Electrical Responses in Brain to Stimuli May Be Marker of Rett Severity

People with Rett syndrome have significantly weaker electrical responses in the brain to visual and auditory stimuli than do their healthy peers, according to an analysis of patients in a natural history study in the U.S. The strength of these responses was also associated with both age and disease severity. These findings suggest that brain electrical signals in response to stimuli, known as evoked potentials (EPs), might be a non-invasive biomarker of brain function and of disease…
