Neurological basis of stuttering

Stuttering is a neurodevelopmental speech disorder of complex aetiology. Although we are continually learning about the causes of stuttering, there is insufficient research and evidence regarding the neurological basis of stuttering. It can be said with certainty that there are structural and functional differences between the brains of people who stutter and those who do not stutter, and these differences are present in the cortical and subcortical areas of the brain. This review paper provides an overview of the existing knowledge on the neurological basis of stuttering by examining theoretical frameworks with regard to the structural foundations of stuttering and its scientific basis. In addition, this paper provides insight into future research and, accordingly, possible new theoretical frameworks.
