ABSTRACT
A commonly asked question is: “Is there something different in the brain that makes people stutter?” There is evidence from a good many sources that links stuttering to neurological anomalies. Some people who stutter may be differentiated from those who do not by lateralization of language function. There may be biochemical factors which distinguish the two groups, and stuttering may be triggered by drugs acting on the central nervous system (CNS). Subcortical processing of linguistic information may be different, and stuttering has been linked to the function of subcortical structures.
