Health professionals look at the person’s symptoms to diagnose TS and other tic disorders. There is no single test, like a blood test, to diagnose TS. 1Īlthough the media often portray people with TS as involuntarily shouting out swear words (called coprolalia) or constantly repeating the words of other people (called echolalia), these symptoms are rare, and are not required for a diagnosis of TS. However, many people with TS experience tics into adulthood and, in some cases, tics can become worse during adulthood. In most cases, tics decrease during adolescence and early adulthood, and sometimes disappear entirely. Even though the symptoms might appear, disappear, and reappear, these conditions are considered chronic. The types of tics and how often a person has tics changes a lot over time. They tend to improve when a person is calm or focused on an activity. Tics usually are worse during times that are stressful or exciting. The first symptoms often are motor tics that occur in the head and neck area. Symptoms usually begin when a child is 5 to 10 years of age. It's worth noting that the ancient Romans also demonstrated their approval of public performance with finger-snapping and that modern Canadian concertgoers signal delight by screeching at the organ-grinder's monkey.The main symptoms of TS are tics. 'You see it at the end of a lot of plays by Plautus and Terence, where they have this word plaudite, which is an imperative 'applause,' 'clap.'' But the motion of clapping, I think that's a learned behavior.'Īs to clapping's association with audience approval, Jay Fisher, a classics professor at Yale University, dates the custom to at least the third century B.C. What I've seen babies do spontaneously, from excitement, is clasp their hands together. Yvette Blanchard, a pediatric physical therapist, and researcher at the University of Hartford says that human clappers are made, not born. It's not to applaud something it's because they're frightened or want to call attention to food. But you don't find primates doing it unless they've been taught to do it. Cavemen and human ancestors - we don't know whether they clapped hands or not. We don't know how far back it goes, not without a time machine.
