Post-stroke cognitive impairment and fatigue in patients with white matter hyperintensities. A prospective cohort study.

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
Background: Cognitive impairment, depression, and fatigue are often neglected symptoms post-stroke. This study aimed to identify how white matter hyperintensity (WMH), a marker for cerebral small vessel disease (CSVD), is associated with post-stroke cognitive impairment, fatigue, and depression. Methods: This prospective cohort study included participants admitted with stroke or transient ischemic attack. Participants were classified into two groups based on WMH on magnetic resonance imaging (MRI) using the Fazekas scale (0-1: no CSVD, 2-3: CSVD). Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA), Symbol Digit Modalities Test (SDMT), and Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) in the acute stroke phase (≤14 days) and three months post-stroke. Fatigue and depression were evaluated with the Fatigue Severity Scale (FSS) and the Beck Depression Inventory-II (BDI-II). Results: Two hundred and fifty-six participants were included with MRI. A high Fazekas score was associated with lower baseline SDMT (-4.17 ± 1.48, Conclusion: These findings highlight the association between WMH, lower processing speed on the SDMT test in the acute stroke phase, and higher fatigue post-stroke. We propose that the WMH burden should be considered in all patients admitted with stroke or transient ischemic attack to identify those at increased risk of post-stroke cognitive impairment and fatigue.
