Abstract

Alzheimers Dement. 2025 Jul;21(7):e70309. doi: 10.1002/alz.70309.

ABSTRACT

INTRODUCTION: The Down syndrome-associated Alzheimer's disease (DSAD) autosomal dominant Alzheimer's disease (ADAD) 2024 Conference in Barcelona, convened under an Alzheimer's Association International Society to Advance Alzheimer's Research and Treatment (ISTAART) grant through the Down syndrome and Alzheimer's disease (AD) Professional Interest Area (PIA), brought together global researchers to foster collaboration and knowledge exchange between the fields of DSAD and ADAD.

METHODS: This article provides a synthesis review of the conference proceedings, summarizing key discussions on biomarkers, natural history models, clinical trials, and ethical considerations in anti-amyloid therapies.

RESULTS: A total of 211 attendees from 16 countries joined the meeting. Global researchers presented on disease mechanisms, therapeutic developments, and patient care strategies. Discussions focused on challenges and opportunities unique to DSAD and ADAD. Experts emphasized the urgent need for tailored clinical trials for ADAD and DSAD and debated the safety and efficacy of anti-amyloid treatments. Ethical considerations highlighted equitable access to therapies and the crucial role of patient and caregiver involvement.

DISCUSSION: The conference highlighted the importance of inclusive research and collaboration across the genetic forms of AD.

HIGHLIGHTS: Biomarker research and natural history models developed in Down syndrome-associated Alzheimer's disease (DSAD) and autosomal dominant Alzheimer's disease (ADAD) enable the prediction of disease progression not only for DSAD and ADAD, but also for sporadic Alzheimer's disease (AD). -Collaboration and knowledge exchange among researchers across these genetic forms of AD will accelerate our understanding of the pathophysiology and advance preventive trials in DSAD and ADAD. -Tailored clinical trials for DSAD are urgently needed to address specific safety and efficacy concerns. -Inclusive research practices are crucial for advancing treatments and understanding of DSAD and ADAD.
