Tourette Syndrome

A nervous system disorder involving repetitive movements or unwanted sounds.
Tourette syndrome starts in childhood.
It involves uncontrollable repetitive movements or unwanted sounds (tics), such as repeatedly blinking the eyes, shrugging shoulders, or blurting out offensive words.
Treatment may include medication or psychological therapies.


Cluster Number:
Wiki Number: PW217
Diagnosis: Tourette Syndrome
US Patients: 1% of school children and adolescents
World Patients:
Sex Ratio:
Age Onset: Ages 5-7; increases to ages 8-12; then decreases for 2/3 dramatically, can have adult onset or adult recurrence from childhood
Brain Area: dysfunction in neural circuits around the basal ganglia, combines genetic and environmental factors; poor brain circuit connections
Symptoms: Motor tics and vocal tics with blinking, coughing, throat-clearing, sniffing, facial movements. Nearby muscles “urge” first for 90%
Progression: corprolalia (obscene, inappropriate or derogatory remarks) occurs in 10%,; obscene gestures may be “muscular tics” for a few
Causes: Heritable 10X-100X;forceps delivery, paternal age, pregnancy stress, tobacco, caffeine, alcohol or pot during pregnancy, premature
Medications: None

  • Functional tic-like behaviours during the COVID-19 pandemic: Follow-up over 12 months
    by Adriana Prato on January 26, 2023

    CONCLUSION: Our data suggest that several characteristics in clinical course and their phenomenology can help clinicians to distinguish functional tic-like behaviours from organic tics. Our results also suggest a better outcome for tics and anxiety symptoms respect on other comorbidities. A prompt diagnosis and management not only of tics but also comorbidities are recommended, as generally conventional pharmacotherapy for tics does not have positive effects on these patients.

    CONCLUSION: DBS performed by an experienced surgeon is associated with extremely low complication rates.

  • Impact of Tourette's syndrome tics on healing following dental trauma
    by Rakhee Budhdeo on January 25, 2023

    The following case report outlines the impact of motor tics linked to Tourette's syndrome on dental development and healing following a dental injury to a maxillary central incisor. Emergency care and splinting of a mobile extruded maxillary left central incisor tooth was carried out at the local dentist on the same day as the dental trauma. A subsequent referral was made to the paediatric dental department for continued mobility of the maxillary central incisor on splint removal approximately 2...

  • Emerging therapies and recent advances for Tourette syndrome
    by Chih-Yi Chou on January 24, 2023

    Tourette syndrome is the most prevalent hyperkinetic movement disorder in children and can be highly disabling. While the pathomechanism of Tourette syndrome remains largely obscure, recent studies have greatly improved our knowledge about this disease, providing a new perspective in our understanding of this condition. Advances in electrophysiology and neuroimaging have elucidated that there is a reduction in frontal cortical volume and reduction of long rage connectivity to the frontal lobe...
