The impact of neuropsychiatric symptoms in in PSP. An overview of quality of life and functionality
Bibliographic record
Abstract
Abstract Background Progressive supranuclear paralysis (PSP) is an atypical parkinsonian disorder associated with oculomotor features, motor disturbances, postural instability along with cognitive problems and neuropsychiatric symptoms. Functional impairment and quality of life (QOL) are often related to the motor symptoms. Our aim was to investigate the contribution of neuropsychiatric symptoms such as depression, anxiety and sleep disturbance to functionality and QOL. Method We used data from 69 patients meeting criteria for probable PSP from the Rossy PSP Centre. Neuropsychiatric symptoms, severity and functionality were examined using validated rating scales including the Hamilton Anxiety Rating Scale (HAM‐A) for anxiety, Geriatric Depression Scale (GDS) for depression, Epworth sleepiness scale (ESS) for sleep and Neuropsychiatry Inventory (NPI) total scores. To examine function, we used the Schwab and England Activities of Daily Living Scale (SEADL), severity of disease we used PSP rating scale and for QOL the (EQ‐5D‐5L). Cognition was examined using the Montreal Cognitive Assessment (MOCA). We investigated the relationships between neuropsychiatric symptoms and function and QOL using Pearson correlations controlling for multiple comparisons with false discovery test. Result In our sample (37.7% female, mean age 71.2+/‐ 6.5) 26.9% had depression, 13% had anxiety, 97.3% had scores compatible with cognitive impairment. Mean QOL‐EQ‐5D‐5L score was 50.4 +/‐ 25.3, mean PSP‐RS 39.5 +/‐ 12.7. Subgroups were made for QOL and functionality analysis. We found negative correlations between SEADL and HAM‐A (r ‐0.32 p = 0.01), and GDS (r ‐0.32 p = 0.01); between QOL‐EQ‐5D‐5L and GDS (r‐0.51 p = 0.014) and HAM‐A (r‐0.49 p = 0.014). Positive correlations were found between SEADL and QOL‐EQ‐5D‐5L (r = 0.61 p = 0.005) and between PSP‐RS and ESS (r 0.35 p = 0.004). The SEADL and PSP‐RS were negatively correlated (r‐0.39 p = 0.002). Conclusion Consistent with apriori hypotheses we found anxiety, depression and PSP‐RS are related to function as measured by the SEADL and quality of life of PSP patients. Sleep disturbance was related to PSP‐RS. These results emphasize the importance of comprehensive evaluations to better capture the multi‐faceted impairments seen in PSP that have a meaningful impact on the patient’s life.

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.
