After centuries of misunderstanding, researchers are tying the condition to genes and brain alterations.
Speech-language pathologist and neuroscientist Soo-Eun Chang of the University of Michigan, has been trying to understand why about 80 percent of kids who stutter grow up to have normal speech patterns, while the other 20 percent continue to stutter into adulthood. Stuttering typically begins when children first start stringing words together into simple sentences, around age 2. Chang studies children for up to four years, starting as early as possible, looking for changing patterns in brain scans.
