   Proposal Description:
   The purpose of this study is to review the sensitivity and specificity of the  Clinical Dementia Rating Scale (CDR) for detecting dementia in Parkinson???s  disease patients. The CDR was developed to detect Alzheimer???s disease (AD)  many of the core symptoms of Parkinson???s disease Dementia (PDD) and AD are  different, therefore there may be differences in the optimal cutoff scores for  PDD and AD. Previous researchers have used the CDR in staging dementia in  participants with PDD, however there is no research to date examining if the  published CDR cutoff scores are appropriate for patients with Parkinson???s  disease. Participants are classified into three diagnostic categories:  non-demented, mild cognitive impairment, and dementia. These diagnostic  categories will be used to calculate the sensitivity and specificity of the  CDR-global score and CDR-sum of boxes in detecting cognitive impairment in  patients with Parkinson???s disease. The data will be used to complete a  dissertation project.
