ABSTRACT

ABSTRACT The Consortium to Establish a Registry for Alzheimer's Disease (CERAD) neuropsychological battery was created to assess cognitive impairment in Alzheimer's disease (AD) but it is widely-used for various dementias. The aim of this study was to analyze the efficacy of using the CERAD battery in the assessment of patients with Parkinson's disease. Forty-nine patients with Parkinson's disease were divided into two groups (one with dementia and one without) using the Movement Disorder Society criteria for Parkinson's disease dementia. Cognitive deficits were assessed with the Clinical Dementia Rating Scale as the gold standard, and the CERAD. The ROC curve for the CERAD battery had an area under the curve = 0.989 (95% CI = 0.967 - 1, p<0.0001). Among the CERAD subtests, verbal fluency had the worst accuracy, and word list learning had the best accuracy. Despite the limits of this study, the CERAD battery can be efficient for assessment of cognitive deficits in Parkinson's disease patients.


RESUMO A Bateria Neuropsicológica do Consortium to Establish a Registry for Alzheimer's Disease (CERAD) foi criada para a avaliação da doença de Alzheimer (DA), mas é usada em várias demências. O objetivo deste estudo foi avaliar a efetividade dessa bateria na avaliação de pacientes com doença de Parkinson (DP). Foram avaliados 49 pacientes com DP sendo aplicadas CDR, como padrão-ouro e CERAD. Os pacientes foram divididos em dois grupos: com e sem demência, a partir dos critérios para DPP pela Movement Disorders Society. A curva ROC para o CERAD resultou em uma AUC=0.989 (95% CI = 0.967 - 1, p<0.0001). Entre os subtestes do CERAD, fluência verbal obteve a pior acurácia, e aprendizado de lista de palavras, a melhor. Apesar das limitações do estudo, a bateria do CERAD pode ser uma ferramenta eficaz na avaliação de déficits cognitivos em pacientes com DP

ABSTRACT

ABSTRACT Background: Screening tests have been used for cognitive deficits in Parkinson's disease (PD). Objective: This study compared the Montreal Cognitive Assessment (MoCA) test, the Mini-Mental State Examination (MMSE) and the clock drawing test for this purpose. Methods: A total of 50 patients with PD were selected, 41 (82%) were diagnosed with dementia by the criteria of the Movement Disorder Society. The test Scales for Outcomes in Parkinson's Disease-Cognition (SCOPA-Cog) was used as the gold standard in comparison with the screening tests. Results: The MoCA test (AUC=0.906) had a sensitivity of 87.80% and specificity of 88.89%. When the MMSE was associated with the clock drawing test (AUC=0.936), it had a specificity of 66.67% and sensitivity of up to 97.56%. Conclusion: The study suggests that the MoCA test can be a good screening test in PD. However, MMSE associated with the clock drawing test may be more effective than the MoCA test.


RESUMO Embasamento: Diversos testes têm sido utilizados como ferramenta de triagem para déficits cognitivos na doença de Parkinson (DP). Objetivo: Este estudo comparou os testes Montreal Cognitive Assessment (MoCA), Mini Exame do Estado Mental (MEEM) e teste do relógio para essa finalidade. Métodos: Foram selecionados 50 pacientes com DP, dos quais 41 (82 %) foram diagnosticados com demência pelos critérios da Movement Disorder Society. O teste Scales for Outcomes in Parkinson's Disease-Cognition (SCOPA-Cog) foi usado como padrão-ouro na comparação com os testes de triagem. Resultados: O teste MoCA (AUC=0,906) apresentou sensibilidade de 87,80% e especificidade de 88,89%. Quando o MEEM foi associado ao teste do relógio (AUC=0,936), apresentou especificidade de 66,67% e sensibilidade de até 97,56%. Conclusão: O estudo sugere que o teste MoCA pode ser um melhor teste de triagem na DP. Entretanto, o MEEM associado ao teste do relógio pode ser mais eficiente que o MoCA.

ABSTRACT

Tourette's syndrome (TS) is defined as a disorder characterized by multiple motor tics and at least one vocal tic that have lasted for not less than one year. It is a relatively complex neurobehavioral disorder, in which patients may present with coexistent attention deficit hyperactivity disorder, obsessive-compulsive disorder or other behavioral comorbidities. The musical genius Wolfgang Amadeus Mozart (1756-1791) and the rock star Kurt Cobain (1967-1994) may both have suffered from TS, and some contemporary musicians have had their clinical condition confirmed as TS. Our hypothetical diagnosis of TS in Mozart and Cobain is based on the presence of tics and psychiatric comorbidities. In contemporary musicians, such as Michael Wolff, Nick Van Bloss and James Durbin, TS has often only been diagnosed after a considerable delay. This delay in diagnosis and the controversies surrounding the clinical case of Mozart show how difficult a confirmatory diagnosis of this complex disease is.


A síndrome de Tourette (TS) é definida como uma desordem caracterizada por múltiplos tiques motores e pelo menos um tique vocal com duração de ao menos um ano. TS é um distúrbio neuro-comportamental relativamente complexo, em que os pacientes teriam coexistente transtorno de déficit de atenção e hiperatividade, transtorno obsessivo-compulsivo, distúrbio de comportamento ou outras co-morbidades. Talvez sejam casos de TS o do gênio musical Wolfgang Amadeus Mozart (1756-1791) e da estrela do rock, Kurt Cobain (1967-1994). Alguns músicos contemporâneos tiveram a sua condição clínica confirmada como TS. Em conclusão, os diagnósticos hipotéticos de TS nos casos de Mozart e Cobain podem ter embasamento na possibilidade de tiques e comorbidades psiquiátricas. Observou-se um atraso de diagnóstico de TS em músicos contemporâneos (Michael Wolff, Nick Van Bloss, James Durbin). Essa situação e as controvérsias sobre a clínica no caso de Mozart mostram a dificuldade para confirmação do diagnóstico dessa complexa doença.
