Glymphatic activity in behavioral variant frontotemporal dementia: Link with vascular function and astrocytic activation.
Article in Alzheimer's & dementia : the journal of the Alzheimer's Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
introductionGlymphatic activity, vascular function, and astrocytic activation play pivotal roles in the pathophysiology of frontotemporal dementia (FTD). However, their interrelationships and combined impact on clinical features remain unclear.
methodsGlymphatic activity was measured by diffusion tensor image analysis along the perivascular space (DTI-ALPS) in patients with behavioral variant FTD (bvFTD, n = 61) and normal controls (NC, n = 61).
resultsGlymphatic activity in bvFTD correlated strongly with vascular dysfunction and astrocytic activation, and was associated with brain changes and clinical severity. Astrocytic activation mediates the association between vascular and glymphatic function. Astrocytic activation mediates the association between glymphatic function and clinical scales, whereas glymphatic function mediates the association between vascular function and clinical scales. The interaction effect was found between vascular function and glymphatic activity on white matter hyperintensity. DISCUSSION: Our findings reveal a complex interrelationship among glymphatic, vascular, and inflammatory mechanisms in FTD, highlighting their collective impact on disease severity. Highlight Vascular function, astrocytic activation, and glymphatic activity correlate with each other in frontotemporal dementia. Glymphatic activity mediates the association between vascular function and cognition. Astrocytic activation mediates the association between glymphatic function and cognition. Vascular and glymphatic function synergy drives white matter hyperintensity.
