Age: 2+

Healthy Volunteers: Accepted

Interventions

Electroencephalogram (EEG) Recording

Study Details

Brief summary:

This observational research study is designed to learn more about how the brain processes sound in individuals with Rett syndrome. Participants will complete a noninvasive electroencephalogram (EEG) recording while listening to simple sounds through headphones. In addition, parents or caregivers will complete questionnaires and an interview about the participant's symptoms, communication abilities, daily functioning and overall health. The information collected from this study may help researchers better understand brain activity patterns and clinical features associated with Rett syndrome and support future research efforts.

Interventions and Outcome Measures

Arms

Rett Syndrome Participants

Individuals with Rett syndrome who participate in this observational study will undergo a noninvasive electroencephalogram (EEG) recording while listening to simple sounds through headphones. Parents or caregivers will complete questionnaires and interviews related to the participant's symptoms, communication abilities, daily functioning and overall health. A Rett syndrome severity scale may also be completed by a clinician or trained member of the research team.

Age- and sex-matched controls

Individuals who are age- and sex-matched to Rett syndrome participants in this study will be enrolled as controls. Control participants must have no medical history of genetic, neurological, or psychiatric disorders, no history of special education services, and no hearing impairment. Control participants in this study will undergo a noninvasive electroencephalogram (EEG) recording while listening to simple sounds through headphones. Control participants (or their parent) will also complete a demographics questionnaire.

Interventions

Electroencephalogram (EEG) Recording

Participants will undergo a noninvasive electroencephalogram (EEG) recording to measure brain activity in response to auditory stimuli. During the procedure, participants will listen to simple sounds through headphones while brain signals are recorded. No behavioral responses are required.

Primary outcome measure

  • Mean Auditory Evoked Response Amplitude Measured by EEG [ Time Frame: Assessed at a single study visit (baseline, up to 1 day) ]
  • Mean Auditory Evoked Response Latency Measured by EEG [ Time Frame: Assessed at a single study visit (baseline, up to 1 day) ]
