abstract="The purpose of this study was to investigate possible neuropsychological differences in Halstead-Reitan characteristics between motor vehicle accident litigants and insurance claimants that sustained uncomplicated mild traumatic brain injury (mTBI) and did or did not sustain direct impact to the head (i.e., Impact vs. Nonimpact mTBI), and to compare these clinical groups with a control group that did not suffer mTBI (No mTBI). The Tactile Form Recognition Test (TFR) was the only level of performance test in the Halstead-Reitan Battery (HRB) that generated statistically significant differences. The TFR resembles a complex reaction time test. TFR response time was significantly longer for Nonimpact mTBI patients than for Impact mTBI and No mTBI participants. Frequency comparisons of abnormal score patterns demonstrated that Nonimpact patients produced significantly more aberrant Impairment Index vs. FSIQ score patterns than Impact and No mTBI participants. Given the components of the score pattern, this finding suggests that Nonimpact patients may experience less recovery from neuropsychological deficits than Impact participants. Complex perceptual reaction times and score patterns comparing sensitive and &quot;hold&quot; test results may represent heuristic avenues of future research in the study of compensation-seeking Nonimpact and Impact mTBI patients.<p /> <p>Language: en</p>",
