The "Dementia Dignity and Advance Care Planning Act" aims to enhance the rights of individuals diagnosed with Alzheimer's disease and other neurodegenerative dementias by allowing them to create Dementia-Specific Advance Directives (DSADs). These directives enable competent adults to specify their health care preferences for advanced stages of dementia, including decisions about feeding, hospitalization, and life-prolonging measures. The act outlines the requirements for executing a DSAD, such as being signed and witnessed, and allows individuals to revoke their directives while retaining decisional capacity.

Additionally, the act mandates the establishment of a secure electronic Dementia Advance Directive Registry by the Department of Health, which will provide real-time access to health care professionals. It also requires training programs for health care staff on dementia-specific advance care planning and ensures that all licensed health care facilities honor valid DSADs. The bill includes provisions for immunity from liability for health care providers acting in good faith reliance on a DSAD and emphasizes the importance of respecting patients' wishes in care decisions.
