Barriers and Facilitators of Health and Well-Being in Informal Caregivers of Dementia Patients: A Qualitative Study.

BACKGROUND: Given the dramatic projected increase in Alzheimer's disease globally and the increased risk of morbidity and mortality for family caregivers of these patients, there is an urgent need to provide more targeted, timely resources to support the health and well-being of these informal caregivers. Few studies have investigated the barriers to health and well-being and potential strategies to facilitate better self-care from the unique perspective of the caregivers themselves. PURPOSE: This qualitative study aimed to identify barriers and facilitators to health and well-being for informal caregivers of family members with Alzheimer's. METHOD: We conducted semi-structured interviews with eight informal caregivers, including daughters, wives, and one husband, ages 32 to 83. Using Reflexive Thematic Analysis, we identified three main themes and subthemes across caregivers' experiences. FINDINGS: We found that caregivers (1) prioritized mental and social well-being over physical health or health behaviors; (2) characterized the subjective burden of caregiving as a "mantle of responsibility" that could not easily be shed due to the complex subjective burden of loss, grief, guilt, resentment, isolation, loneliness, and lack of agency; (3) sought to be recognized as "additional patients", instead of being viewed as invisible patients, with support services tailored to their life stage and challenges. CONCLUSIONS: The findings suggest that the subjective burden of strain experienced by family caregivers of Alzheimer's patients has a profound impact on their health and well-being, even more so than the objective burden of strain that is the result of their day-to-day caregiving activities.

A Critical Review of the Study of Neuroprotective Diets to Reduce Cognitive Decline.

Alzheimer's disease (AD) and other dementias are now the seventh leading cause of death in the world and are projected to affect 115.4 million people by 2050. Delaying the onset of AD by just five years is estimated to reduce the cost and prevalence of the disease by half. There is no cure for AD nor any drug therapies to halt its progression once the disease begins. Lifestyle choices including diet are being seen as a viable complementary therapy to reduce cognitive decline, the hallmark of AD. Mediterranean, DASH (Dietary Approaches to Stop Hypertension), and MIND (Mediterranean-DASH Intervention for Neurodegenerative Delay) diets have biological mechanisms supporting their potential neuroprotective benefits, but the findings of study outcomes about these benefits have been inconsistent. This paper analyzed five Randomized Clinical Trials (RCTs) (from 2000 to 2021) and 27 observational studies (from 2010 to 2021) focused on the link between cognitive health and the Mediterranean/DASH/MIND diets to identify gaps and challenges that could lead to inconsistent results. These include a lack of accuracy in assessing food intake, multiple dietary pattern scoring systems, a shifting metric among studies focused on the Mediterranean diet, a lack of standards in the tools used to assess cognitive decline, and studies that were underpowered or had follow-up periods too short to detect cognitive change. Insights from these gaps and challenges are summarized in recommendations for future RCTs, including both pragmatic and explanatory RCTs.
