Cognitive decline in Parkinson's disease: contributions of Neuropsychology

To evaluate the prevalence of cognitive decline in Parkinson’s disease (PD) and the contributions of Neuropsychology to its diagnosis and treatment. Objectives: to emphasize the importance of a neuropsychological assessment as a strategy for research and early diagnosis of cognitive and behavioral disorders associated with PD in addition to the role of cognitive rehabilitation in the treatment of these patients. Methodology: a bibliographic survey of articles in Pubmed, Medline, Lilacs, and Scielo published over the past 10 years. Conclusions: the cognitive alterations observed in PD are related to memory, language, visual-spatial capacity, and executive functions; however, there is a lack of information regarding the cognitive rehabilitation of these patients.
