pubmed:abstractText |
Alzheimer's disease, the most common cause of dementia, is multifactorial and heterogeneous; its diagnosis remains probable. We postulated that more than one disease mechanism yielded Alzheimer's histopathology, and that subgroups of the disease might be identified by the cerebrospinal fluid (CSF) levels of proteins associated with senile (neuritic) plaques and neurofibrillary tangles. We immunoassayed levels of tau, ubiquitin, and Abeta(1-42) in retrospectively collected CSF samples of 468 clinically diagnosed Alzheimer's disease patients (N = 353) or non-Alzheimer's subjects (N = 115). Latent profile analysis assigned each subject to a cluster based on the levels of these molecular markers. Alzheimer's disease was subdivided into at least five subgroups based on CSF levels of Abeta(1-42), tau, and ubiquitin; each subgroup presented a different clinical profile. These subgroups, which can be identified by CSF analysis, might benefit differently from different therapeutic drugs.
