WebAlzheimer's disease (AD) is as a continuum entailing a preclinical phase, where individuals are cognitively unimpaired but amyloid-β (Aβ) and tau pathology have begun, followed by a clinical phase (including mild cognitive impairment and dementia). In the preclinical Alzheimer stage, Aβ and tau progressively accumulate over 2 decades or more. On top …
Prediction of Longitudinal Cognitive Decline in Preclinical Alzheimer
WebBiomarkers of AD have the potential to support preclinical diagnosis and predict disease progression. Currently, the most commonly used biomarker detection method in clinical research and routine diagnosis is ELISA, which is used to measure the levels of Aβ42, T-tau, and P-tau in cerebrospinal fluid.
