Abstract

The National Institute on Aging and the Alzheimer's Association charged a workgroup with the task of revising the 1984 criteria for Alzheimer's disease (AD) dementia. The workgroup sought to ensure that the revised criteria would be flexible enough to be used by both general healthcare providers without access to neuropsychological testing, advanced imaging, and cerebrospinal fluid measures, and specialized investigators involved in research or in clinical trial studies who would have these tools available. We present criteria for all‐cause dementia and for AD dementia. We retained the general framework of probable AD dementia from the 1984 criteria. On the basis of the past 27 years of experience, we made several changes in the clinical criteria for the diagnosis. We also retained the term possible AD dementia, but redefined it in a manner more focused than before. Biomarker evidence was also integrated into the diagnostic formulations for probable and possible AD dementia for use in research settings. The core clinical criteria for AD dementia will continue to be the cornerstone of the diagnosis in clinical practice, but biomarker evidence is expected to enhance the pathophysiological specificity of the diagnosis of AD dementia. Much work lies ahead for validating the biomarker diagnosis of AD dementia.

  • A consensus meeting was held among study neurologists and neuropsychologists to clinically determine each potential participant's cognitive status grouping based on a standardized approach used in NIH-funded Alzheimer's Disease Centers.

    “A consensus meeting was held among the study neurologists and neuropsychologists to clinically determine each potential participant’s cognitive status grouping (NC, MCI, or dementia) based on a standardized approach used in National Institute of Health (NIH)-funded Alzheimer’s Disease Centers across the United States (Albert et al., 2011; Jack et al., 2011; McKhann et al., 2011).”

    From Internet-Based Conversational Engagement Randomized Controlled Clinical Trial (I-CONECT) Among Socially Isolated Adults 75+ Years Old With Normal Cognition or Mild Cognitive Impairment: Topline Results (2024) · cites this paper as McKhann et al., 2011

    Section 2, “Criteria for all-cause dementia,” supports using clinical judgment to distinguish dementia from MCI. It does not describe a consensus-meeting procedure or establish that this approach is standardized across NIH-funded Alzheimer’s Disease Centers. The meeting of the citing study’s own clinicians is its reported method, not a finding attributed to McKhann et al. (LLM, conf=0.82)

  • Atrophy of specific brain regions shown by structural MRI is an important part of the diagnostic criteria for FTD and AD.

    “the atrophy of specific brain regions shown by structural MRI is an important part of the diagnostic criteria for FTD and AD (McKhann et al., 2011; Rascovsky et al., 2011)”

    From Deep Learning-Based Classification and Voxel-Based Visualization of Frontotemporal Dementia and Alzheimer's Disease (2021) · cites this paper as McKhann et al., 2011

    Section 6 identifies atrophy in specific temporal and parietal regions on structural MRI as an AD biomarker included in the diagnostic framework. But it says biomarkers are optional tools that may increase diagnostic certainty, not part of the core clinical criteria or recommended for routine diagnosis. The sentence also cites Rascovsky et al. for FTD; this verdict assesses McKhann et al.’s support for the AD portion only. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Diagnosis of Alzheimer's disease was made in accordance with NINCDS-ADRCA criteria and mild cognitive impairment was diagnosed according to Mayo criteria.

    “Diagnosis of AD was made in accordance with the NINCDS-ADRCA criteria (McKhann et al., 2011) and MCI was diagnosed according to the Mayo criteria (Petersen et al., 1999).”

    From Mean diffusivity in cortical gray matter in Alzheimer's disease: The importance of partial volume correction (2018) · cites this paper as McKhann et al., 2011

    The Introduction identifies the NINCDS–ADRDA criteria as the 1984 criteria for diagnosing AD and says this paper revises them. The paper therefore supports the criteria named in the AD portion of the sentence, but it is not the original NINCDS–ADRDA criteria publication. The separately cited Mayo criteria for MCI are not attributed to this source. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • During the extended preclinical period prior to dementia diagnosis, many patients develop behavioral or neuropsychiatric changes, including agitation, irritability, decreased motivation, loss of empathy, and depression, which increase the risk of transition to mild cognitive impairment and AD.

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.

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.
