Robot-Based Cognitive Intervention Effects on Brain Function and Cognition in Patients With Mild Alzheimer's Disease Dementia.
Article in Psychiatry investigation, 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
objectiveCognitive interventions (CIs) are recognized for enhancing cognition and mitigating cognitive decline in dementia patients. Our study assessed the effects of a 12-week, home-based, robot-assisted CI on cognition and brain function in patients with mild Alzheimer's disease (AD) dementia.
methodsIn this single-blind randomized controlled trial, 51 patients with mild AD dementia were assigned to either a robot-assisted CI group (n=27) or a waitlist control group (n=24). The CI was conducted for 60 minutes per day over 12 weeks. The primary outcome was brain function, measured by resting-state electroencephalogram (EEG) using a 19-channel wireless EEG device and the secondary outcome was cognitive function, measured using the Cambridge Neuropsychological Test Automated Battery. No significant baseline demographic or clinical differences were observed between the groups. Eighteen participants in the robot group and 19 in the control group completed the study.
resultsEEG analysis revealed a decrease in theta band activity in the mid-frontal area for the robot group, while the control group exhibited an increase in this area. In addition, the robot group showed significant cognitive improvements in working memory, visual association memory, and reaction time after the 12-week CIs.
conclusionThese findings suggest that robot-assisted CIs may be associated with enhanced cognitive and brain function in patients with mild AD dementia.
