HAI 2026
Dear Colleagues, Innovators, and Friends,
As we turn the page on another year, I find myself once again reflecting with deep appreciation on the incredible community that has grown around the HAI conference. What started in 2007 as a modest gathering of like-minded researchers has evolved into a cornerstone of the Alzheimer’s imaging field—thanks entirely to your energy, curiosity, and shared commitment to advancing our understanding of neurodegenerative disease.
Over the years, HAI has served not only as a platform for the latest scientific breakthroughs, but also as a space where new ideas are born, collaborations take root, and future leaders of the field are mentored and supported. This spirit of scientific camaraderie is what makes HAI so unique, and it’s what brings me back with renewed energy year after year.
I’m delighted to share that HAI 2026 will be held once again in beautiful San Juan, Puerto Rico, at the Puerto Rico Convention Center, from Monday, January 12 through Wednesday, January 14. We’ve shifted the meeting days to accommodate the local San Sebastián Festival, and I trust that the slight change in rhythm will only add to the vibrancy of our gathering.
More information, including abstract deadlines and program updates, will be shared in the coming weeks. For now, I encourage you to save the dates and begin making plans to join us. I look forward to another memorable meeting—one filled with great science, familiar faces, and new connections.
Warm regards,
Keith A. Johnson, MD
OBJECTIVES
1.
2.
Data analysis procedures discussed will include voxel-based and region-based imaging approaches, masking for vulnerable regions, evaluation of reference regions or standards, choice of statistical procedures and specific use of control groups from older age groups. Important topics include data harmonization methods for imaging and biofluid biomarkers.
3.
Neuropathology concepts will be discussed in the context of applications that include further characterization of neurodegeneration in AD and related disorders, disease subtypes, disease staging, and risk factors. Additional investigations of importance include neuropathological evaluation of PET radiotracer properties (e.g., distribution, localization of specific and off-target binding) and correspondence between antemortem PET and postmortem measures.
4.
Biofluid biomarker development, validation, and application in AD and related disorders will be discussed. This will include efforts to understand relationships across established and emergent biofluid biomarkers and comparison of these outcomes to amyloid and tau PET measures.
5.
The concept of biomarker positivity will continue to be extensively discussed, and the attendees should be able to characterize the advantages and disadvantages of both dichotomized and continuous variable approaches to imaging and non-imaging biomarkers relevant to the human amyloid imaging field and with respect to specific purposes or intended uses of the outcome.
6.
Attendees will have the opportunity to evaluate amyloid and tau data in specific clinical and clinical research contexts, including review of typical findings in AD dementia, mild cognitive impairment due to AD, and in clinically normal individuals. This includes further elucidation of factors that underlie relationships between amyloid and tau deposition, cognitive decline, and dementia progression that provide a more informed understanding of individual patient trajectories. These efforts will also be related to familial forms of the disease, Down Syndrome, and to non-AD processes (i.e., fronto-temporal lobar degeneration and Lewy Body dementia). Further study of “real world” research participants will be discussed that includes people from diverse, ethnic and/or racial minority, and disadvantaged groups.
7.
Particular attention will be given to the assessment of longitudinal amyloid and tau PET data as it relates to methods of analysis and comparison to other domains of data, including structural and functional brain imaging data, and clinical and cognitive outcomes. An ongoing topic of importance is the relative value of PET versus other detection strategies (e.g., MRI volumetry and biofluid biomarkers).
8.
Attendees will also continue to have the opportunity the better understand methodology that can be used to optimize participant selection and conduct of AD therapeutic trials. Important topics relate to improved understanding of how in vivo metrics (imaging and non-imaging) and cognition change in response to AD therapeutic treatment (cross-sectionally and longitudinally) and how to better identify those most vulnerable to treatment side-effects, such as anti-amyloid related imaging abnormalities.
