 measuring the level of pathologically modified or aggregated tau in a sample from a human subject with an anti-tau antibody or tau-binding fragment thereof, wherein the anti-tau antibody or tau-binding fragment thereof comprises a VH comprising VH complementarity determining regions 1, 2, and 3 of the amino acid sequences set forth in any one of SEQ ID NO: 44, 45, 50, 56, 67, 69, or 71; and a VL comprising VL complementarity determining regions 1, 2, and 3 of the amino acid sequences set forth in any one of SEQ ID NO:46, 221, 222, 51, 57, 68, 70, or 72; and   comparing the level of modified or aggregated tau to a reference standard that indicates the level of the pathologically modified or aggregated tau in one or more control subjects,   wherein a difference or similarity between the level of pathologically modified or aggregated tau and the reference standard indicates that the human subject has a neurodegenerative tauopathy.   
     
     
         73 . An antibody or antigen-binding fragment thereof that binds to human tau and comprises:
 a VH comprising VH complementarity determining regions 1, 2, and 3 of the amino acid sequences set forth in any one of SEQ ID NO: 44, 45, 50, 56, 67, 69, or 71; and a VL comprising VL complementarity determining regions 1, 2, and 3 of the amino acid sequences set forth in any one of SEQ ID NO:46, 221, 222, 51, 57, 68, 70, or 72,   wherein the antibody or antigen-binding fragment thereof comprises polyethylene glycol or a detectable label selected from the group consisting of an enzyme, a radioisotope, a fluorescent compound, a chemiluminescent compound, a bioluminescent compound, and a heavy metal.   
     
     
         74 . An anti-tau single chain antibody or scFv antibody comprising:
 a VH comprising VH complementarity determining regions 1, 2, and 3 of the amino acid sequences set forth in any one of SEQ ID NO: 44, 45, 50, 56, 67, 69, or 71; and   a VL comprising VL complementarity determining regions 1, 2, and 3 of the amino acid sequences set forth in any one of SEQ ID NO:46, 221, 222, 51, 57, 68, 70, or 72.
