Summary

In this lecture, Professor Selina Wray provides an overview of dementia research, focusing on Alzheimer’s disease. She explains the difference between dementia and Alzheimer’s, highlights the prevalence and impact of the disease, and discusses the genetic discoveries that have shaped our understanding, particularly the amyloid cascade hypothesis. She emphasizes the importance of early intervention and describes recent advances in blood-based biomarkers and disease-modifying therapies. The core of her talk centers on her own research using patient-derived stem cell models to study the earliest molecular changes in Alzheimer’s and frontotemporal dementia. She illustrates how these models can reveal disease mechanisms and aid in drug development. She also discusses the future of dementia research, including the role of big data, AI, and international collaborations. The lecture concludes with a Q&A session where she addresses questions about the practicality of stem cell models, the challenges of translating research into treatments, and the importance of public engagement.
