Pediatric Trials

Teaching Math Skills to Individuals With Fragile X Syndrome

Children with FXS are predisposed to manifesting a particular profile of intellectual strengths and weaknesses, including specific deficits in math, visual-spatial skills, executive functioning, and social skills. Until now, intensive behavioral interventions have not been targeted to syndrome-specific weaknesses. In the present study we will develop and evaluate behavioral strategies to aid skill acquisition in children with FXS.

Stanford is currently accepting patients for this trial.

  • Behavioral: discrete-trial training

Phase:

N/A

Eligibility


Inclusion Criteria:

   - (a) 10 to 23 years of age (this age range was chosen to maximize the probability that
   subjects will cooperate with the imaging procedures as well as benefit from the
   interventions),

   - (b) in good physical health,

   - (c) able to participate in the imaging component of the project,

   - (d) IQ between 50 and 80. We have found that individuals with IQ's less than 50 points
   are generally unable to comply with the scanning procedures.

   - (e) diagnosis of FXS (for FXS group) and non-specific developmental disorder (for
   control group).

Exclusion Criteria:

Exclusion criteria include

   - contraindications for MRI (e.g., pacemaker, braces),

   - the presence of neurological or sensory problems not associated with the conditions of
   interest (e.g., head trauma, blindness), or inability to discontinue psychotropic
   medication for 4 weeks prior to the scan.

   - Additional exclusion criteria for the control group include the presence of any known
   identifiable syndrome (e.g., fragile X syndrome, Down syndrome, Prader-Willi syndrome,
   Turner syndrome, PKU, fetal alcohol syndrome, Williams syndrome).
