Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study tests whether education about memory and pain might help to prevent aggression in persons with dementia who have pain. The overall goal of this intervention is to reduce the risk of aggressive behavior by improving several areas of patient life that are known causes of aggression: pain, depression, lack of pleasurable activities, caregiver stress and difficulty in caregiver-patient communication.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Arm 1: PAVeD Intervention

In the experimental arm, the caregiver will receive six to eight 45-minute visits to teach caregiver about pain and memory problems. The person with dementia will also be able to learn from these visits. These visits will take place over three months.

Group Type EXPERIMENTAL

PAVeD Intervention

Intervention Type BEHAVIORAL

In the PAVeD Intervention, the caregiver will receive six to eight 45-minute visits to teach caregiver about pain and memory problems. The person with dementia will also be able to learn from these visits. These visits will take place over three months.

Arm 2: Enhanced Usual Care

In the comparison arm, the caregiver will receive information in the mail about memory problems and pain; and the caregiver will receive eight short telephone calls to check on how the person with dementia is doing.

Group Type ACTIVE_COMPARATOR

Enhanced Usual Care

Intervention Type BEHAVIORAL

In Enhanced Usual Care, the caregiver will receive information in the mail about memory problems and pain; and the caregiver will receive eight short telephone calls to check on how the person with dementia is doing.

Primary Care providers will be notified through electronic medical records about any significant behavioral problems or pain.

* reside outside a long-term care facility
* live within 45 minutes of the MEDVAMC
* have mild-to-moderate dementia
* have no history of aggression in the past year
* have no evidence of aggression on the CMAI at baseline (i.e., do not score 2 or higher on both frequency and disruptiveness for any of 13 behaviors listed).
* have a caregiver who is directly involved with the patient:

* at least 8 hours per week
* sees the patient at least twice a week
* and speaks English
* report clinically significant pain (either directly or through the caregiver as a proxy)

Exclusion Criteria

Patients will be excluded if they have had history of aggression in the past year
