What is the purpose of this trial?

This trial aims to identify new markers that might help track or understand Rett Syndrome, a rare neurological disorder. Researchers seek to determine if these markers change with symptoms and remain stable when symptoms do not. Participants will undergo an EEG test, which measures brain activity, and the results will be compared with those of typically developing individuals. The study seeks girls with Rett Syndrome or a specific genetic variant associated with it, as well as typically developing girls with no cognitive issues.

As an unphased study, this research offers participants the opportunity to contribute to a deeper understanding of Rett Syndrome, potentially leading to better diagnostic tools in the future.

What prior data suggests that this EEG method is safe for participants?

In a previous study, researchers examined how well people tolerated certain treatments for Rett Syndrome. For example, one study on the drug Trofinetide found it was generally safe. Some participants reported side effects, but these were mostly mild. Another study on the gene therapy NGN-401 also showed that young girls with Rett Syndrome tolerated the treatment well.

This particular study does not involve a new treatment. Instead, it uses an electroencephalogram (EEG) to measure brain activity. EEGs are non-invasive, meaning they don't involve surgery or entering the body, and are commonly used in medical settings. They are considered safe and usually do not cause any harm or discomfort.

Overall, research suggests that the methods used in this study are safe for participants. Those considering participation should consult with their doctor to understand any personal health considerations. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the trial on neurophysiologic biomarkers in Rett Syndrome because it aims to uncover new ways to understand this complex condition. Unlike existing treatments that primarily address symptoms like seizures or breathing issues, this study seeks to identify specific biomarkers that could lead to earlier diagnosis and personalized treatment strategies. By focusing on neurophysiologic changes, researchers hope to pave the way for innovative therapeutic approaches that could improve quality of life for those with Rett Syndrome.
