Early signs of Tourette Syndrome in an 18–24-month-old

Many toddlers blink hard, scrunch their nose, or make funny little sounds — so when is a tic actually Tourette Syndrome, and is 18–24 months even the age to worry?

In short

Honestly, 18 to 24 months is too early to identify Tourette Syndrome. Tics most often first appear between ages 4 and 6, and a Tourette Syndrome diagnosis requires multiple motor tics plus at least one vocal tic, persisting for over a year — a pattern that simply cannot be established in a toddler this young. At this age, brief eye-blinking, head movements or throat sounds are usually ordinary, transient and part of normal development. The sensible step is to observe calmly and bring any concerns to a routine developmental check — not to go looking for a frightening list of signs.

What is actually appropriate to observe at 18–24 months

Toddlers move, fidget, mimic and experiment with their bodies constantly — this is healthy. Rather than hunting for "tics", it helps to simply notice your child's overall development:

• Movement and coordination — walking steadily, climbing, beginning to run, scribbling
• Communication — building a growing vocabulary, pointing to show you things, following simple requests
• Connection and play — eye contact, shared smiles, imitation, interest in other people
• Settling and routines — feeding, sleeping and self-soothing patterns

Repetitive blinks, grimaces or grunts at this age are very often temporary habits or responses to tiredness, excitement, dryness or a passing illness — and they usually fade on their own. They are not evidence of Tourette Syndrome.

When tics and a Tourette assessment become meaningful

Tic disorders, including Tourette Syndrome (ICD-11 8A05.00), are generally recognised in school-aged children, most often from 4–6 years onwards. A clinician looks for tics that have been present for a sustained period, that change over time, and that combine both movement and sound tics. Before then, watch-and-monitor is the right stance.

Do bring it to your paediatrician sooner if movements are forceful, painful, cause falls or injury, involve stiffening or jerking with loss of awareness, or come with developmental regression — these warrant prompt medical review to rule out other causes, separate from any tic question.
