 p. Langues : Anglais (eng) Mots-clés : Maladie gastro-intestinale Index. décimale : PER Périodiques Résumé : Although autism is first and foremost a disorder of the central nervous system, comorbid dysfunction of the gastrointestinal (GI) and immune systems is common, suggesting that all three systems may be affected by common molecular mechanisms. Substantial systemic deficits in the antioxidant glutathione and its precursor, cysteine, have been documented in autism in association with oxidative stress and impaired methylation. DNA and histone methylation provide epigenetic regulation of gene expression during prenatal and postnatal development. Prenatal epigenetic programming (PrEP) can be affected by the maternal metabolic and nutritional environment, whereas postnatal epigenetic programming (PEP) importantly depends upon nutritional support provided through the GI tract. Cysteine absorption from the GI tract is a crucial determinant of antioxidant capacity, and systemic deficits of glutathione and cysteine in autism are likely to reflect impaired cysteine absorption. Excitatory amino acid transporter 3 (EAAT3) provides cysteine uptake for GI epithelial, neuronal, and immune cells, and its activity is decreased during oxidative stress. Based upon these observations, we propose that neurodevelopmental, GI, and immune aspects of autism each reflect manifestations of inadequate antioxidant capacity, secondary to impaired cysteine uptake by the GI tract. Genetic and environmental factors that adversely affect antioxidant capacity can disrupt PrEP and/or PEP, increasing vulnerability to autism.

The influence of parental concern on the utility of autism diagnostic instruments / Karoline Alexandra HAVDAHL in Autism Research, 10-10 (October 2017)

This study assessed diagnostic agreement of the ADOS-2 and ADI-R toddler algorithms in a more broadly based sample of 679 toddlers (age 35–47 months) from the Norwegian Mother and Child Cohort. We also examined whether parental concern about ASD influenced instrument performance, comparing toddlers identified based on parental ASD concern (n?=?48) and parent-reported signs of developmental problems (screening) without a specific concern about ASD (n?=?400). The ADOS cutoffs showed consistently well-balanced sensitivity and specificity. The ADI-R cutoffs demonstrated good specificity, but reduced sensitivity, missing 43% of toddlers whose parents were not specifically concerned about ASD. The ADI-R and ADOS dimensional scores agreed well with clinical diagnoses (area under the curve???0.85), contributing additively to their prediction. On the ADI-R, different cutoffs were needed according to presence or absence of parental ASD concern, in order to achieve comparable balance of sensitivity and specificity. These results highlight the importance of taking parental concern about ASD into account when interpreting scores from parental report-based instruments such as the ADI-R. While the ADOS cutoffs performed consistently well, the additive contributions of ADI-R and ADOS scores to the prediction of ASD diagnosis underscore the value of combining instruments based on parent accounts and clinician observation in evaluation of ASD.
