The aim of this study was to relate these dysfunctions with measures of brain. The sample of this study consisted of 92 PD patients and 36 healthy subjects matched by age, sex and education. All subjects were evaluated with Judgment of Line Orientation, Visual Form Discrimination and Facial Recog- nition Tests and magnetic resonance imaging at 3 Tesla. We found significant differences between patients and controls in all three tests and in the mean of cortical thickness, gray matter volume and ventricular system. All visuospatial and visuoperceptual tests correlated with the measures of global atrophy sug- gesting that they are reflecting the brain degeneration associated to PD. 2013 artículo científico 0066-5126 https://www.redalyc.org/articulo.oa?id=97029454001 en http://www.redalyc.org/revista.oa?id=970 Anuario de Psicología application/pdf Universitat de Barcelona Anuario de Psicología (España) Num.2 Vol.43 |
