Stuttering as a matter of delay in neural activation: a combined TMS/EEG study

Developmental stuttering (DS) is a disturbance of the normal rhythm of speech that usually appears in childhood, where affected persons know what they intend to say, but are not able to do it fluently. DS is characterized by dysfluencies such as blocks and repetitions, often associated with movements, especially of the oro-facial district. The majority of DS children are able to recover to normal levels, while others remain stutterers into adulthood (persistent DS). DS is related to abnormalities of the central nervous system (Brown et al., 2005; Neef et al., 2015a), and can be considered as a neuro-developmental disorder where speech is mostly affected, considering that it relies on motor skills for planning/execution of articulation (Smith and Weber, 2017).
