Objectives
Narrative objectives1
The objective is to conduct research related to the treatment needs of DLB patients and their caregivers, as well as physicians' understanding of those treatment needs. Then, the researchers will identify discrepancies in treatment needs between physician and patients/caregivers. In the event of a discrepancy, the researchers will analyze the cause. In addition, the researchers will gain an understanding of the differences in focus and treatment priorities for DLB symptoms among physicians and clinical departments and analyze the factors that contribute to such differences.
