OBJECTIVE: This study explores the utility of the Mattis Dementia Rating Scale (MDRS) as a screening tool for the Diagnostic and Statistical Manual for Mental Disorders 4th edition (DSM-IV-TR) diagnosis cognitive disorder not otherwise specified (NOS) in Parkinson's disease (PD). METHODS: A total of 125 individuals with PD were diagnosed using DSM-IV-TR criteria for cognitive disorder NOS and dementia. Receiver operating characteristics (ROC) tested the discriminant validity of the MDRS, with the clinician's diagnosis serving as the gold standard. RESULTS: The MDRS ROC curve to discriminate subjects with cognitive disorder NOS from non-demented subjects had an area under the curve of 0.59 (standard error = 0.08, 95% CI: 0.43-0.74). CONCLUSIONS: The MDRS is not effective for identifying PD patients with cognitive disorder NOS without dementia.
