1 · What the graph read from it

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.

2 · The registry

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

While deep brain stimulation (DBS) is well-established for managing motor symptoms in Parkinson's disease (PD) and improving patient's quality of life, its impact on cognition is still not properly addressed. Cognitive impairment in PD often affects verbal fluency, attention, and executive functions, and may interact with disease progression, dopaminergic medication, and stimulation parameters. These outcomes are shaped not only by the stimulation itself but also by factors such as baseline cognitive status, lead location, disease heterogeneity, and parameter selection. The emerging development of closed-loop DBS (CL-DBS) offers a promising tailored neuromodulation strategy that may help reduce DBS side effects while enhancing non-motor function. Given the extensive yet heterogeneous literature on cognitive outcomes after STN-DBS, this review integrates mechanistic insights from human and animal studies to clarify how stimulation parameters, anatomical targeting, and network-level dynamics influence postoperative cognitive trajectories. We summarize established cognitive effects of conventional DBS, emphasize sources of interindividual variability, and evaluate how adaptive stimulation paradigms may modulate cognitive and decision-making processes. Finally, we outline translational considerations for biomarker development and personalized neuromodulation strategies aimed at preserving cognition while maintaining motor benefit.
