The Family Caregiving Research and Innovation Act proposes significant amendments to the Older Americans Act of 1965, primarily focusing on enhancing support and understanding of family caregivers. A key provision authorizes $30,000,000 annually for fiscal years 2026 through 2030 to fund the Research, Demonstration, and Evaluation Center for the Aging Network. This funding is specifically designated for conducting comprehensive research and evaluation activities to bolster data, research, and evidence-based practices related to family caregivers. The bill also substantially revises the definition of a "family caregiver" under the Act. The updated definition now explicitly includes an adult family member or informal provider of in-home and community care to an older individual or an individual of any age with Alzheimer's or a related disorder, or an "older relative caregiver." It clarifies that care provided primarily through a financial or professional agreement is excluded. Furthermore, a new definition for "older relative caregiver" is introduced, specifying individuals aged 55 or older who are primary caregivers for a child or an individual with a disability, with detailed criteria for each. These definitional changes lead to several conforming amendments within the National Family Caregiver Support Program . The bill streamlines language by integrating "older relative caregivers" into the broader "family caregiver" term for program descriptions and eligibility. It also clarifies that while services are generally for family caregivers, respite care and supplemental services for caregivers of older individuals are subject to specific eligibility conditions for the care recipient.
