The Addressing SILO Act of 2026 directs the federal government to provide grants to area agencies on aging and community-based organizations to help combat social isolation and loneliness among older adults and people with disabilities. The bill requires these organizations to conduct outreach to identify at-risk individuals, develop evidence-based community programs to address isolation, connect people with social and clinical support services, and evaluate program effectiveness. The legislation also establishes training programs to help these organizations improve their capacity to prevent and address isolation, with a priority given to models that coordinate with medical-legal partnerships. Congress will receive evaluation reports every three years starting three years after enactment. The bill appropriates 62.5 million dollars annually for fiscal years 2026 through 2030 to implement these grants and training programs.
