Understanding disability in Tourette syndrome.

Area of Science:

• Pediatric neurology
• Child psychology
• Neurodevelopmental disorders

Background:

• Tourette syndrome (TS) often co-occurs with attention-deficit-hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD).
• Understanding the impact of these co-occurring conditions on children's health and well-being is essential for effective management.

Purpose of the Study:

• To investigate the disability experience in children with Tourette syndrome, considering the presence of ADHD and/or OCD.
• To identify specific health domains affected by these co-occurring conditions.

Main Methods:

• Seventy-one children with TS (with or without ADHD/OCD) were analyzed across four subgroups.
• Clinicians collected baseline information and symptom severity. Parents completed the Child Health Questionnaire.

Main Results:

• Children with TS+ADHD and TS+ADHD+OCD showed significantly lower psychosocial domain scores compared to national norms.
• ADHD symptom severity was the most significant predictor of psychosocial impairment (R(2)=0.55, p<0.001).
• Children with TS only did not differ from norms in most psychosocial domains, except for family activities.

Conclusions:

• Children with TS and co-occurring ADHD and/or OCD experience widespread psychosocial health impairment.
• For children with TS alone, psychosocial health is largely comparable to the general population.
• Treatment of ADHD and OCD should be prioritized in children with multiple diagnoses for improved psychosocial outcomes.
