Impairment of visuospatial memory in stages 2 and 3 of Parkinson's disease

Objective: Parkinson's disease is not only related to motor difficulties but also to cognitive impairmet. Hence, it is worth knowing if the cognitive functions related to visuospatial information are affected as the severity of the disease increases. Method: This study intends to establish differences according to the Parkinson's disease stage from evaluation and analysis of visuospatial information in 27 patients using the Complex figure of Rey-Osterrieth test. Results: The results show significant differences in the visuospatial memory between both groups, which could indicates that the evolution of the disease seems to determine the severity of the cognitive alteration, mainly with regard to visuospatial memory. Conclusion: The results suggest to incorporate visuospatial information in speech-language evaluations of Parkinson's disease patients in order to design therapeutic plans focused on the neuropsychological deficit.
