Effects of Naltrexone on Cognition in a Treatment Study of Patients with Schizophrenia and Comorbid Alcohol Dependence
Bibliographic record
Abstract
ABSTRACT Deficits in frontal lobe functioning are common to both schizophrenia and alcohol dependence and have been associated with problems with memory and attention. Objectives: The first objective of this study was to examine the effect of naltrexone treatment on cognition in patients with schizophrenia and comorbid alcohol dependence. The second objective was to assess whether changes in drinking patterns were related to changes in cognitive functioning. Methods: Outpatients with schizophrenia and alcohol dependence (n = 30) were randomized (double-blind) to either naltrexone or placebo for 12 weeks to treat their alcohol dependence. After the initial 12 weeks of treatment they were offered the option of open-label naltrexone for an additional 12 weeks (8 patients continued on naltrexone, and 6 switched from placebo to naltrexone). Alcohol use, symptoms of schizophrenia, memory and attention were assessed at baseline, at week 12 and week 24. Results: The results showed that naltrexone had no effect on cognitive functioning for patients with alcohol dependence and schizophrenia, and there was no relationship between change in alcohol consumption and change in cognitive functioning in patients with alcohol dependence and schizophrenia. Conclusions: Naltrexone can be used safely for alcohol reduction in patients with schizophrenia and comorbid alcohol dependence.

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.
