(Newser) – The presence of certain biomarkers in spinal fluid can predict the development of Alzheimer's disease, even in patients who display no symptoms, according to breakthrough research being published tomorrow. "This is what everyone is looking for, the bull’s eye of perfect predictive accuracy," a doctor not connected with the study tells the New York Times. "This is literally on the cutting edge of where the field is."

The proteins A1-42, T-tau, and P-tau were present in the cerebrospinal fluid of 90% of Alzheimer's patients studied, as well as 72% of subjects with mild cognitive impairment and 36% of unimpaired subjects. That confirms the disease begins to develop before symptoms become apparent, the LA Times explains.
