Summary WebFeb 17, 2024 · The new blood test, which performs comparably to existing brain scan- or spinal tap-based tests, could lower costs and expand the availability of diagnostic studies for Alzheimer’s disease. Alzheimer’s is characterized by the buildup of a protein called beta-amyloid, which forms sticky plaques on the brain and can cause brain cells to die. WebThe same cerebrospinal fluid (CSF) tests used in early-onset Alzheimer's disease (AD) are used in late-onset AD (see Cerebrospinal Fluid Tests). However, genetic tests for late-onset AD are different from those used for early-onset AD.
