Abstract


OBJECTIVE
The differences of various neurocognitive functions, including attention, memory, motor function, and higher cognitive function were compared between PTSD patients and normal control subjects. Also, correlation with PTSD symptom severity and neurocognitive functions were evaluated between PTSD patients and normal control subjects. METHOD: We assessed the neurocognitive functions by computerized neurocognitive test(CNT) batteries. The visual continuous performance test(CPT) and digit span test, finger tapping test and Wisconsin card sorting test(WCST) were executed. The Impact of Event Scale-Revised(IES-R) was used in the evaluation of the severity of PTSD. RESULT: The PTSD patients showed significantly impaired neurocognitive performance in all of the items, compared with normal control subjects. The relation between impairment in neurocognitive functions and symptom severity showed significant correlations.
CONCLUSION
These results imply that PTSD patients have impaired neurocognitive functions concerning with specific brain areas, especially the frontal area. For the thorough evaluation of further neurocognitive functions, more detailed evaluation items of neurocognitive functions and brain imaging studies are necessary in the future study.
