Prediction of cognitive impairment in PD by MoCA

The aim of this project is to analyze the capacity of the MoCA to detect cognitive impairment in PD, and also to identify anterior and posterior profiles defined by the dual síndrome hypothesis This dataset include information 59 patients with idiopathic PD were studied with the MoCA and a neuropsychological battery of tests covering all cognitive domains. Tests were selected according to the recommendations of the MDS to assess cognitive impairment in PD patients (Litvan et at., 2012).

More specifically, the following processes were assessed: attention/working memory, memory, visuospatial abilities, language and executive functions. Both the MoCA subtests and the neuropsychological tests were grouped according to the two profiles defined by the dual syndrome hypothesis. Hence, a profile was defined for Anterior/attention-executive función and another for Posterior/Memory-Visuospatial impairment.
