New insights into managing tics and correcting common misconceptions about Tourette syndrome

Recent updates highlight the developmental nature of tics, debunk stereotypes, and emphasise effective behavioural treatments for those affected by Tourette syndrome and related tic disorders.

Tics are sudden, repeated movements or sounds that are hard to suppress, and they usually begin in early childhood, often between the ages of 4 and 6. The Canadian Psychological Association says they can be motor tics, such as blinking or shoulder shrugging, or vocal tics, such as throat clearing or sniffing, and that many people feel a build-up of tension or urge before a tic, followed by relief afterwards. The CDC likewise describes tics as involuntary and notes that their intensity can fluctuate over time, sometimes easing for weeks or months before returning.

Tourette disorder, also known as Tourette syndrome, is diagnosed when both multiple motor tics and at least one vocal tic have been present for more than a year and the condition starts before age 18. The CDC says persistent motor or vocal tic disorder involves only one type of tic lasting at least a year, while provisional tic disorder covers symptoms present for less than a year. These distinctions matter because treatment and support often depend on how long symptoms have been present and how much they affect daily life.

The fact sheet stresses that tics are not deliberate, even if some people can briefly hold them back. It also pushes back on the common stereotype that all vocal tics involve swearing. The CDC says coprolalia is far less common than television depictions suggest, and the Canadian Psychological Association puts the figure at about 10% of people with Tourette syndrome. Another common myth is that tics are only a childhood problem; in reality, the disorder is developmental, even if symptoms often ease in adolescence.

Behavioural therapies are usually the first option when tics need treatment. The Canadian Psychological Association highlights habit reversal training and comprehensive behavioural intervention for tics, both of which teach people to recognise an oncoming tic and use a competing response. Parent training can also help children, especially when combined with those approaches. Medication may be considered when symptoms are severe, while deep brain stimulation remains a rare experimental option for the most difficult cases.
