RESUMO
ABSTRACT BACKGROUND AND OBJECTIVES: The purpose of this study was to evaluate the presence of cognitive deficits in patients with episodic migraine and control group, and to compare with the results previously described in the literature. METHODS: Patients with episodic migraine were included according to the International Headache Society criteria, and a control group was selected, matched by sex, age, and schooling. Patients were asked about the frequency and intensity of headaches, medications used, and comorbidities. Afterwards, a neuropsychological assessment was applied using the Montreal Cognitive Assessment, the clock drawing test, the verbal fluency test, and the Stroop test. The main variables influencing cognitive dysfunctions were analyzed (depressive disorder, anxiety disorder, sleep disorder, use of medication). RESULTS: Thirty patients with episodic migraine and 30 controls were evaluated. Patients with episodic migraine had a performance in the Montreal Cognitive Assessment test (p=0.53), the clock drawing test (p=0.80), the verbal fluency test (p=0.44) and the Stroop test (p=0.97) similar to the control group. Patients with chronic migraine (30 patients and 30 controls) performed a Montreal Cognitive Assessment test (p=0.00), verbal fluency test (p=0.00) and Stroop test (p=0.00) lower than the group control. The main variables influencing cognitive disorders were studied by linear regression, and none of these variables was an influencing factor in the Montreal Cognitive Assessment test. CONCLUSION: Patients with episodic migraine did not present cognitive deficits compared to a control group.
RESUMO JUSTIFICATIVA E OBJETIVOS: A proposta deste estudo foi avaliar a presença de déficits cognitivos em pacientes com migrânea episódica e grupo controle, e comparar com os resultados previamente descritos na literatura. MÉTODOS: Foram incluídos pacientes com migrânea episódica, segundo os critérios da International Headache Society, e selecionado um grupo controle pareado por sexo, idade e escolaridade. Os pacientes foram questionados sobre a frequência e intensidade de crises, fármacos, comorbidades. Posteriormente, foi realizada a avaliação neuropsicológica através do Montreal Cognitive Assessment, do teste do relógio, teste da fluência verbal e Stroop teste. As principais variáveis influenciadoras de distúrbios cognitivos foram analisadas (transtorno depressivo, transtorno de ansiedade, distúrbios do sono, uso de fármacos). RESULTADOS: Foram avaliados 30 pacientes com migrânea episódica e 30 controles. Os pacientes com migrânea episódica apresentaram uma performance no Montreal Cognitive Assessment teste (p=0,53), teste do relógio (p=0,80), teste da fluência verbal (p=0,44) e Stroop teste (p=0,97) semelhante ao grupo controle. Pacientes com enxaqueca crônica (30 pacientes e 30 controles) realizaram um teste de Montreal Cognitive Assessment teste (p=0,00), teste de fluência verbal (p=0,00) e teste de Stroop (p=0,00) menor que o grupo controle. As principais variáveis influenciadoras de distúrbios cognitivos foram estudadas através de regressão linear e nenhuma dessas variáveis apresentou-se como fator de influência no Montreal Cognitive Assessment. CONCLUSÃO: Os pacientes com migrânea episódica não apresentaram déficits cognitivos em comparação com um grupo controle.
RESUMO
Objective To describe and analyze cognitive aspects in patients with chronic pain and a control group without pain. Method A case-control study was conducted on 45 patients with chronic pain and on 45 control subjects. Data including pain diagnosis, comorbidities and medication used, were evaluated. Cognitive tests, such as the Montreal Cognitive Assessment (MoCA), Verbal Fluency Test, Clock Drawing Test and Stroop Test, were applied. Results Patients with chronic pain showed a poorer performance, as shown by the scores of the MoCA test (p < 0.002), Verbal Fluency Test (p < 0.001), Clock Drawing Test (p = 0.022) and Stroop Test (p < 0.000). Chronic pain variable (p = 0.015, linear regression model) was an independent factor for results obtained with the MoCA. Conclusion Patients with chronic pain showed a poorer performance in a brief screening test for cognitive impairment not related to confounding variables, as comorbidities and pain-medication use.

RESUMO Objetivo Descrever e analisar aspectos cognitivos em pacientes com dor crônica e um grupo controle sem dor. Método Um estudo de caso-controle foi conduzido em 45 pacientes com dor crônica e 45 controles. Dados incluindo diagnóstico da dor, comorbidades e medicações utilizadas foram avaliados. Foram aplicados testes cognitivos, tais comoMontreal Cognitive Assessment, Teste da Fluência verbal, Teste do relógio e Teste de Stroop. Resultados Pacientes com dor crônica apresentaram uma pior performance, em scores do MoCA (p < 0.002), Fluência verbal (p < 0.001), Teste do relógio (p = 0.022) e Stroop (p < 0.000). Dor crônica (p = 0.015, modelo de regressão linear) foi um fator independente para os piores resultados obtidos no MoCA. Conclusão Pacientes com dor crônica apresentaram uma pior performance em uma avaliação breve para comprometimento cognitivo, não relacionada a variáveis confundidoras, como comorbidades e medicações utilizadas para dor.
