Peripheral Biomarkers of Alzheimer's Disease

TL;DRAbstract

Currently available diagnostic tests have moved the field closer to early diagnosis of Alzheimer's disease (AD); however, a definitive diagnosis is made only with the development of clinical dementia and the presence of amyloid plaques and neurofibrillary tangles at autopsy. An ideal antemortem AD biomarker should satisfy the following criteria: the ability to diagnose AD with high sensitivity and specificity as confirmed by the gold standard of autopsy validation; the ability to detect early-stage disease and track the progression of AD; and monitor therapeutic efficacy. AD biomarker technologies currently under development include in vivo brain imaging with PET and MRI (i.e., imaging of amyloid plaques, biochemical assays in cerebrospinal fluid (CSF) and peripheral tissues. CSF biomarkers have received increased attention in the past decade. However, it is unclear whether these biomarkers are capable of early diagnosis of AD, prior to Aβ accumulation, or whether they can differentiat
