Accuracy of the Clinical Diagnosis of Alzheimer Disease at National Institute on Aging Alzheimer Disease Centers, 2005–2010
Open accessAbstract
The neuropathologic examination is considered to provide the gold standard for Alzheimer disease (AD). To determine the accuracy of currently used clinical diagnostic methods, clinical and neuropathologic data from the National Alzheimer's Coordinating Center, which gathers information from the network of National Institute on Aging (NIA)-sponsored Alzheimer Disease Centers (ADCs), were collected as part of the National Alzheimer's Coordinating Center Uniform Data Set (UDS) between 2005 and 2010. A database search initially included all 1198 subjects with at least one UDS clinical assessment and who had died and been autopsied; 279 were excluded as being not demented or because critical data fields were missing. The final subject number was 919. Sensitivity and specificity were determined based on "probable" and "possible" AD levels of clinical confidence and 4 levels of neuropathologic confidence based on varying neuritic plaque densities and Braak neurofibrillary stages. Sensitivity ranged from 70.9% to 87.3%; specificity ranged from 44.3% to 70.8%. Sensitivity was generally increased with more permissive clinical criteria and specificity was increased with more restrictive criteria, whereas the opposite was true for neuropathologic criteria. When a clinical diagnosis was not confirmed by minimum levels of AD histopathology, the most frequent primary neuropathologic diagnoses were tangle-only dementia or argyrophilic grain disease, frontotemporal lobar degeneration, cerebrovascular disease, Lewy body disease and hippocampal sclerosis. When dementia was not clinically diagnosed as AD, 39% of these cases met or exceeded minimum threshold levels of AD histopathology. Neurologists of the NIA-ADCs had higher predictive accuracy when they diagnosed AD in subjects with dementia than when they diagnosed dementing diseases other than AD. The misdiagnosis rate should be considered when estimating subject numbers for AD studies, including clinical trials and epidemiologic studies.

The Subjects section describes a diagnostic study using patients from 26 Alzheimer's disease centers, and the Results report diagnostic sensitivity and specificity. The Results also say complete information was available for only 2,188 of 3,177 patients. This 1998 paper does not establish that its dataset was complete or that the last such studies were performed in 1998 and 1999. (LLM, conf=0.83)

The Introduction (page unavailable) describes three NIA-Reagan likelihood categories and says off-diagonal plaque–tangle pairings are not clearly addressed. It does not support the count of 25 possible combinations: it describes four CERAD tiers and Braak stages 0–VI. The three categories also cover ranges of Braak stages, rather than just three individual combinations. (LLM, conf=0.88)

The introductory passage following the Abstract conclusion says GRN-associated frontotemporal lobar degeneration is clinically heterogeneous even among relatives with the same mutation, and identifies nonmendelian genetic risk factors. This supports the suggestion that phenotype is not rigidly determined by the causal mutation, but the paper does not establish a large effect of epigenetic background or environmental exposure.

The Classification section defines moderate or frequent neuritic plaques and Braak stages III–VI as scores used by the new criteria.

The Results report relatively low consistency in NIA-Reagan category assignments for cases outside the guidelines, supporting the concern behind the citing authors’ choice. But they also report high consistency for cases that match the guidelines, so the source does not support describing assignments as idiosyncratic across cases generally. The decision to stratify by CERAD and Braak scores is the citing authors’ own method, not a finding attributed to this source. (LLM, conf=0.83)

“because measures of all biomarkers studied to date have considerable overlap with those found other types of dementia (as well the cognitively normal elderly population), it remains difficult to determine whether or not cognitive impairment is due to AD or another more dominant and concurrent process.”

The section ‘Biomarker abnormalities precede clinical symptoms’ (page not provided) reports amyloid-biomarker abnormalities in 20–40% of cognitively normal elderly people, and ‘AD clinical features and pathological changes’ notes that dementia in older patients often has multiple underlying pathologies. The ‘Biomarkers of neurodegeneration’ section also says CSF tau is not specific to AD. These passages support diagnostic ambiguity, but not the broader assertion that all biomarkers studied have considerable overlap with both other dementias and cognitively normal elderly people.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-18, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-18 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
