Ryleigh Hawkins was a bright, social 15-year-old enjoying an annual school sports day when she recalls making an unusual motion, flicking her head to the side. At the time, she didn't realise it was involuntary. And certainly didn't think it might be the beginning of a condition that would change her life.
In the days that followed, she began making involuntary vocal sounds - to the point her teachers at Timaru Girls High School became so concerned they sent her to hospital.
A CT scan came back clear. Tourette's was suspected, but can't be diagnosed before a year of symptoms are documented.
By the time Ryleigh reached Year 12, she had begun swearing uncontrollably too. A week before her 16th birthday, Ryleigh Hawkins was diagnosed with Tourette Syndrome, a neurological disorder categorised by involuntary physical and vocal tics.
"I was in disbelief," Ryleigh, now 18, tells the Herald. "It usually comes up around the age of eight to 10."
