Brain-based index may reveal Alzheimer's risk patterns in adults as young as 30

Over the past few decades, neuroscientists and medical researchers worldwide have been trying to leverage available health records, brain scans and other medical data to uncover biological markers associated with the onset of specific diseases or neuropsychiatric disorders. The identification of these biomarkers could help to devise new tools to predict the risk that individual patients will develop a specific condition, allowing doctors to intervene early, preventing or delaying its emergence or slowing down its progression.
