RESUMO

Objectives: to assess attention and memory of patients who are chronic pelvic pain holders (CPP) and/or Complex Regional Pain Syndrome (CRPS) holders, and to correlate the results to the characteristics of the duration and intensity of the pain, and to the mood and to the sleep pattern disorders, by comparing such results to the control group of pain-free individuals. Methods: 35% male and 65% female individuals, 18 to 60 years old, with schooling higher or equal to four years, were evaluated through a series of neuropsychological tests directed to assess the attention and memory, pain intensity, mood, and sleep quality. They were organized in three groups: 20 Pelvic Pain Patients (CPP Group); 20 Complex Regional Pain Syndrome patients (CRPS Group); 20 pain-free individuals (Control Group). Results: there was prevalence of 29 to 50 year-old individuals with regular and formal professional activity and schooling of 9 to12 years. Most of them presented moderate to severe pain during the last 6 to 15 years (none of them during less than five years). Pain patients presented lower quality sleep than individuals pain free (p <0, 001), more Major Depression Disorder assessed by PRIME-MD (p = 0, 013) and more changes in MEEM (p = 0, 001). There was more Verbal Fluency Deficit (p = 0,031), average Attention (p = 0,027) and lower scores in RAVLT test in CPP and CRPS groups than in non-pain individuals. The scores in the tests of Verbal Fluency, DSI and Attention were lower in patients with moderate to severe pain. Major Depression Disorder was related to Verbal Fluency, Attention and Memory impairment. The cognitive tests were significantly different in individuals with low-quality sleep than in the normal population. Conclusion: Pain patients showed greater deficit in the MEEM, Verbal Fluency Test, RAVLT, and in the Attention Test, and also Major Depression Disorder and lower quality of sleep when compared to the non-pain individuals. The Verbal Fluency, DSI and Attention scores were lower in patients with moderate to severe pain. Major Depression Disorder seems to interfere with Verbal Fluency, Attention and Memory. The cognitive function evaluated with DSD, DSI, Concentrated Attention, Verbal Fluency and MEEM tests score lower in individuals with low-quality sleep, and the difference was statistically significant to the normal population
