Patterns of Daily Administration of Psychoactive Drug Classes for Distress Behavior in Dementia.
Article in Journal of the American Medical Directors Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesDistress behaviors in dementia (DBDs) are common, are a significant burden to patients, families, and caregivers, and decrease quality of life. Despite risks, many nursing home (NH) residents are prescribed ≥ 1 classes of psychoactive medications for DBD. The objective of this study was to examine daily use of 4 classes of psychoactive medication in NH residents with DBD.
designThis was a retrospective longitudinal cohort study. SETTING AND
participantsParticipants included long-stay Veterans Affairs NH residents with dementia in 2019-2020, with and without DBD.
methodsWe identified daily use of antipsychotics, benzodiazepines, antidepressants, and antiepileptics, identified from bar-coded administration data, from 30 days prior to 30 days after a documented DBD incident. We estimated multivariate associations between resident characteristics and administration of selected classes of medication on the DBD incident day, accounting for prior class use.
resultsThe DBD and comparison groups consisted of 974 and 1138 individuals, respectively. Overall, the groups were 76 years old on average, and 14% had severe cognitive impairment. Administration of antipsychotic and benzodiazepine medication rose slightly 3 to 7 days before the DBD incident day, followed by sharp rises in administration on the DBD incident day, and sharp declines the next day. Increases in both classes persisted 30 days after the DBD incident day. None of these changes were observed in the comparison group. There were associations between benzodiazepine and antipsychotic administration and mental health conditions, and an inverse association between benzodiazepine administration and recent past gabapentin receipt. CONCLUSIONS AND IMPLICATIONS: Patterns of psychoactive medication administration varied among drug classes, but were linked across drug classes. Efforts to reduce prescribing of these medications need to be designed to take into account multiple classes of medication and target early signs of distress behavior.
