Tic-obstruction syndrome, also known as Tourette’s syndrome or polydactyly. The current diagnosis of the disease is based on the observation of symptoms and the evaluation of the onset history, so parents need to pay close attention to their children’s usual behavior and ask their teachers to assist them at the same time. The diagnosis of the disease is not clinically confirmed by blood analysis or other neurological tests, but only by EEG, CT, MRI or certain laboratory tests to exclude diseases that may be confused with the disease. Therefore, some children with early disease are easily misdiagnosed for the following reasons. 1. The medical subspecialty is too fine, and a few non-neurologists are not too familiar with this disease, plus the early symptoms focus on the strong side, so they may be confused by similar symptoms. The dry cough and throat clearing caused by laryngeal muscle twitching may be misdiagnosed as chronic pharyngitis or bronchitis; blinking and frowning may be misdiagnosed as conjunctivitis; squeezing the nose may be misdiagnosed as chronic rhinitis, etc. 2, parents ignore this disease. Rarely do they see a doctor because they keep blinking and shrugging their shoulders, but they think it’s just a bad habit or playing or doing weird things. When going to the hospital for other illnesses, the doctor happens to find out and asks about the situation, some parents cannot fully cooperate with the answer and are often told “nothing, just a little problem, naughty”. When the doctor told the parents, the parents were not convinced and opposed the consultation, thus delaying the diagnosis. Early on, the child has some ability to suppress the symptoms, so the child can temporarily cover up the twitching symptoms, so that parents and doctors are not easily aware of it. 4. Some doctors have the impression that tic-obscene syndrome must have obscene language, but in fact only 1/3 of the patients appear obscene language phenomenon after a long time of onset.
