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 not accepting patients for this trial.

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).
