ABSTRACT
OBJECTIVE: To compare patients with posttraumatic stress disorder (PTSD) to patients without psychiatric or cognitive disorders on neuropsychological measures of attention. METHODS: The sample included 19 patients with PTSD and 22 participants with no cognitive or psychiatric diagnosis. All had been referred for clinical neuropsychological evaluation at a VA Medical Center. None were diagnosed with dementia, delirium, or current substance dependence except nicotine or caffeine, and none had a history of stroke or of traumatic brain injury with loss of consciousness. Patients were excluded if they failed to exert adequate effort on testing. RESULTS: PTSD patients performed significantly more poorly than patients without psychiatric diagnoses on Digit Span. CONCLUSION: PTSD patients were impaired relative to participants without psychiatric diagnoses on a measure of focused attention. Several factors, including the small sample size, suggest that the results should be considered preliminary.
