Objective: This study aimed to build on past research (e.g., Pedersen, Larsen, Alves, & Aarsland, 2009) that has demonstrated a clear negative association between cognition and apathy in individuals with Parkinson's Disease (PD). We predict a moderate negative correlation between apathy measured by the Apathy Scale (AS; Starkstein, et al., 1992) and cognition measured by the Dementia Rating Scale-2 (DRS-2; Jurica, Leitten, & Mattis, 2001). Method: This study will follow a correlational design. 339 participants (117 women) were included in this study. Participants were selected as long as they met the criterion of being diagnosed with PD. All participants came from a PD Interdisciplinary Clinic at a Midwestern Academic Medical Center. Each participant was administered the AS and the DRS-2. The primary study variables included the total sum of the AS and the DRS-2 Age- and Education-Corrected MOANS [Mayo's Older Americans Normative Studies] Score (AEMSS). Results: The results of the study indicate a positive correlation between the sum of the AS and the DRS-2 AEMSS (r = .32), although this was statistically non-significant (p = .68). Conclusion: Results from this study indicate there is a trend for patients with PD that have more intact cognition to have higher levels of apathy. Implications from these results, including how a person's awareness of changes due to PD may lead to an increase in apathy, will be further discussed.
