Males are about three to four times more likely than females to develop Tourette syndrome. Having a family history of Tourette syndrome or other tic disorders might increase the risk of developing Tourette syndrome. Risk factors for Tourette syndrome include: Chemicals in the brain that transmit nerve impulses (neurotransmitters), including dopamine and serotonin, might play a role. It's a complex disorder likely caused by a combination of inherited (genetic) and environmental factors.
The exact cause of Tourette syndrome isn't known. But whenever a child shows unusual behavior, it's important to identify the cause and rule out serious health problems. Many children develop tics that go away on their own after a few weeks or months. See your child's pediatrician if you notice your child displaying involuntary movements or sounds. With great effort, some people with Tourette syndrome can temporarily stop or hold back a tic. Worsen in the early teenage years and improve during the transition into adulthoodīefore the onset of motor or vocal tics, you'll likely experience an uncomfortable bodily sensation (premonitory urge) such as an itch, a tingle or tension.Worsen if you're ill, stressed, anxious, tired or excited.Common motor tics seen in Tourette syndrome Simple ticsĬommon vocal tics seen in Tourette syndrome Simple tics But the spectrum of tics that people experience is diverse. Motor tics usually begin before vocal tics do. Tics can also involve movement (motor tics) or sounds (vocal tics). These distinct, coordinated patterns of movements involve several muscle groups. These sudden, brief and repetitive tics involve a limited number of muscle groups. Severe symptoms might significantly interfere with communication, daily functioning and quality of life. Tics - sudden, brief, intermittent movements or sounds - are the hallmark sign of Tourette syndrome.
