An acquired stuttering caused by neurological injury (e.g. stroke, traumatic brain injury), in which a person with no childhood stuttering history develops stutter-like dysfluencies following brain damage. Disfluencies in neurogenic stuttering can occur on any word position (content or function words) and show no significant adaptation effect (practice does not improve fluency), with minimal secondary behaviors, distinguishing it from developmental stuttering.
