Stuttering is a neurological condition affecting up to 10% of children and 1% of adults New research may have pinpointed the disrupted brain network behind stuttering This network appeared to play a role regardless of whether the stutter was developmental or triggered by a stroke THURSDAY, May 30, 2024 (HealthDay News) -- Stuttering is a neurological condition, not a psychological one, and scientists in Finland now believe they've found the disrupted network in the brain that may cause it. "These findings explain well-known features of stuttering, such as the motor difficulties in speech production and the significant variability in stuttering severity across emotional states," said senior study author , a professor of neurology at the University of Turku. His team published its findings May 27 in the journal .
According to the researchers, anywhere from 5% to 10% of children will develop a stutter, and 1% of adults also struggle with stuttering. President Joe Biden has been open about his lifelong management of his own stuttering. “Stuttering was once considered a psychological disorder," Jpoutsa said in a university news release.
"However, with further research, it is now understood to be a brain disorder related to the regulation of speech production." But just where in the brain a person's stutter might originate has been unknown. In the study, Joutsa's group first focused on 20 adults (ranging in age from 45 to 87) who all developed a stutter after suffering a .
