World’s biggest stutter study
TERRITORIANS aged seven and above with past or present experiences of stuttering are encouraged to volunteer for the nation’s largest ever Genetics of Stuttering Study.
Researchers from the NHMRC Centre of Research Excellence in Speech and Language are calling for 3000 Australians to take part. The study aims to pinpoint genes that may cause stuttering, aiding future research into the causes, treatment and prevention of the disorder.
Co-chief study investigator and speech pathologist Professor Angela Morgan said across the globe, 1 per cent of adults stuttered and nearly 70 per cent of people who stut- tered reported a family history of the disorder.
“Importantly, gender is one of the strongest predisposing factors for stuttering,” she said.
“Boys are two-to-five times more likely to stutter than girls, and they are also less likely to recover spontaneously.”
Volunteers need to fill in a 10-minute online survey and record a short sample of their speech. Those who qualify will be invited to provide a saliva sample for DNA analysis, to help researchers pinpoint the genes that predispose people to stuttering.
