- Abstract: BACKGROUND: Complex regional pain syndrome (CRPS) is characterized by severe neuropathic pain and disability, which can result in psychological and behavioral dysfunction. The goal of the present study was to evaluate neurocognitive disability, and to assess the relationship between clinical variables and neuropsychological features in CRPS patients. METHODS: We investigated the neuropsychological features of 15 CRPS I patients. The neuropsychological tests that we made comprised of a full intelligence quotient, memory quotient, trail-making test A, trail-making test B (TMT-B), and MMPI (Minnesota multiphasic personality inventory). RESULTS: The results showed severe disability in performance on TMT-B. There was no significant correlation between specific cognitive variables and MMPI scales. CONCLUSIONS: Decreased performance on TMT-B which shows mental flexibility in the prefrontal lobe exists independently from depressive disorders in CRPS patients.
