Significant developments highlighted in dementia research

Among the most impactful developments highlighted in the report are:

• Anti-amyloid immunotherapies: New FDA-approved therapies for early Alzheimer’s, including lecanemab and donanemab, shown to slow cognitive decline by targeting beta-amyloid proteins. These advancements build on decades of NIH-funded research in molecular biology and brain imaging.

• Biomarker discovery and diagnostics: Blood-based biomarkers, PET imaging, and advanced MRI techniques are improving early detection and precision in tracking disease progression. These tools also open the door to more targeted clinical trials and personalized treatment plans.

• Lifestyle and prevention studies: Expanding evidence shows how interventions such as physical activity, cognitive training, and cardiovascular health management can delay or reduce dementia risk. The NIH’s POINTER trial is one of the largest efforts to explore these interventions in real-world settings.

• Drug discovery pipelines: Beyond amyloid, researchers are investigating tau protein, inflammation pathways, and vascular contributions to dementia — diversifying the potential avenues for new therapies.

• Care and caregiving innovations: NIH has expanded research into care delivery, caregiver support, and health equity, including technology-enabled interventions to improve quality of life for both people living with dementia and their families.

• Data-sharing and collaboration: Initiatives such as the Alzheimer’s Disease Data Initiative and global collaborations are accelerating progress by making large datasets available for researchers worldwide.
