1 · What the graph read from it

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.

2 · The registry

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

We describe a rare case of epilepsy-related PWD in the elderly. A 61-year-old right-handed man presented with status epilepticus. Although electroencephalogram revealed no epileptiform discharges, brain magnetic resonance imaging (MRI) showed hyperintensity in the left temporoparietal lobe and thalamic pulvinar on diffusion-weighted imaging (DWI). Cerebrospinal fluid revealed no pleocytosis and negative PCR results for herpes simplex virus and varicella-zoster virus. Following the recovery of consciousness, he exhibited a profound dissociation between auditory and speech/language modalities: he was unable to comprehend or repeat spoken language but could follow complex written instructions and fluently produce grammatically correct speech. He had largely preserved perception of non-verbal sounds. Despite minor accompanying oral reading deficits interpreted as concomitant symptoms of an extensive lesion, he was diagnosed with epilepsy-related PWD. Following the administration of levetiracetam, the patient's language function recovered significantly within 20 days. This case suggests that PWD represents an overlooked, transient manifestation of dementia-like symptoms in late-onset epilepsy. Due to its rapid reversibility, such cases are likely underrecognized and underreported; further documentation is warranted.
