Real-life-type problem solving in Tourette syndrome.

OBJECTIVE

The main objective of the study was to examine social problem solving in real-life-type situations in Tourette syndrome (TS).

BACKGROUND

Studies of cognitive functioning in TS have usually focused on nonsocial, abstract tasks, with mixed findings as to whether there is evidence of impairment in executive functions in those without comorbid disorders. The current study focuses primarily on social functioning, using a problem-solving task known to be sensitive to frontal lobe lesions.

METHODS

TS participants without comorbid diagnoses were compared with matched healthy control participants on a problem-solving task, using a range of interpersonal problem scenarios presented on video. A set of more abstract executive tests was also included.

RESULTS

Participants with TS were found to perform below a matched control group on the problem-solving task both in generating a range of potential problem solutions, and in selecting appropriate final solutions. They also performed more poorly on aspects of executive function.

CONCLUSIONS

This study provides evidence of difficulties in both social and nonsocial aspects of functioning in TS. The implications of the findings for our understanding of TS and problem solving are discussed.
