Measuring certain proteins in spinal fluid can accurately diagnose Alzheimer's and predict which patients with memory problems will develop the fatal brain-wasting disease, Belgian researchers said Monday.
And they may also help identify early signs of the disease in healthy people, the team reported in the Archives of Neurology.
"The unexpected presence of the Alzheimer's disease signature in more than one-third of cognitively normal subjects suggests that Alzheimer's disease pathology is active and detectable earlier than has heretofore been envisioned," Geert De Meyer of Ghent University in Belgium and colleagues wrote.
