Early diagnosis of Alzheimer’s disease is important to ensure timely and accurate treatment. We show that a blood-based circular RNA signature can accurately detect Alzheimer’s disease as well as, or better than, current biomarkers and even predict who will develop symptoms before they appear. This less invasive approach could offer earlier diagnosis and improved monitoring of Alzheimer’s disease.
