Answer:
The most likely diagnosis is Tourette's syndrome.
Step-by-step explanation:
Tourette's syndrome usually begins in childhood, has a chronic course and a dysfunctional or disabling character. The initial symptoms consist of motor tics of the head and face that subsequently spread progressively to the trunk and lower extremities, without having to fulfill the cephalocaudal progression of motor tics in all cases, and it is difficult to distinguish them primarily from a picture of transient tics, and one or more vocal tics, vocal tics may appear at a given moment, in isolation, and the same with multiple motor tics. Motor tics include, but are not limited to: grimacing, gesturing, blinking, eyebrow raising, neck twitching. In the case of vocal tics, these include: repetitive emission of sounds and words, throat clearing, screaming, various guttural sounds.
