Adolescent Gender Differences in Tic- and Non-Tic-Related Impairments in Tourette Syndrome.

ABSTRACT

We aimed to compare tic- and non-tic-related impairment experienced by adolescent girls and boys (ages 13 through 17) with Tourette syndrome and associations with age. We extracted from the electronic health record child and parental responses to the mini-Child Tourette Syndrome Impairment Scale (mini-CTIM) and other questionnaire data reflective of tic- and non-tic-related impairment of adolescents with Tourette syndrome presenting to our clinic over a 12-month period. We identified a total of 132 (49 female, 83 male) unique adolescent encounters. Mini-CTIM scores did not differ significantly between genders. Tic- and non-tic-related impairment were lower in older boys, but not older girls. Obsessive-compulsive symptoms correlated with parent-reported non-tic-related impairment experienced by adolescent girls but not boys. During adolescence, tic- and non-tic-related impairments may be less likely to improve with age in girls. Future longitudinal studies are needed to confirm this finding.
