Key findings used in wiki

Scale and burden of dementia caregiving

  • More than 7.2 million Americans have Alzheimer's disease; 11 million+ provide unpaid care for people with Alzheimer's or other dementias (Alzheimer's Association 2025 Facts and Figures).
  • 11.9 million U.S. caregivers provided 19.2 billion hours of care in 2024, valued at $413.5 billion at minimum wage.
  • Worldwide direct and informal costs of dementia exceeded 1% of global GDP in 2019 ($1.313 trillion), with informal care accounting for ~40% of that total.

Caregiver mental and physical health impact

  • 59% of dementia caregivers rate emotional stress as high; 30–40% meet criteria for depression; 44% report anxiety.
  • Spousal dementia caregivers have roughly 2.5× higher odds of depression than non-spousal dementia caregivers.
  • 38% report high or very high physical stress. Dementia caregivers are more likely than non-dementia caregivers to report fair/poor health, elevated stress hormones, reduced immune function, slow wound healing, new hypertension, and new coronary heart disease.
  • 56% report financial stress, 53% report family conflict, and 45% nonetheless report caregiving as very rewarding — the strain and meaning dimensions coexist.

The NYU Caregiver Intervention (NYUCI) — efficacy evidence

  • Original randomized controlled trial funded by NIH from 1987–2010: 406 spouse-caregivers of people with Alzheimer's disease, followed up to 18 years.
  • NYUCI is a multi-component psychosocial intervention — individual counseling, family counseling, support groups, and ad hoc counseling as needed, tailored to the family and to disease stage.
  • Effects in the original trial: improved caregiver-perceived support, reduced caregiver depression, reduced stress reactivity to patient behavior, improved self-rated health, reduced depressive symptoms and burden during nursing home transition, and persisting effects on depression through bereavement.
  • Social support was the mediator of all other outcomes — which is why GiveCare treats social support as a first-order construct rather than a nice-to-have.
  • Time to nursing home placement for people with Alzheimer's disease was delayed by the intervention (Mittelman et al., Neurology 2006; 67:1592–1599).
  • Cost savings have been modeled at state and national scale (Long et al., Health Affairs 2014).
  • The 3-country replication (US/England/Australia) showed a sustained reduction in caregiver depression over 24 months, with country-level differences in nursing home placement effects.

Policy and delivery context

  • CMS GUIDE Model (Guiding an Improved Dementia Experience) is an alternative payment approach for comprehensive, coordinated dementia care management — explicit recognition that dementia care is not purely medical.
  • Effective evidence-based psychosocial interventions for informal caregivers share five characteristics: caregivers are actively involved; the intervention is tailored and flexible; it enhances caregiver competency; it offers emotional support; and it meets the needs of both caregiver and person with dementia.

Why it matters for the wiki

  • Provides current, citable national statistics on dementia caregiver load and health impact.
  • Establishes that there is RCT-grade evidence for psychosocial caregiver intervention in dementia — relevant to how GiveCare positions its own caregiver-support claims.
  • Identifies social support as the causal mediator of outcomes, which is why support/index.md can carry that claim directly.
