It is not possible to determine that a child has tics by the duration of his/her blinking. Determination of tics needs to be made through behavior, history taking, and diagnostic criteria.
1. Behavior: By communicating with the patient and the patient’s parents to understand his/her learning environment, living environment, hobbies, personality traits, family relationships, major conflicts, teacher-student relationships, academic performance, favorite sports and TV programs, and various events that occurred before and after the emergence of Tourette’s syndrome, in order to learn about his/her etiological profile.
At the same time, observe the performance of tic behaviors and look for environmental factors that cause tics.
2. History taking: To know the past illness, whether there are tics, the duration and treatment, and to ask whether there are any tics in the family.
3. Diagnostic criteria: Repetitive, involuntary, stereotyped, purposeless, and rhythmic motor tics in multiple parts of the body and in multiple forms, accompanied by one or more explosive vocal tics. For example, blinking, squinting, pouting, shrugging, yelling, screaming, repeating statements, obscene language, etc..
And tics every day, many times a day, continuity of more than 1 month. 18 years of age before the onset of the disease, 4 to 7 years of age is the most common, there is no tic disorder other than other physical diseases or mental illness.
If the child has tic symptoms need to take the child to the doctor in time, under the diagnosis of professional doctors, take symptomatic, cause-specific treatment, so as not to delay the condition.
