✓ Peer-reviewed alzhub usefulness score 64 out of 100. Getting a diagnosis

Topic: Amyloid, tau and blood-test diagnosis

We envision that defining AD as a biological construct will enable a more accurate characterization and understanding of the sequence of events that lead to cognitive impairment that is associated with AD, as well as the multifactorial etiology of dementia.

Key findings

Why it matters

This 2018 NIA-AA paper proposes, for research use, defining Alzheimer's disease by biology rather than by symptoms alone. Its authors "envision" that this will give a more accurate picture of "the sequence of events that lead to cognitive impairment" and of the "multifactorial etiology of dementia", but this is a stated aim, not a tested result. The paper reports no patient data and offers no test, treatment or cure.
