Non-invasive brain stimulation in frontotemporal dementia: syndrome-specific signals and priorities for future trials.
Review in Frontiers in aging neuroscience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Frontotemporal dementia is the second most common cause of young-onset dementia after Alzheimer's disease and lacks disease-modifying treatment. This narrative review summarizes human studies of non-invasive brain stimulation, including repetitive transcranial magnetic stimulation and theta-burst stimulation, transcranial electrical stimulation, and transcranial photobiomodulation, in frontotemporal dementia and primary progressive aphasia. We review stimulation targets, protocols, outcomes, and safety, and organize the evidence by clinical subtype and modality. Current data remain preliminary, but recurrent signals support prefrontal and cerebellar repetitive transcranial magnetic stimulation/theta-burst stimulation and prefrontal or temporoparietal transcranial direct current stimulation, particularly in primary progressive aphasia. By contrast, controlled evidence in behavioral-variant frontotemporal dementia is limited and heterogeneous. Future trials should be sham-controlled, multicenter, and syndrome-stratified; combine stimulation with symptom-relevant cognitive or language therapy; and incorporate biomarker-informed targeting, target-engagement measures, and longer follow-up to determine durability and clinical relevance.
