There is a disease called Tourette’s syndrome, also known as Tourette’s syndrome, which starts in children aged 3 to 10 years old, most of them aged 4 to 7 years old, mainly manifesting an involuntary, sudden, rapid, recurrent, non-purposeful, non-articulated movement or vocalization. The main clinical manifestations of Tourette’s syndrome are progressive development of multiple sites and forms of motor tics and one or more vocal tics, and the co-existence of motor and vocal tics. The symptoms usually start with a single motor twitch of the eyes and face (blinking), which is sporadic, and then gradually progress to twitches of the neck, shoulders, limbs, and trunk (nodding, shrugging, striking, kicking, etc.), which persist. The twitching and obscene symptoms involve many parts of the body and are frequent, which have a greater emotional and psychological impact on the child. About half of the children have obsessive-compulsive symptoms, half have attention deficit and hyperactivity disorder symptoms, and some have self-injurious behavior, mood disorders or learning difficulties. Professor Wang reminded that the condition of children with Tourette’s syndrome is often fluctuating, sometimes mild and sometimes severe, and sometimes may resolve on its own for a period of time. The site, frequency and intensity of the twitching may change, and may increase when the child is stressed, anxious, fatigued, or sleep deprived, and decrease when the child is relaxed, or disappear after sleep. Tic disorder is not a so-called bad problem, but it can be harmful, and some children with the disease can be accompanied by inattention, learning difficulties, emotional disorders and other psychological problems. Currently, in terms of treatment, there are medications as well as surgical treatments. Common medications include aripiprazole, haloperidol, etc. Many medications are also attempts to treat and try to improve some of the symptoms in some affected children. Medications can be started in small doses, slowly increasing the dosage to reduce side effects. When there is only partial improvement of symptoms with a single medication or when there are complex concomitant symptoms of tic obscura syndrome, deep brain electrical stimulation treatment can be considered to improve the child’s symptoms by stimulating the relevant neural nuclei with microcurrent and improving the pattern of abnormal discharge. Brain pacemaker therapy for tic disorder is currently the best internationally recognized treatment for tic disorder, and it has a high success rate in the treatment of Tourette’s syndrome, which avoids the side effects of medication and prevents recurrence of the disease.
