Detecting Alzheimer’s disease before symptoms become debilitating has long been a "holy grail" for neurologists, particularly as newer pharmacological treatments require early intervention to remain effective.

Researchers at Mass General Brigham are now leveraging artificial intelligence and computer vision to analyze brain scans with a level of precision previously unattainable by human observation alone. By identifying microscopic structural changes in the brain, the AI system can predict the onset of the disease with nearly 93 percent accuracy. This breakthrough is critical given that roughly 90 percent of individuals in the "mild cognitive impairment" phase—the earliest stage of the disease—currently go undiagnosed in the United States.

Dr. Lidia Moura, a director within the neurology department at the institution, emphasizes that the most significant opportunity for improving patient outcomes lies not in the development of more potent drugs, but in detecting signs of the disease much earlier. As pharmaceutical companies release medications that modestly slow cognitive decline, the diagnostic bottleneck has become the primary hurdle.

This shift toward AI-driven diagnostics represents a move from reactive to proactive care. By integrating these tools into clinical workflows, healthcare systems can identify at-risk populations years before major memory loss occurs, potentially transforming a terminal diagnosis into a manageable chronic condition through early lifestyle and pharmacological interventions.
