Tourette Syndrome: Lifelong Neurodevelopmental Condition

Tourette Syndrome (TS) is a lifelong neurodevelopmental disorder characterized by multiple motor tics and ≥1 vocal tic persisting >1 year, onset <18 years.

Clinical Course

• Onset: Typically 5–7 years; peak severity 10–12 years.
• Trajectory: ~50% have significant improvement by late adolescence; ~10–15% persistent severe.
• Comorbidities: ADHD (50–60%), OCD (30–50%), anxiety, learning disabilities.

Management

• Psychoeducation for patient/family/school.
• Behavioral: CBIT (Comprehensive Behavioral Intervention for Tics) – first-line.
• Pharmacologic: Alpha-2 agonists (guanfacine, clonidine), antipsychotics (risperidone, aripiprazole) for severe tics.
• DBS: Investigational for refractory adults.

Prognosis

Normal lifespan, intelligence. Many lead fulfilling lives; tics often become less impairing. Support groups (TSA) valuable.
