Neuropsychological functioning in children with Tourette syndrome (TS).
OBJECTIVE
We examined whether children with Tourette syndrome (TS) displayed a unique pattern of neuropsychological deficits on the CANTAB relative to control children. We also looked at whether children with TS and other comorbidities had more neuropsychological impairments than those with uncomplicated TS and how age was related to the profile of neuropsychological deficits in TS.


METHODS
Participants included 38 children with TS (aged 7 to 13 years) and 38 control children (aged 6 to 12 years). All children were administered 8 subtests from the CANTAB and parents and teachers completed the BRIEF rating scale on children in the TS group.


RESULTS
Children with TS displayed deficits relative to control children on measures of visual memory, executive functioning, and attention from the CANTAB. Among the TS group, age was negatively correlated with performance on measures of executive functioning, speed of response and working memory.


CONCLUSIONS
Identifying the pattern of neuropsychological deficits in children with TS on the CANTAB is important for highlighting areas of deficit that can be targeted for intervention and teaching strategies. With further research, the CANTAB may prove to be a useful resource in the assessment and treatment of children with TS.
