QEEG Spectral and Coherence Assessment of Autistic Children in Three Different Experimental Conditions / Calixto MACHADO in Journal of Autism and Developmental Disorders, 45-2 (February 2015)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 45-2 (February 2015) . - p.406-424 Titre : QEEG Spectral and Coherence Assessment of Autistic Children in Three Different Experimental Conditions Type de document : texte imprimé Auteurs : Calixto MACHADO, Auteur ; Mario ESTÉVEZ, Auteur ; Gerry LEISMAN, Auteur ; Robert MELILLO, Auteur ; Rafael RODRÍGUEZ, Auteur ; Phillip DEFINA, Auteur ; Adrián HERNÁNDEZ, Auteur ; Jesús PÉREZ-NELLAR, Auteur ; Rolando NARANJO, Auteur ; Mauricio CHINCHILLA, Auteur ; Nicolás GARÓFALO, Auteur ; José VARGAS, Auteur ; Carlos BELTRÁN, Auteur Article en page(s) : p.406-424 Langues : Anglais (eng) Mots-clés : Autism  Autism spectrum disorder  EEG  QEEG Index. décimale : PER Périodiques Résumé : We studied autistics by quantitative EEG spectral and coherence analysis during three experimental conditions: basal, watching a cartoon with audio (V–A), and with muted audio band (VwA). Significant reductions were found for the absolute power spectral density (PSD) in the central region for delta and theta, and in the posterior region for sigma and beta bands, lateralized to the right hemisphere. When comparing VwA versus the V–A in the midline regions, we found significant decrements of absolute PSD for delta, theta and alpha, and increments for the beta and gamma bands. In autistics, VwA versus V–A tended to show lower coherence values in the right hemisphere. An impairment of visual and auditory sensory integration in autistics might explain our results.

Biomarker development in Sturge-Weber syndrome / Siddharth S. GUPTA in Journal of Neurodevelopmental Disorders, 17 (2025)

Competing interests: A.M.C. is an inventor on  patents related to the R183Q GNAQ mutation in SWS and to the use of cannabidiol  for the treatment of SWS  no funding has been received by her from these patents.  The remaining authors have no conflicts of interest to disclose. Index. décimale : PER Périodiques Résumé : Sturge-Weber Syndrome (SWS) is a congenital neurovascular disorder caused by a somatic mosaic mutation in the R183Q GNAQ gene and characterized by capillary-venous malformations of the brain, skin, and eyes. Clinical manifestations include facial port-wine birthmark, glaucoma, seizures, headache or migraine, hemiparesis, stroke or stroke-like episodes, developmental delay, behavioral problems, and hormonal deficiencies. SWS requires careful monitoring, management, and early identification to improve outcome and prevent neurological deterioration. Over the last 25 years, biomarkers have been developed to improve early diagnosis and prognosis and allow for the monitoring of clinical status and treatment response. Importantly, advancements in biomarker research may enable presymptomatic treatment for infants with SWS. This review summarizes current, ongoing, and potential future SWS biomarker studies. These biomarkers, in combination with clinical data, offer a rich source of data for rare disease research leveraging machine learning in future research.
