The National Institutes of Health (NIH) has announced a funding opportunity titled "Novel Mechanism Research on Neuropsychiatric Symptoms (NPS) in Alzheimer's Dementia," aimed at enhancing the understanding of mechanisms associated with NPS in individuals with Alzheimer's disease (AD) or Alzheimer's disease-related dementias (ADRD). This initiative encourages innovative research proposals that explore both neurobiological and behavioral pathways, potentially leading to novel therapeutic approaches for treating and preventing NPS. The R21 exploratory/developmental grant mechanism is particularly suited for high-risk projects without preliminary data, while R01 grants are recommended for longer-term studies with existing findings. Interested applicants must adhere to NIH guidelines and submit their proposals by September 7, 2026, with a maximum funding amount of $275,000. For further inquiries, applicants can contact NIH Grants Information at grantsinfo@nih.gov or visit the opportunity's webpage at https://grants.nih.gov/grants/guide/pa-files/PAR-23-208.html.
