Abstract

fetched live from OpenAlex

ABSTRACT This study investigates the effects of chronic use of benzodiazepines (BZ) as hypnotics on the neuropsychological performance of older adults with insomnia. Twenty-one older persons who had used BZ on a chronic basis (average duration = 21.7 years) for their sleep difficulties were enrolled in a medication withdrawal program. A neuropsychological evaluation was conducted before and after the taper program. A control group composed of older adults not using BZs and without sleep complaints were also evaluated for comparative purpose. The results showed that prolonged use of BZ produces mild and selective impairments of cognitive and psychomotor performance. However, BZ users subjectively evaluated their own performance much more negatively than good sleepers. The results are discussed in terms of a possible amplification of performance deficits among insomnia patients and also as a tolerance to adverse effects that develops with prolonged utilization of BZ.

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.
