Filmmakers, researchers have made incredible advances in understanding stuttering—a potentially debilitating speech disorder that disrupts the flow of communication that affects more than 400 million people worldwide. Developmental stuttering is the most prevalent fluency disorder. It impacts five to eight percent individuals globally across their lifespan. Australia has the highest reported prevalence rate of stuttering, with as many as 11% of its population disfluent.
In a groundbreaking study published today, researchers from five countries performed the largest genetic analysis of stuttering to date. In their study, they pinpointed 48 genes and 57 genomic hotspots associated with the disorder. This most recent study uncovers important genetic connections between stuttering and other forms of neurodiversity, emotional regulation and musical rhythm. This research not only sheds light on the biological basis of stuttering, it paves a way toward earlier intervention.
The implications of this research are profound. Scientists are working to find the genetic markers associated with stuttering. Armed with this knowledge, clinicians may be better able to identify which family members are at risk of developing the disorder. Harriet Hewitt, 10, conjures up the character of Clarissa and the world she inhabits. Her father and grandfather both stuttered, which makes her the fourth generation in her family to deal with the disorder. Her story is a reminder of the personal cost caused by stuttering and the need for better therapies.
The Curtin Stuttering Treatment Clinic in Western Australia plays a pivotal role in addressing the needs of those with stuttering and fluency disorders. The clinic has become a robust, multidisciplinary practice, treating infants to seniors. One of America’s top cancer research centers, it has gained an international reputation for its innovative research into new treatment approaches. This unique combination of clinical expertise and research can bring value and innovation to its quality of care for patients and their families.
Through large-scale genetic studies, researchers are beginning to untangle the intricate web of stuttering. This progress has brought increasing hope to the millions living with the disease. The connections between genetics and stuttering hold thrilling potential. This knowledge may lead to tailored interventions, enabling people to speak in a manner they’re more comfortable with.
