Which syndrome is characterized by explosive barking and sexual expletives?

Tourette's syndrome is a neurological disorder characterized by a range of involuntary movements and vocalizations known as tics. Among the various types of tics, Tourette's can manifest in ways that include the involuntary utterance of words or phrases, which may sometimes include socially inappropriate remarks or expletives. This particular symptom is referred to as coprolalia and often attracts significant attention due to its disruptive nature.

Individuals with Tourette's syndrome can also display motor tics, such as rapid eye blinking or jerking movements, which coexist with the vocal tics. The presence of both types of tics is what distinguishes Tourette's from other movement disorders. The disorder typically emerges in childhood and is influenced by genetic and environmental factors.

In contrast, tics simply encompass the involuntary movements and sounds without the specific vocalization of socially inappropriate language. Myoclonus consists of sudden, brief jerks or twitches of muscles and is not characterized by vocal components. Hemibalismus involves violent flinging movements of an arm or leg, which is not related to vocal expressions at all. Therefore, the hallmark of Tourette's syndrome—with the inclusion of explosive barking and sexual expletives—clearly identifies it as the correct response
