The host: I read on the Internet that early detection of Tourette’s syndrome is needed, so what is the need for early detection of Tourette’s syndrome? Ren Yanling: Early detection of the child’s symptoms allows us to find the cause in time, for example, to find out whether there are some psychosocial factors, and if these factors are stopped in time, the effect will be better. The early detection can be treated in time to prevent the child’s transient tics from developing into a chronic tic disorder. If it develops into a chronic tic, or if it develops into a Tourette’s syndrome, the treatment will not be very effective. Tic disorder is a chronic condition that recurs repeatedly, and the longer it takes, the lower the chances of cure.
