Tourette’s syndrome is strong at night and may be caused by triggers such as shock, infection, bedtime exposure, sleep disorders, and so on. Tourette’s syndrome is a rapid contraction of single or multiple muscles, fixed in one place or wandering, manifested as frowning, facial muscle 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”. It is common in children, and the cause and pathogenesis of the disease are unclear. The tics worsen during stress, decrease during relaxation, and disappear after sleep, so they usually gradually decrease or disappear at night. If there is aggravation at night, it is possible to consider the presence of triggering factors, such as shock (criticism, scolding, etc.), the presence of infections, watching thrilling television and watching television for too long, and disturbances in sleep structure. When you find Tourette’s syndrome is strong at night, you should take the patient to the hospital in time.
