It directs U.S. leadership in international cooperation on dementia, authorizes use of certain foreign assistance funds for contributions with required matching and limits on the U.S. share for 2026–2030, and requires a presidential designee to coordinate with USAID, the State Department, and HHS and to report to Congress within 180 days and annually thereafter.

Declares U.S. policy to lead global efforts against Alzheimer’s and dementia, encourages outreach to low- and middle-income countries, and sets transparency and oversight steps (coordination, matching/limit rules, and reporting) tied to any U.S. participation and funding of the DAC.
