After Tourette’s syndrome is cured, the intelligence is still the same as before. Tourette’s syndrome is a rapid contraction of single or multiple muscles, fixed in one place or wandering, manifested by eye-rolling, facial twitching, nasal flaring, pouting. 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, the cause and pathogenesis are not clear, some cases are caused by basal nucleus lesions, and some are related to genetic and psychiatric factors. 85% of the children have mild to moderate behavioral abnormalities, which are manifested as inattentiveness, restlessness, obsessive-compulsive behavior, obscene behaviors, or destructive behaviors. The tics are aggravated by stress, relieved by relaxation, and disappear after sleep. The child’s intelligence is not affected. Therefore, after the tics are cured, the intelligence is the same as before. When tics are present, they should be treated in a timely manner, with psychological counseling and, if necessary, medication.
