Tic disorder, whose full name is Tourette’s syndrome, is an involuntary movement disorder that occurs more easily in children and adolescents. The cause of this disorder is not completely clear, but it is considered to be related to mental tension and psychological stress, and the symptoms of mental tension and anxiety may become more pronounced when the patient is frustrated or scolded. The most common manifestation of this disease is involuntary head movements, which can be manifested as head shaking, eye squeezing, mouth pouting, tongue out, making faces, and in more serious cases, involuntary movements of the limbs, similar to dance-like movements. If this condition affects daily life and study, it is recommended to take medication for symptomatic treatment. The most commonly used medication is haloperidol, which is usually maintained for about 3 months, and most patients’ symptoms can be relieved, after which the dosage can be reduced and withdrawn.
