Tics wax and wane, follow a premonitory urge, and frequently co-occur with ADHD and OCD.","answer_md":"*A child who blinks, sniffs and clears the throat in shifting combinations is rarely being difficult — they may be describing a tic disorder.*\n\n## In short\nTourette Syndrome (ICD-11 **8A05.00**) is a chronic tic disorder defined by **multiple motor tics and at least one phonic (vocal) tic**, present for **more than one year**, with onset before age 18 — typically emerging between **4 and 8 years**. Tics are sudden, rapid, recurrent, non-rhythmic movements or vocalisations; they need not occur concurrently. It is classified among neurodevelopmental disorders, reflecting its developmental, often familial, basis.\n\n## ICD-11 features in early childhood\n- **Motor tics first**: simple motor tics — eye-blinking, facial grimacing, head jerks, shoulder shrugs — usually precede phonic tics (sniffing, throat-clearing, grunting) by months to years.\n- **Waxing and waning**: severity fluctuates; tics often worsen with excitement, fatigue or stress and may transiently suppress with effort, followed by rebound.\n- **Premonitory urge**: an uncomfortable sensory precursor relieved by the tic — frequently under-reported by young children.\n- **High comorbidity**: ADHD and OCD/obsessive-compulsive features commonly co-occur and often shape functional impact more than the tics themselves.\n- Exclude tics due to substances, Sydenham chorea or other neurological conditions.\n\n## The Pinnacle way\nDevelopmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from a checklist or an app. Our teams profile co-occurring attention and regulation needs alongside the [tic presentation itself](https://pinnacleblooms.org/ask/tourette-syndrome), supporting families through [behavioural therapy](/behavioural-therapy) and a [structured developmental baseline](/ask/what-is-the-abilityscore-and-how-is-it-calculated).\n\n## Trusted sources\nWHO ICD-11 (8A05.00, Tourette syndrome); WHO neurodevelopmental disorders framework; AAP guidance on tic disorders in childhood.\n\n**Next step —** Refer a child with persistent multi-site tics for a structured developmental and comorbidity assessment at a Pinnacle centre.\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/what-is-tourette-syndrome-and-what-are-its-icd-11-features-in-early-childhood","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU
