The cause of Tourette’s syndrome is hitherto unknown and is thought to be a neurological disorder. Tourette’s syndrome causes people to twitch. It is characterized by sudden jerks, movements or sounds that the person does involuntarily, for example, a person may blink continuously or make involuntary grunting sounds. Twitching is a bit like hiccups. Even though we don’t want to hiccup, our body does it anyway. Sometimes we can stop briefly, but this is difficult. The core symptom of Tourette’s syndrome is twitching, and the first symptom to appear is a motor twitch that occurs in the head and face. The tics are often worse in stressful and exciting situations, and often improve when you are calm or focused on something. The type of twitching and the frequency of twitching often vary, even though twitching symptoms may appear, disappear, and reappear, and these symptoms are considered chronic. The diagnosis of Tourette’s syndrome relies mainly on symptomatological diagnosis rather than blood tests, etc. Although there is no cure, there are many treatments that can help manage tics, such as medication and behavioral therapy that have been studied and proven to be effective. Tourette’s syndrome is often combined with other disorders, with 79% having at least one psychiatric, behavioral or developmental disorder. The two most frequent comorbid disorders are ADHD and OCD. 1. Tourette’s syndrome is a complex neuromotor disorder associated with chemical imbalance in the brain. 2. The main manifestations are involuntary movements and vocalizations. 3. The incidence is 3-4 times higher in boys than in girls. 4.There is no cure so far. 5. Tourette’s syndrome is hereditary. 6. Tourette’s syndrome is not a progressive deteriorating disease. (This is good news.) 7. Some genes may cause Tourette’s syndrome, although only one has been identified so far. 8. There is no medical test to diagnose Tourette’s syndrome. In fact, the process of medication for Tourette’s syndrome is a continuous process of measuring the benefit/risk ratio. Drug selection should not only consider effectiveness but also focus on drug side effects. The current expert consensus is that patients with severe tics should be treated with medication. The goal of pharmacotherapy is to reduce tics rather than eliminate them completely, which would eliminate the damage they cause. The desire to completely control tic symptoms often leads to overdosing with medications that can cause more problematic side effects than tics.
