Depressive symptoms and sensory dysfunction, such as reduction in visual olfactory function, are common Parkinson's disease (PD). Previous studies have suggested that depressive associated with impairments potentially hyposmia several types of mood disorders. However, the relationship between dysfunction remains unclear PD. To examine association color vision function PD, authors conducted a cross-sectional study 159 patients were measured Beck Depression Inventory-II (BDI-II) 30-item Geriatric Scale (GDS-30); was tested Farnsworth-Munsell 100 Hue Test (FMT); Sniffin' Sticks Screening 12 Test. Results showed total error score (TES) for FMT significantly independently correlated scores on both BDI-II GDS-30 positive manner, suggesting more severe poorer In addition, somatic effective subscores TES FMT, while no significant correlation observed or GDS-30. The decrease but not found to be severity PD patients, supporting idea occurrence is linked disruption system.
