Mapping striatal functional gradients and associated gene expression in Parkinson's disease with continuous cognitive impairment.
Article in NPJ Parkinson's disease, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
Cognitive impairment in Parkinson's disease is closely tied to striatal dysfunction, yet the neurobiological interface between macroscale connectivity and molecular signatures remains unexplored. This study characterizes striatal gradient organization and its genetic underpinnings across PD cognitive trajectories. We analyzed functional connectivity gradients in 126 PD patients (spanning the cognitive spectrum from normal cognition to dementia) and 40 healthy controls, correlating spatial patterns with neurotransmitter architecture and transcriptomic profiles. Three distinct striatal gradients emerged: Gradient 1 remains stable throughout disease progression and partially aligns with canonical striatal subdivisions. Gradient 2 represents a spatial continuum closely linked to dopaminergic innervation and becomes most pronounced in the dementia stage. Gradient 3 corresponds to cortico-striatal connectivity patterns implicated in both early and advanced cognitive deficits. Spatial transcriptomic and neuroimaging correlation analyses identified significant associations between cortico-striatal gradient disruptions and specific gene expression patterns. These findings provide valuable insights into striatal macro- and microstructural changes in PD and their role in cognitive impairment.
