これは何か

Beta-amyloid comes from breakdown of a larger amyloid precursor protein and can collect between neurons as plaques in Alzheimer disease.[1]

なぜ重要か

Anti-amyloid antibodies target amyloid biology and have been approved for certain early Alzheimer disease contexts.[2,3]

どの判断に影響するか

解釈上の注意

  • Removing or reducing amyloid is not the same as promising restoration of lost memory or full disease reversal.[1,2]
