title: Definite malingered neurocognitive dysfunction in moderate/severe traumatic brain injury.
abstract: There has been disagreement in the literature about whether persons with documented neuropathology can be diagnosed as malingering. To address this question, we present three moderate severe traumatic brain injury patients who were evaluated in the context of litigation who met the Slick, Sherman, and Iverson (1999) criteria for a diagnosis of "Definite Malingered Neurocognitive Dysfunction." Each performed significantly below-chance on at least one forced-choice symptom validity test, thereby demonstrating a deliberate attempt to appear impaired. These cases represent the first definitive evidence of an intentional effort to appear impaired in the context of documented moderate/severe traumatic brain injury.
