Abstract

fetched live from OpenAlex

OBJECTIVE: Benzodiazepines (BZDs) have been reported to cause negative impacts on body stability and cognitive functions, which in turn could result in lethal incidents, including falls, especially in the elderly. This fact notwithstanding, no systematic trial has evaluated the feasibility and benefits of discontinuing BZD-derivative hypnotics in this population, which was addressed in this study. METHODS: In this 8-week open-label study, subjects aged ≥ 60 living in a nursing home who received BZD as a hypnotic were recruited. The BZD dose was tapered off over 3 weeks. The following assessments were performed 12 h post-dose at baseline and at endpoint: the Clinical Stabilometric Platform (CSP), the Critical Flicker Fusion Test (CFF), the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), and the Leeds Sleep Evaluation Questionnaire (LSEQ). RESULTS: Thirty subjects were enrolled (mean ± SD age = 79.1 ± 8.9 years, mean ± SD flurazepam equivalent BZD dose = 19.5 ± 10.9 mg/day). Psychiatric diagnoses (DSM-IV) of subjects were as follows: schizophrenia (n = 12), primary insomnia (n = 9), dementia (n = 7), and bipolar disorder (n = 2). In 26 completers, significant changes were found in a total length and a range of trunk motion with eyes closed. Significant improvements were also observed in the CFF and RBANS immediate memory, language, and attention index scores. Subjective worsening in sleep was not reported in those completers, assessed with the LSEQ. CONCLUSIONS: Our results suggest that discontinuation of BZD hypnotics is feasible in a majority of elderly persons and leads to an improvement in the stability of body and a recovery in cognitive functions during the daytime.

Not 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.
