The present invention relates to methods for diagnosing and/or treating Alzheimer's Disease (AD) by detecting in a human sample the levels of one or more of the metabolites galactose, imidazole acetone, creatinine, and 5-aminopentanoate; diagnosing the patient with AD when one or more of the metabolites galactose, imidazole acetone, creatinine, and 5-aminopentanoate in the sample is at a different level than a statistically validated threshold for the respective metabolite. In some embodiments, the AD is diagnosed and the patient is treated for AD.
