The words “naughty”, “naughty”, “mischief” are often used to describe a child who is active and playful, some children often make teachers and adults angry, as children grow up, gradually As children grow up, they become more aware, naughty, mischievous and less mischievous, but there may be a child who still makes teachers and parents “worried”. Some parents find that their children are abnormal, they may first look it up on the Internet, and then bring it to the hospital clinic to see a doctor, ranging from a few years old to a dozen or even 20 years old. Nodding, shrugging, eyebrow squeezing, belly puffing, strange noises, hand fluttering and other movements are all present and vary from patient to patient. If a child has sudden, rapid, uncontrolled muscle twitching, the child may have a condition called Tourette’s syndrome, which starts between the ages of 2 and 15. Motor tics: The first tics are usually on the face, and are characterized by rapid and repeated irregular tics of the eyes and facial muscles, such as blinking, nose twitching, and “grimacing”, and later motor tics in other areas, such as head tossing, head nodding, rapid and short neck extension, and shoulder shrugging. The symptoms may gradually develop to the upper limbs, trunk or lower limbs, with brief, violent involuntary movements of the limbs or trunk, such as throwing movements of the upper limbs, kicking, kneeling, bending the knees, stubbing the feet or bending and twisting movements of the trunk. Some patients even hit people (themselves or others) aimlessly, touch their own or others’ bodies, and bizarrely imitate the movements of others. Vocal tics: These can be simple vocal tics, or they can make strange sounds, such as dry coughing sounds in the throat, or overwhelming sounds such as barking, grunting, or “smacking”. “tongue smacking” and other sounds. Nasal twitching then appears as frequent snorting, panting, choking sounds, etc. Obscene speech disorder: cursing sounds and swearing occur. Patients tend to have good self-awareness, but have difficulty in self-control. Vocal tics often occur in conversations with people, especially at pauses in speech. The frequency of tics is particularly high when the patient is under the influence of emotions or when it is related to personality and sexuality. In some patients, repetition of speech occurs for fear that the meaning of their speech will be unclear, producing a clinical repetition of speech. The tics that appear at the beginning of the disease may be related to uncomfortable thought feelings and later progress to isolated occurrences without any conscious involvement. Behavioral disturbances: in mild cases, the patient may be restless, overly sensitive, irritable or behaviorally withdrawn; in severe cases, the patient may exhibit compulsive behaviors that are difficult to escape from, often repeating an action irresistibly, such as repeatedly washing hands, counting numbers and checking door locks. Some patients exhibit distractibility, hyperactivity, emotional instability, and fidgeting, called attention deficit hyperactivity disorder. Some patients also exhibit disruptive behavior, showing sudden uncontrollable impulsive behavior, such as excessive provocative behavior, or even violent and self-injurious behavior. Examples include biting one’s lips and cheeks and hitting one’s head against hard objects. Approximately 75% of patients have learning problems and reduced learning ability, especially with perceptual difficulties in reading, writing and composition, and even inability to complete normal schooling. The cause of Tourette’s syndrome is not known, but it may be related to brain development. The disease is self-limiting, and most patients’ symptoms will disappear in adulthood. Patients can sometimes self-suppress the tics for short periods of time during the onset, while excitement and stress make them worse and disappear during sleep. If the symptoms of tics are severe, they can be controlled with drugs such as aripiprazole and haloperidol. In addition, avoid putting too much mental burden on the child and reduce the child’s exposure to electronic products, especially reducing the viewing of overly intense and stimulating images. For medically refractory tics, brain pacemaker surgery is also a viable treatment option.
