WebFeb 19, 2024 · Alzheimer’s disease (AD) is a slowly progressive neurodegenerative disease that currently lacks effective treatment. The first detectable pathology of the disease is the accumulation of 42 amino acid-long amyloid β (Aβ) protein in extracellular plaques in the brain, which occurs decades before clinical symptom onset [ 1 ]. WebIn Alzheimer disease (AD) brain tau is ∼three to four-fold more hyperphosphorylated than the normal adult brain tau and in this hyperphosphorylated state it is polymerized into paired helical filaments ([PHF) admixed with straight filaments (SF) forming neurofibrillary tangles.
