Sociological and Cultural Aspects of Tourette Syndrome - Latent Advantages

Latent Advantages

Discussions with adults who have Tourette syndrome reveal that not everyone wants treatment or a "cure", especially if that means they may "lose" something else in the process. Some believe that there may even be latent advantages associated with the genetic vulnerability. Research supports some advantages associated with Tourette syndrome.

A controlled study on a small (13) group of individuals with TS found that cognitive control may be enhanced in young people with Tourette's because the need to suppress tics results in more efficient control of inhibitions. A subsequent study confirmed and extended the paradoxical result that individuals with Tourette's exhibit greater levels of cognitive control than age-matched healthy peers. There is some evidence to support the clinical lore that children with "TS-only" (Tourette syndrome in the absence of other comorbid conditions) are unusually gifted: neuropsychological studies have identified advantages in children with TS-only. A study of full-scale intelligence quotient (IQ) testing showed that children with TS-only had higher IQ scores, relative to their parents, than predicted by statistical models. Another neurological examination of motor function found that 76% of children with TS-only were faster than average on timed motor coordination, although similar results were not found among children with TS who also had ADHD. In a study of eight children, ages 8–17, those with Tourette syndrome were found to be much quicker at processing certain mental grammar skills than children without the condition. The abnormalities that lead to tics may also lead to "other rapid behaviors, including the cognitive processing of rule-governed forms in language and other types of procedural knowledge". The investigator, Michael Ullman, PhD, said, "These children were particularly fast, as well as largely accurate, in certain language tasks. This tells us that their cognitive processing may be altered in ways we have only begun to explore, and moreover in a manner that may provide them with performance that is actually enhanced compared that of typically developing children".
