The webinar by Prof Carol Mathews addresses the relationship between Tourette syndrome and autism spectrum disorder (ASD), focusing on their clinical overlap, shared neurodevelopmental features, and diagnostic challenges.
The presentation reviews current evidence on the prevalence of autistic traits in individuals with Tourette syndrome and discusses common comorbidities, including ADHD, OCD, and anxiety disorders.
Particular attention is given to the differentiation between tics, stereotypies, and other repetitive behaviours. The webinar also highlights emerging research on genetic and neurobiological mechanisms underlying both conditions and discusses implications for clinical assessment and multidisciplinary management.
Dr Mathews is the Donald R. Dizney Chair in Psychiatry, Professor, Director of the Center for OCD, Anxiety and Related Disorders (COARD), and the Interim Director for the UF Health Center for Neurodevelopment for the Department (CAN) of Psychiatry at the University of Florida.
As the Director for COARD her research and clinical interests center around identifying the causes and neural underpinnings of obsessive compulsive and anxiety spectrum disorders, including OCD, hoarding disorder, tic disorders, and grooming disorders. She is actively engaged in studying the genetic causes of Tourette Syndrome (TS) and OC spectrum disorders, as well as examining how individuals with these disorders process information using standard neuropsychological assessments, electrophysiological methods such as EEG, and neuroimaging. She is also the principal investigator of a large study comparing community-based behavioral treatment for hoarding disorder to the current standard of care, group treatment by psychologists. She hopes that ultimately, this information will help to refine diagnosis, prevention, and intervention for these disorders. She serves on several advisory boards for non-profit organisations, including the Tourette Association of America, the International OCD Foundation, and the MHASF Task Force on Hoarding and Cluttering. She is also the chair of the TS/OCD Workgroup of the Psychiatric Genomics Consortium (PGC).
