Just about everyone has met or seen someone who has a tic disorder. Many tic disorders are diagnosed during childhood. Less often, a tic disorder like Tourette syndrome is diagnosed in adulthood — as was the case for Scottish singer Lewis Capaldi.
What are tics?
Tics are very common, with as many as one in five children experiencing them at some point. They can be a motor tic, which is a sudden brief movement — like a shrug, finger tap, or grimace — or they can be a noise, such as a word, grunt, or throat clearing.
In some cases, the movements or noise can be more complex, such as an unusual way of walking, saying particular words, or echoing the words of others (echolalia). Tics are involuntary, although they can sometimes be suppressed.
Tics may be temporary or long-lasting: about a third will go away entirely, a third improve with time (sometimes with treatment, though it’s often not needed), and a third are long-lasting.
