Thank you! Yes I agree, according to [this](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8802677/) research study, neurogenic stuttering is characterized by disfluencies associated with acquired brain damage.

What is neurological in stuttering? ||Neurological causes of stuttering|Neurological effects of stuttering| |:-|:-|:-| |1.||| |2.||| |3.||| |4.||| |5.|||
