Disfluency in Tourette syndrome: observational study in three cases.

It is often stated that stuttering is a common speech disorder in individuals with Tourette syndrome (TS). It has also been suggested, however, that the fluency failures observed in people with TS do not completely conform to the classic pattern of stuttering. The present paper describes the results of an analysis of the speech patterns of three individuals with TS. A picture emerged that bears some resemblance to stuttering, cluttering, and palilalia but that is also different from each of these disfluency types. Copyright 2004 S. Karger AG, Basel.
