Tourette syndrome is a neurological disorder characterized by involuntary, repetitive movements and sounds, known as tics. Tics are sudden, uncontrollable motor actions (e.g., blinking, shoulder shrugging) or vocalizations (e.g., throat clearing, making sounds). This syndrome typically emerges between the ages of 5 and 9 and is more prevalent in boys. The etiology of Tourette syndrome is multifactorial; genetic predisposition, imbalances in brain chemicals (particularly dopamine metabolism), and environmental factors (rarely bacterial infections) can play a role in its development. The disorder is recognized to have a genetic basis; genetic variations can be inherited from parents or may arise spontaneously during the intrauterine period. Differences in dopamine-related neural networks in the brain are also associated with Tourette syndrome.
