Atypical alpha oscillatory EEG dynamics in children with Angelman syndrome

The absence and lower frequency of alpha peaks in Angelman syndrome indicate that PAF is a developmentally sensitive marker of disrupted neural maturation in this population. Further research is needed to clarify how PAF emergence and shifts relate to longitudinal developmental trajectories and specific clinical phenotypes. Nonetheless, PAF shows promise as an objective, quantitative biomarker of neural circuit dynamics that can enhance clinical-trial endpoints by indexing underlying brain function. Future analyses will examine inter-individual variability in PAF among AS participants to uncover mechanistic pathways that may inform targeted therapeutic strategies.
