Abstract
AbstractObjective Tourette syndrome (TS) and autism spectrum disorder (ASD) share clinical features and possibly an overlapping etiology. This study: 1) examined ASD symptom rates in participants with TS and 2) characterized the relationships between ASD symptom patterns and TS, obsessive-compulsive disorder (OCD), and attention-deficit/hyperactivity disorder (ADHD). Method Participants with TS (n = 535) and their family members (n =234) recruited for genetic studies reported TS, OCD, and ADHD symptoms and completed the Social Responsiveness Scale Second Edition (SRS), which was used to characterize ASD symptoms. Results SRS scores in participants with TS were similar to those observed in other clinical samples but lower than in ASD samples (mean SRS total raw score = 51; SD=32.4). More children with TS met cut-off criteria for ASD (22.8%) than adults with TS (8.7%). The elevated rate in children was primarily due to high scores on the SRS Repetitive and Restricted Behaviors (RRB) subscale. Total SRS scores were correlated with TS (r=0.27), OCD (r=0.37), and ADHD (r=0.44) and were higher among individuals with OCD symptom-based phenotypes than for those with tics alone. Conclusion Higher observed rates of ASD among children affected by TS may in part be due to difficulty in discriminating complex tics and OCD symptoms from ASD symptoms. Careful examination of ASD-specific symptom patterns (social communication vs. repetitive behaviors) is essential. Independent of ASD, the SRS may be a useful tool for identifying patients with TS with impairments in social communication, potentially putting them at risk for bullying and other negative sequelae.
