Ars Technica investigates a fundamental challenge to decades of Alzheimer's research, reporting that the dominant focus on amyloid may represent a scientific dead-end rather than the disease's root cause. The article examines how researchers may have pursued the wrong pathway, and explores emerging evidence suggesting alternative mechanisms warrant investigation. This reassessment could reshape future therapeutic approaches to Alzheimer's treatment.
