Spotlight: Participant Rich talks about his experiences with stuttering

By MCRI | Nov 12, 2019

Rich Stephens talks about his experiences with stuttering, and the power of not feeling alone. He feels strongly that “stuttering should never be a taboo subject”. He believes that “to understand anything you need to start at the beginning. Which is why The Genetics of Stuttering Study is so important for the future generations of people who stutter.”

Fantastic to hear about @JohnGHendy's new book on #stuttering! He is keen to speak with PWS - particularly underrepresented groups. If you have a story to tell - get in touch! https://t.co/SAbKnyKXez

I never really wrote (or even spoke) about my stutter until I interviewed Biden last fall. And I never expected stutterers all over the world to send me letters about their own lifelong struggles with this disorder. I’m deeply humbled and grateful to work with @aaknopf on this: https://t.co/PLZ4SBzuog

Annie Glenn, as a person who stuttered, was a champion for many in the #stuttering community. Thrown into the public spotlight as the wife of astronaut and senatorJohn Glenn, she used this prominence to advocate for PWS and to change the public perception of stuttering.


About the 'Genetics of Stuttering Study’

The 'Genetics of Stuttering Study’ aims to pinpoint the genes that predispose individuals to stuttering, which could revolutionise future research into the causes, treatment and prevention of the disorder.

Stuttering or stammering affects verbal communication – particularly the rhythm or flow of communication.

Although the exact cause of stuttering is yet to be determined, genetics does play a role in stuttering, and a number of genetic variants having been identified to date.

The study involves 15 investigators at eight sites in Australia, the UK, the USA and The Netherlands. 

Study researchers are working to recruit 3,000 volunteers from Australia, aged 7+ with a history of stuttering (past or present).

Please see http://www.geneticavanstotteren.nl/ for more information about recruitment in the Netherlands and Belgium. We will be starting to recruit from other countries very soon - watch this space!

Participating in this study could make a genuine contribution to the understanding of stuttering.

How can you help?

If you currently live with, or have a history of stuttering, we encourage you to volunteer for our groundbreaking research study by completing the 10 minute core component of our online survey. Depending on your responses to our survey, you may be asked to donate a saliva sample.

To help us meet our target of 3,000 participants by 31 December 2020, volunteer for our study today
