 Dementia is known primarily for its effects on memory, however, eighty percent of persons with dementia also have behavioral disturbances. This is often not addressed, leading to increased use of nursing homes, higher incidence of injury both patient and caregiver and the use of tranquilizing medications. Pain is one of the strongest predictors of aggression. The prevalence of pain in persons with dementia is known to be about 50. Untreated pain is associated with significant negative outcomes, including increased health care use, inactivity and isolation. The investigators aim to determine whether outcome differences exist between active intervention and control conditions in relation to the occurrence of aggressive behavior, pain and depression, and its impact on pleasant activities, caregiver burden, quality of caregiver-patient relationship, antipsychotic use, health-service use, injuries to patient and caregiver, and nursing home placement. The active intervention, Preventing Aggression in Veterans with Dementia PAVeD, is a family caregiver-focused, home-based intervention that uses psychoeducational and behavioral approaches to help reduce the risk of aggressive behavior in persons with dementia. The objective of PAVeD is to improve several areas of patient life that are known causes of aggression: pain and distress including mood problems, lack of pleasurable activities, and difficulty in patient-caregiver communication that may negatively affect relationship quality and caregivers recognition of pain.
