The cause of tics is unknown and may be related to dopaminergic and 5-hydroxytryptaminergic overactivity or dopamine receptor hypersensitivity. Tourette’s syndrome consists of rapid contraction of a single or multiple muscles, either in one place or in a wandering manner, and is manifested by frowning, facial twitching, nasal flaring, and puckering of the lips. If the respiratory and articulatory muscles are involved, the tics may be accompanied by involuntary articulation or obscene language, so it is called “Tourette’s syndrome”. This disease is common in children, and the etiology and pathogenesis of the disease are not clear, but may be related to genetic, environmental and psychiatric factors. Application of dopamine receptor antagonists or dopamine depleting agents and selective 5-hydroxytryptamine reuptake inhibitors can effectively control the tic symptoms, suggesting that striatal dopaminergic and 5-hydroxytryptaminergic hyperactivity or dopamine receptor hypersensitivity may be related to it. Medication combined with psychological counseling is an effective treatment for this disorder, and standardized treatment can lead to normalization in many children. When tics are detected, it is recommended to seek medical treatment in time to avoid delaying the condition.
