What is Tourette’s Syndrome?

About this episode

What is Tourette’s Syndrome? Thanks for asking! Tourette’s syndrome is a neurodevelopmental disorder which usually begins in childhood. It’s estimated that around 1% of all school-age children and teenagers have Tourette’s, with boys several times more likely to be affected than girls. The main symptoms are involuntary sounds and movements known as tics. Some examples of physical tics are blinking, grimacing and shoulder shrugging. Meanwhile, vocal tics can be as simple as coughing or sniffing, or more complex like saying random words. More rarely, people may repeat sounds or sentences which can include obscenities. While it is often associated with the syndrome in the eyes of the public, swearing only actually affects around one in ten people with Tourette’s. The syndrome was named by French neurologist Jean-Martin Charcot, after his student Georges Gilles de la Tourette. What causes people to have Tourette’s? The causes and origins are still somewhat unknown. It’s suspected that a dysfunction in certain parts of the brain leads to abnormal activity of the neurotransmitter dopamine. Aside from being linked to reward and pleasure, dopamine is responsible for controlling body movements. Genetic factors also have a role to play; studies have shown that Tourette’s is highly heritable. Nevertheless, no single gene has been identified as the cause and it’s likely that many different ones are responsible. If the tics aren’t permanent, how do they appear?
