The present invention provides methods for identifying biomarkers of disease capable of affecting cognitive function. The biomarkers identified by the methods of the prevention may be used for predicting whether a mammal will develop a disease capable of affecting cognitive function. More specifically, the present invention relates to the identification of biomarkers predictive of neurological diseases in mammal and the use of these biomarkers in the diagnosis, differential diagnosis and/or prognosis of the neurological disease. The methods and systems provided enable an assessment and theoretical prediction of neocortical amyloid loading based on the measurement of biomarkers that will provide an indication of whether a mammal is likely to develop a neurological disease.
