Differentiation of the pattern of cognitive impairment between depressed and non-depressed patients with dementia living in long-term care facilities
Bibliographic record
Abstract
OBJECTIVE: The principal objective of this study is to examine the cognitive profile of patients with dementia plus (D+ group) and without (D- group) concomitant depression. METHOD: The D+ (N = 61) and D- (N = 89) patients were recruited in long-term care facilities. The depression status of the participants was determined using the Cornell Scale for Depression in Dementia. Cognitive functioning was assessed using the Hierarchic Dementia Scale (HDS). RESULTS: The analyses first indicated that on the total HDS score, patients of the D+ group exhibited more severe cognitive impairment compared to those of the D- group. Further analyses revealed that the difference between groups pertained to perception, attention/memory, calculation, and language functions. Moreover, secondary analyses revealed that the cognitive deficits of the D+ group were associated with behavioral (agitation and retardation, in particular), but not with mood-related, symptoms of depression. Interestingly, ideational symptoms of depression (suicide and self-depreciation, in particular) were positively correlated with cognitive impairment. CONCLUSION: These findings add to those of previous studies showing that D+ and D- patients differ not only regarding the presence or absence of depressive symptoms, but also regarding cognitive manifestations. This study thus reinforces the need to detect and treat accurately depression in dementia.

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.
