The National Institutes of Health (NIH) is preparing to publish a Notice of Funding Opportunity (NOFO) aimed at advancing research on biomarkers of cognitive decline and dementias in individuals on the Autism Spectrum. This initiative seeks to conduct observational studies utilizing deep phenotyping techniques, including neuroimaging and molecular approaches, to identify and characterize neurodegeneration biomarkers in this population, as well as to evaluate existing dementia biomarkers in the context of Autism Spectrum Disorders (ASD). The total estimated funding for this program is $5 million, with the NOFO expected to be published in December 2024 and applications due by February 2025, leading to awards anticipated by September 2025. Interested applicants are encouraged to prepare collaborative proposals in advance of the official announcement.
