About the Study

The purpose of this study is to improve our understanding of how differences in brain activity affect learning, language, and behavior in children with Fragile X syndrome (FXS). Currently, there is no effective treatment for Fragile X syndrome. Our goal is to find brain markers that predict cognitive, language, and behavioral difficulties in young boys and girls with Fragile X syndrome, and to better understand differences in brain activity between children with and without Fragile X syndrome. 

Now includes boys and girls.

Eligibility for Study Participation

  • 32-84 months old with a diagnosis of Fragile X Syndrome based on full mutation of the FMR1 gene.
  • 32-84 months old who are typically developing.

What will I do?

  • Single four hour visit at the Labs of Cognitive Neuroscience at Boston Children’s Hospital.
  • This visit includes clinical and behavioral assessments that will evaluate your child’s thinking, motor skills, language skills, and social communication.
  • In addition, we will measure your child’s brain activity using electroencephalography (EEG). EEG is a safe and radiation-free way to measure brain activity in response to different sounds and pictures.

What will I receive?

  • Families will receive a small toy and $25 for participating and a summary report of the behavioral assessments completed during the visit.
  • We will provide free parking and childcare for siblings.

Study: iBehavior- A Novel Behavior Tracking App Study for individuals with Fragile X syndrome

The T-PAL Lab at the UC Davis MIND Institute is conducting a research study to learn about how we can best measure your child’s behavioral and cognitive functioning in their day-to-day life. Using an iPhone or Android based mobile app at your convenience, you will record your child’s behavior daily for up to 3 weeks. About the Study Who can participate?
