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
