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.
现呈现三则案例，这些案例中的特殊言语和语言异常是在个人伤害诉讼或轻度创伤性脑损伤后脑功能障碍的工人赔偿要求的背景下进行评估的。神经心理学的努力和动机测量显示出动机不足或彻头彻尾的装病的证据。这些案例的言语和语言异常可能与口吃或失语等神经源性言语不流畅特征不一致。我们提出，在单次、简单、轻度创伤性脑损伤后持续存在严重的不流畅或语言异常是不常见的，应该引起对心因性起源的怀疑。
