✓ Peer-reviewed alzhub usefulness score 58 out of 100. Getting a diagnosis

Topic: Amyloid, tau and blood-test diagnosis

Clinical criteria for the diagnosis of Alzheimer's disease include insidious onset and progressive impairment of memory and other cognitive functions. There are no motor, sensory, or coordination deficits early in the disease. The diagnosis cannot be determined by laboratory tests. These tests are important primarily in identifying other possible causes of dementia that must be excluded before the diagnosis of Alzheimer's disease may be made with confidence. Neuropsychological tests provide confirmatory evidence of the diagnosis of dementia and help to assess the course and response to therapy. The criteria proposed are intended to serve as a guide for the diagnosis of probable, possible, and definite Alzheimer's disease; these criteria will be revised as more definitive information become available.

Key findings

Why it matters

These 1984 criteria describe how to diagnose probable, possible, and definite Alzheimer's disease clinically, noting that no laboratory test can determine the diagnosis and that other causes of dementia must be excluded. They are diagnostic guidance, not a treatment or prevention for the disease.

Published in a leading specialty journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on institution's track record, so that was left out: it earned 56 of the 97 points we could judge it on, which is 58 out of 100.
