Highlights & Basics
- Tics are brief, sudden, repetitive movements and/or sounds that increase with stress, anxiety, transitions, or excitement.
- Tics occur most commonly in children and adolescents, with boys more frequently affected than girls.
- The exact pathophysiologic mechanisms are unknown, but the disorders are likely to be due to disturbances of the cortico-striatal-thalamo-circuitry.
- Comorbid conditions such as obsessive-compulsive disorder, ADHD, and anxiety are common.
- Tics are often intermittent and mild in children and may not require treatment. Treatment is indicated only for patients whose tics are interfering with activities of daily living or social interactions, or who experience significant tic-related physical pain.
