Cognitive profile in PD

<p>The Project was designed to analyze the cognitive heterogeneity in PD patients using a novel data driven approach, the Latent Profile Analysis (LPA), to classify patients according to cognitive characteristics. </p>

<p>This dataset include information about general and specific cognitive perfomance in 71 PD patients without dementia. The neuropsychological battery included different memory and executive function tests. Memory was assessed both for semantic and episodic capabilities. Semantic memory was assessed with a Semantic fluency task (SF; Benton and Hamsher, 1978) and the Boston Naming Test (BNT; Kaplan and Weintraub, 1983). Episodic memory was assessed both with verbal and visuospatial material. Verbal episodic memory was assessed using the Spain-Complutense Verbal Learning Test (Test de Aprendizaje Verbal España-Complutense, TAVEC; Benedet and Alexandre, 1998), and visuospatial episodic memory was assessed using the 7/24 Spatial Recall Test (7/24 SRT; Rao, Hammeke, McQuillen, Khatri, and Lloyd, 1984). Executive function was assessed using the Phonemic Fluency Task (PF; Benton and Hamsher, 1978), the Backward Digit Span of the WAIS-III (BDS; Weschler, 2001) and the Trail Making Test (TMT; Reynolds, 2002). They were selected following the recommendation for neuropsychological evaluation of PD made by the Movement Disorder Society Task Force Guidelines (Litvan et al., 2012).</p>
