STUTTERING

This study tests whether a safe, noninvasive brain stimulation technique called HD-tDCS can reduce stuttering symptoms like repetitions and blocks. Fifty adults who stutter will receive a single session of stimulation and complete speaking tasks before and after. The goal is to s…

This study tests whether a gentle brain stimulation technique (tDCS) combined with standard speech therapy can reduce stuttering severity and its negative impact on daily life. Sixteen adults who stutter will receive both treatments, and researchers will measure changes in speech…

This study uses brain scans (fMRI) to compare brain activity when adults who stutter produce stuttered versus non-stuttered speech. Researchers aim to understand which brain circuits are involved. Fifty adults aged 18-65 who stutter will participate. This is not a treatment study…

This study follows 120 children aged 3-6 who stutter or have typical speech, to learn why some recover naturally. Kids complete speech tests, wear brain-monitoring caps, and speak in virtual reality classrooms. Researchers track brain activity, heart rate, and skin responses to f…

This study looks at how children who stutter perform on rhythm tasks compared to children who don't stutter. Researchers will test rhythm perception and production once a year for three years in 500 children. The goal is to understand how rhythm skills might be linked to brain ac…
