Domestic violence in Lewy body dementia: A national study.

A descriptive study using a transversal national online survey to evaluate the prevalence and characteristics of behavioral and psychological symptoms (BPSD) of dementia with Lewy bodies (DLB), and specifically, the perpetration of violent acts against primary caregivers. 196 responses, obtained in one month, were analyzed. Delirium, hallucinations, anxiety, and apathy were the most frequently reported BPSD symptoms (over 80% of responders). Primary caregivers expressed the highest degree of distress from agitation and aggressive behavior. Moreover, 45.9% of primary caregivers reported being the target of violent behaviors from DLB patients. No statistical association was found between the presence of BPSD and violent acts.
