EEG Biomarkers of Language in Angelman Syndrome


The goal of this study is to establish biomarkers of language function in Angelman syndrome. Language is a likely target for both behavioral and pharmaceutical treatment, as it represents a core deficit in Angelman syndrome and is a major area of unmet need in this community.

Given the wide-ranging challenges that individuals with Angelman syndrome experience, it is difficult to obtain accurate and meaningful results when using traditional behavioral assessments, such as the Vineland and Bayley scales. For this reason, developing quantitative, objective measures that do not rely on the individual’s ability to understand verbal instructions or complete standardized tasks will greatly improve traditional language assessments.

This study will measure brain responses to different aspects of language processing in children with Angelman syndrome and will compare these biomarkers to those measured in typically developing children and children with autism spectrum disorder. In addition to establishing biomarkers of language processing, our findings may help us detect previously unrecognized language abilities in individuals with Angelman syndrome, providing information about the true communicative capacity in this population and increasing their access to appropriate interventions.
