427 Cognitive Function and Catastrophizing in the Adult Deformity Population: Single Center Series of 111 Patients
Bibliographic record
Abstract
INTRODUCTION: Baseline cognitive impairment (CI) in adult spinal deformity (ASD) pts is unknown and may affect how they report PROMs/experience pain. Goal of this study was to determine baseline CI prevalence and how it’s related to PROMs/pain catastrophizing. METHODS: Single center prospective study. PROMs included the Montreal Cognitive Assessment(MOCA), Pain Catastrophizing Scale (PainCS), back pain numerical score, Oswestry Disability Index(ODI), and Scoliosis Research Society-22 (SRS22) questionnaires. Pts were stratified by normal cognition (MOCA scores 26-30), mild CI (MOCA 18-25), moderate CI (MOCA 10-17) and Severe CI (MOCA <10). PainCS (higher = more catastrophizing) has total scor e(T,max = 52) and 3 subdomains (Rumination [R,max = 16], Magnification [M,max = 12], Helplessness [H,max = 24]). Comparisons were made between pts with normal (NORM) and any type of CI (CI) as well as correlations between MOCA and PROMS. MOCA scores were compared postop. RESULTS: Total 111 pts enrolled (mean age 64.1 ± 9.8 yrs, 57.5% F). Mean baseline MOCA score was 25.0±3.0 (mild CI, range 14-30), 59/111(53.1%) had mild/moderate CI. No severe CI. CI pts had significantly higher mean baseline PainCS-T, PainCS-R, and PainCS-M scores than NORM. CI pts had significantly worse baseline ODI (55.2 ± 15 vs 47.9 ± 14.4, p = 0.02) but better self-reported SRS Mental score (3.3 ± 1 vs 2.7 ± 0.8, p = 0.004) than NORM. Lower baseline MOCA scores significantly correlated with higher baseline ODI(r=-0.24,p=0.015), SRS Mental (r = -0.21, p = 0.037), current back pain (r = -0.26, p=0.006), and PainCS-R (r=-0.38, p<0.001), PainCS-M(r = -0.37, p < 0.001), PainCS-H (r = -0.27, p = 0.004), PainCS-T(r = -0.36, p < 0.001). Mean pre/postop MOCA scores were not significantly different (p > 0.05). CONCLUSIONS: Baseline CI is frequent in ASD pts and associated with higher baseline pain/disability and pain catastrophizing compared to ASD pts with normal cognition. The CI persists postoperatively.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
