How many people in the world have TS?

Tourette Syndrome (TS) affects approximately 1 in 100 children, which translates to about 1% of the population. Given the global population of over 7 billion, this suggests that around 70 million people may have TS worldwide. However, prevalence can vary based on factors such as geography and diagnostic practices. It's important to note that many cases may go undiagnosed or unreported.
