A New Era for Alzheimer's Disease Diagnosis

Emerging biomarkers and digital tools are unlocking earlier and more accurate diagnoses. Disease-modifying therapies such as Leqembi and Kisunla have recently emerged as treatment options. These work by binding to toxic molecules associated with the disease, triggering the body's immune system to clear them. Although they have been shown to moderately slow disease progression, their effectiveness hinges on timely and accurate diagnosis. Alzheimer's, however, is still routinely misdiagnosed or diagnosed too late, often after irreversible brain damage has occurred.
