What is Tourette’s syndrome? -

Tourette's syndrome is a condition that affects an individual's nervous system, and causes involuntary movements or sounds known as tics. Except in extreme cases, these tics are inconvenient but ultimately harmless, and there is no link between Tourette's and the lifespan or intelligence of those afflicted by it. The condition was named by French neurologist Jean-Martin Charcot (pictured) after his intern who first studied these tics in his patients.

How is it treated? -

While severe, debilitating cases of Tourette's are rare, mild forms of the condition can be at least partially treated using a combination of dopamine-inhibiting medications and therapy. Many doctors agree that cognitive behavioral therapy with a focus on habit reversal is the most effective treatment to soothe or eliminate tics.

Is there a cure? -

Despite these available treatments, there is no cure-all method or procedure to completely eliminate Tourette's syndrome. Studies show that individuals who show signs of Tourette's syndrome as children usually see their symptoms diminish as they go through puberty, and in some cases the tics become imperceptible. So imperceptible, in fact, you might have never noticed that some of your favorite celebrities live with Tourette's.
