Symptoms of pediatric Tourette’s syndrome can be categorized into motor tics, vocal tics, imitation of movement, imitation of speech, imitation of expression, and sensory abnormalities. 1. Motor tics: these are sudden involuntary movements, such as blinking, frowning, squinting, opening the mouth, sticking out the tongue, tilting the mouth, nodding the head, shaking the head, shrugging the shoulders, rubbing the hands, clenching the fists, lifting the arms, stretching the legs, standing on tiptoe, bending the knees, throwing out the hands, squatting, and so on. 2. Vocal tics: sniffing, clearing the voice, coughing, screaming, shouting, whistling, repeating phrases, obscene language, etc. 3. Mimicry: stereotypical and mechanical imitation or repetition of other people’s actions, such as seeing others combing their hair will also imitate the action of combing hair. 4. Imitation of speech: stereotypical and mechanical repetition of certain words or sentences, and imitation of the speech of people around them. 5. Mimicry of facial expression: the person may imitate the facial expression of others in a stereotypical way, which may not be in line with the current emotional experience. 6. Sensory abnormalities: A small percentage of people with Tourette’s syndrome will experience some kind of sensory abnormality that needs to be relieved by tic displays, such as burning sensation of the eyes before blinking; tension or pain in the neck muscles, which needs to be relieved by nodding the head and stretching the neck; tightness in the limbs, which needs to be extended by stretching the arms or legs; and nasal obstruction, which needs to be relieved by snorting, etc. This kind of tic disorder is usually not a result of the tic disorder. The manifestation of this tic disorder is usually involuntary, sudden, rapid and non-rhythmic, and may occur in multiple locations and forms. It is recommended that people with the corresponding symptoms consult a doctor in time, and actively pursue treatment after a clear diagnosis.
