Part 1: What’s new in stuttering research

Treating young children who stutter: Indirect or direct?

A recent study¹ used a randomized control trial (highest level of evidence), to determine the effectiveness of Lidcombe vs. RESTART-DCM for treating preschool children who stutter. The researchers found that at 18 months, clinical outcomes for direct and indirect treatment were comparable. The authors conclude that both treatments are equally effective in treating developmental stuttering in ways that surpass expectations of natural recovery.

• The genes identified in stuttering all point to a single process, intracellular trafficking, but only account for at most 20% of persistent stuttering cases³.
• Bottom line: Stuttering is genetic, but this isn’t the whole picture.

What is happening when you are stuttering? Do you know what you want to say? What should I do when this happens?” my friend anxiously asked.

With her voice cracking and her eyes diverting from mine, I could tell that these were hard questions for my friend to ask. I smiled, and thanked her for asking. These were really good questions.
