Rett Syndrome Clinical Trial
Official title:
Characterization of Translatable Neurophysiological Biomarkers to Enhance Therapeutic Development in Rett Syndrome
The goal of this observational study is to identify candidate biomarkers in individuals with Rett Syndrome (RTT). The main questions it aims to answer are: - Do these biomarkers change during clinical changes in individuals with RTT? - Are biomarkers stable over time in clinically stable individuals? - Do these biomarkers correlate with severity of RTT? Participants will be asked to undergo an electroencephalogram (EEG) with measurements of Evoked Potentials (EP) to measure electrical activity in the brain. Researchers will compare findings in individuals with RTT to those in typically developing individuals to see if there are differences between the two groups.
The main goal of the project is to identify potential biomarkers that can become measures for intervention and other translational studies and, at the same time, provide insight into abnormal synaptic activity and pathogenesis of RTT. Therefore, the proposed assessments will be performed with females with RTT and age matched typically developing females. These electrophysiological assessments will be compared to established clinical outcome measures from previous work in the NIH funded Rett and Rett related disorders natural history study. The neurophysiological parameters for RTT will be correlated with each other and also to disease staging, overall clinical severity scores and through exploratory analyses with specific clinical features. The investigators will also be testing procedures to perform the recordings, electrode types and placement, and ways to reduce movement and artifact within the data to establish best practices. ;
