Study design and methods: U.S. study to protect brain health through lifestyle intervention to reduce risk (U.S. POINTER).

INTRODUCTION: The U.S. study to protect brain health through lifestyle intervention to reduce risk (U.S. POINTER) is conducted to confirm and expand the results of the Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER) in Americans. METHODS: U.S. POINTER was planned as a 2-year randomized controlled trial of two lifestyle interventions in 2000 older adults at risk for dementia due to well-established factors. The primary outcome is a global cognition composite that permits harmonization with FINGER. RESULTS: U.S. POINTER is centrally coordinated and conducted at five clinical sites (ClinicalTrials.gov: NCT03688126). Outcomes assessments are completed at baseline and every 6 months. Both interventions focus on exercise, diet, cognitive/social stimulation, and cardiovascular health, but differ in intensity and accountability. The study partners with a worldwide network of similar trials for harmonization of methods and data sharing. DISCUSSION: U.S. POINTER is testing a potentially sustainable intervention to support brain health and Alzheimer's prevention for Americans. Impact is strengthened by the targeted participant diversity and expanded scientific scope through ancillary studies.

A Systematic Review of Tools Assessing the Perspective of Caregivers of Residents With Dementia.

In collaboration with stakeholders, we conducted a systematic review of psychometric evidence for self-report tools measuring the perspective of family caregivers of nursing home residents with dementia. Our rationale for this review was based on evidence that nonpharmacological interventions can ameliorate dementia symptoms in nursing home residents. Such interventions require caregiver participation, which is influenced by perspectives. Yet, no existing tool measures the multidomain caregiver perspective. Our review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol. The final sample included 42 articles describing 33 tools measuring domains of nursing home dementia care such as behavioral and psychological symptoms of dementia, resident quality of life, dementia-specific knowledge, communication, and medication use. We uncovered evidence gaps for tools measuring dementia-specific knowledge, communication, and medication use, all of which were important to our stakeholders. Future research should focus on development of psychometrically sound tools in alignment with the multidomain caregiver perspective.
