Gilles de la Tourette syndrome, Tourette syndrome - what a fucking nightmare. Affects 1 in every 2,000 kids between the ages of 2 and 21.

It is more likely to occur in boys, especially if they have a first degree relative that also has this disorder.Tics are sudden, repetitive, purposeless motor or vocal expressions or movements. In addition to transient tic disorders and chronic motor tic disorders, Tourette syndrome is a common cause of tics in children. The symptoms of Tourette syndrome include having multiple vocal tics and motor tics, although they don’t have to have both types of tics at the same time.

Children with vocal tics may make compulsive barking and grunting noises, have frequent throat clearing, coughing or sniffling, echolalia (vocal tics characterized by repeating words that a child hears), and/or coprolalia (vocal tics characterized by repeating or shouting obscene words), although coprolalia is rare.
Other common motor tics include eye blinking, jerking the head, movements of the eyes, different facial expressions, including grimacing, and nose twitching.

Simple tics are brief and involve only a few muscle groups. At first, children with Tourette syndrome usually have simple tics, but over time these tics can become more complex, becoming longer and involving several different muscle groups or whole words or phrases.

I think my dog has Tourette’s.
