Objective: This study aimed to identify the clinical characteristics for differential diagnosis of Parkinson’s disease dementia (PDD) and dementia with Lewy bodies (DLB) by analyzing the differences in cognitive function and caregiver burden between the patient groups.
Methods: We conducted a retrospective cross-sectional study with idiopathic Parkinson’s disease patients and DLB patients.
Differences in cognitive function were measured using the standardized neuropsychological test battery (Seoul Neuropsychological Screening Battery-II). Differences in the caregiver burden were measured by the Neuropsychiatric Inventory-Questionnaire (NPIQ) for behavioral psychological symptoms of dementia (BPSD) and Korean-Instrumental Activities of Daily living (K-IADL) for daily living activities. For statistical analysis, chi-square test and multivariate analysis of variance and binary logistic regression and correlation analysis were conducted using SPSS 22.
Results: Nine Parkinson’s disease-Normal cognition (PD-NC), 25 Parkinson’s disease-mild cognitive impairment (PD-MCI), 20 PDD and 11 DLB patients were included. Compared with PDD and DLB, attentional deficit correlated more strongly with DLB, but language dysfunction showed more correlation with PDD. Caregiver burden correlated more strongly with DLB than PDD. Delusion and aberrant motor behaviors of NPI-Q and taking medicine of K-IADL were strongly related with the caregiver burden of both PDD and DLB.
Conclusion: This study identified that neuropsychological profile and caregiver burden in comparison of BPSD and ADL can contribute to the differential diagnosis of PDD and DLB.
