Determinants of behavioral and psychological symptoms of dementia: A scoping review of the evidence.

BACKGROUND: Behavioral and psychological symptoms of dementia (BPSD) are prevalent in people with neurodegenerative diseases. PURPOSE: In this scoping review the Kales, Gitlin and Lykestos framework is used to answer the question: What high quality evidence exists for the patient, caregiver and environmental determinants of five specific BPSD: aggression, agitation, apathy, depression and psychosis? METHOD: An a priori review protocol was developed; 692 of 6013 articles retrieved in the search were deemed eligible for review. Gough's Weight of Evidence Framework and the Cochrane Collaboration's tool for assessing risk of bias were used. The findings from 56 high quality/low bias articles are summarized. DISCUSSION: Each symptom had its own set of determinants, but many were common across several symptoms: neurodegeneration, type of dementia, severity of cognitive impairments, and declining functional abilities, and to a lesser extent, caregiver burden and communication. CONCLUSION: Research and policy implications are relevant to the National Plan to Address Alzheimer's Disease.

Evidence-based Non-pharmacologic Interventions for Managing Neuropsychiatric Symptoms and Mental Health Issues in Residents in Assisted Living.

THE PROBLEM: Mental health issues such as depression and neuropsychiatric symptoms (NPS) (e.g. agitation, aggression, rejection of care, wandering) are prevalent among residents in Assisted Living Facilities (ALF). Historically, these issues have only been treated with medications that can have a high risk of adverse effects in this population. This paper presents a scoping review of nonpharmacological interventions tested in ALFs for two of the most prevalent mental health issues: depression and NPS. KEY FINDINGS: Thirteen studies met inclusion criteria. Of those, eight (61.5%) found positive outcomes. Activity based and music therapy that utilize customization to interests and abilities showed the most promise. TIPS FOR SUCCESS: Based on findings we offer five recommendations: 1) adopt evidence-based or evidence-informed interventions; 2) use tailored activity as a therapeutic modality; 3) adopt new training approaches for staff; 4) use emerging technologies for training and intervention; and 5) participate in practice based research.
