Effects of Transcranial Direct Current Stimulation on Graph Naming Function and Brain Connectivity in Postinfarction Aphasia Patients: An fMRI Study.
Article in Folia phoniatrica et logopaedica : official organ of the International Association of Logopedics and Phoniatrics (IALP), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
introductionThe study aimed to investigate the mechanisms of impairment and recovery in graph naming functions among patients with aphasia due to cerebral infarction. Specifically, the study compared immediate effects of transcranial direct current stimulation (tDCS) treatment in patients at different stages postinfarction: the acute phase (AP) and the recovery period (RP).
methodsTwenty-eight patients were selected, consisting of 16 in the AP and 12 in the RP, along with 18 healthy controls. Both patient groups underwent 2 weeks of tDCS treatment. Posttreatment changes in functional connectivity (FC) within language-related brain regions, as well as in graph naming abilities, were assessed in both patient groups.
resultsBoth AP and RP groups exhibited significant improvements in graph naming ability following tDCS treatment. Compared to healthy controls, patients showed decreased FC in multiple brain regions of both hemispheres, particularly in the dominant hemisphere. Posttreatment assessments revealed significant increases in FC within the bilateral frontotemporal lobes for both AP and RP groups, and within the bilateral temporo-occipital regions for the AP group. Moreover, the RP group demonstrated decreased FC in the left temporal lobe posttreatment, which had shown increased FC pre-treatment.
conclusionsThis study suggests that tDCS can effectively enhance graph naming functions in patients with postinfarction aphasia. The therapeutic effects appear to be mediated by enhancing FC within bilateral frontotemporal lobes.
