Bibliographic record
Abstract
Kalbe E, Kessler J, Calabrese P, et al . DemTect: a new, sensitive cognitive screening test to support the diagnosis of mild cognitive impairment and early dementia. Int J Geriatr Psychiatry 2004;19:136–43.[OpenUrl][1][CrossRef][2][PubMed][3][Web of Science][4] Q Does the DemTect reliably detect mild dementia and mild cognitive impairment in older adults? ### ![Graphic][5]</img>Design: Prospective cohort study. ### ![Graphic][6]</img>Setting: Three centres in the UK; timeframe not stated. ### ![Graphic][7]</img>People: 121 people aged 45–92 years with possible mild to moderate Alzheimer’s disease (NINCDS-ARDRA criteria; Clinical Dementia Rating scale (CDR) 1 or 2). 97 people aged 45–92 years with mild cognitive impairment (Peterson criteria; CDR 0.5). 145 people aged 45–89 years with no cognitive impairment (CDR 0). Control group was divided into <60 years and ⩾60 years. Alzheimer’s disease group was divided into Mini-Mental State Examination (MMSE) ⩾21 and MMSE <21. ### ![Graphic][8]</img>Test: The DemTect includes … [1]: {openurl}?query=rft.jtitle%253DInternational%2Bjournal%2Bof%2Bgeriatric%2Bpsychiatry%26rft.stitle%253DInt%2BJ%2BGeriatr%2BPsychiatry%26rft.aulast%253DKalbe%26rft.auinit1%253DE.%26rft.volume%253D19%26rft.issue%253D2%26rft.spage%253D136%26rft.epage%253D143%26rft.atitle%253DDemTect%253A%2Ba%2Bnew%252C%2Bsensitive%2Bcognitive%2Bscreening%2Btest%2Bto%2Bsupport%2Bthe%2Bdiagnosis%2Bof%2Bmild%2Bcognitive%2Bimpairment%2Band%2Bearly%2Bdementia.%26rft_id%253Dinfo%253Adoi%252F10.1002%252Fgps.1042%26rft_id%253Dinfo%253Apmid%252F14758579%26rft.genre%253Darticle%26rft_val_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Ajournal%26ctx_ver%253DZ39.88-2004%26url_ver%253DZ39.88-2004%26url_ctx_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Actx [2]: /lookup/external-ref?access_num=10.1002/gps.1042&link_type=DOI [3]: /lookup/external-ref?access_num=14758579&link_type=MED&atom=%2Febmental%2F7%2F3%2F70.atom [4]: /lookup/external-ref?access_num=000189096800005&link_type=ISI [5]: /embed/inline-graphic-1.gif [6]: /embed/inline-graphic-2.gif [7]: /embed/inline-graphic-3.gif [8]: /embed/inline-graphic-4.gif

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
