Daily Living Activities and Cognition in Aged Patients: Effect of Acute Systemic Diseases and Stroke on Leukoaraiosis
Bibliographic record
Abstract
BACKGROUND: Acute Systemic Diseases (ASD) impact on extended leukoaraiosis (ExLA) have been seldom described. We study the deterioration in daily life activities (DLA) and cognition associated with ASD events compared with the well-described impacts of stroke in patients with leukoaraiosis (L-A). METHODS: Cross-sectional surveys of aged adults from the emergency room after an acute event of ASD or stroke, hospitalized or receiving home care, were followed for one year. From 268 initial patients 206 were included in the study, all with moderate to severe L-A (Fazekas 2 and 3). The Clinical Deterioration Rating (CDR) and the modified Rankin scale with structured interview were obtained one week previous to admission and after 3 and 12 months of evolution. Comparisons were conducted within and between groups with nonparametric techniques. RESULTS: We formed three groups of similar age, A: Inpatients with one Stroke, B: Inpatients with one ASD, and C: Outpatients with one ASD. A sudden deterioration in Rankin was evident in Group A, while in B and C impairment was progressive. Impairment in CDR was smooth in all groups while in Rankin it was always greater than in cognition (CDR). No differences were found in the associations between groups and risk factors, hypertension being the most frequent one. CONCLUSION: ASD in ExL-A causes a worsening of DLA and cognition similar to that observed in ExL-A with concomitant stroke indicating the need, in ageing patients, of differential diagnosis in order to achieve the best possible treatment.

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.
