Human tau protein phosphorylated at the amino acid, serine 413 (pS413 tau), can serve as a biomarker for tauopathies such as Alzheimer's disease. Detection and quantitation of pS413 tau in a biological sample such as cerebrospinal fluid can be useful in developing therapeutics for certain tauopathies. However, pS413 tau is present in biological samples at very low levels. Thus, the invention provides a highly sensitive assay for the detection and quantitation of pS413 tau in a biological sample comprising a series of steps as described herein.

The present invention relates to a Gram-positive, anaerobic and non-spore-forming bacterium in the stool that can serve as a biomarker for diagnosing, assessing and predicting the development of dementia related diseases induced by high fat diet consumption. This was done by analyzing bacterial metagenome using cecum samples derived from AD mice models and to investigate the increase of a specific bacterium's relative abundance and its association with the disease. By using the strategy in this invention, it is possible to diagnose and predict AD at an early stage, so that it is possible to delay the onset of the disease or to prevent the onset of the disease through proper management thereby lowering the incidence of AD and improving the therapeutic effect.
