Psychogenic stuttering and other acquired nonorganic speech and language abnormalities

Abstract

Three cases are presented of peculiar speech and language abnormalities that were evaluated in the context of personal injury lawsuit or workers compensation claims of brain dysfunction after mild traumatic brain injuries. Neuropsychological measures of effort and motivation showed evidence of suboptimal motivation or outright malingering. The speech and language abnormalities of these cases probably were not consistent with neurogenic features of dysfluent speech including stuttering or aphasia. We propose that severe dysfluency or language abnormalities persisting after a single, uncomplicated, mild traumatic brain injury are unusual and should elicit suspicion of a psychogenic origin. © The Author 2012.
