Background: Unresolved pain is related to neuropsychiatric symptoms (NPS) in persons living with dementia (PLWD), and an increase in NPS is distressing for PLWD and their caregivers. Hence, we examined whether pain in PLWD was related to caregiver burden and whether caregiver upset with NPS mediated this relationship. Methods: We examined, cross-sectionally, the relationships among pain in PLWD, caregiver burden, and upset with NPS.
