Inherited Prion Disease with a 5-octapeptide Repeat Insertion in the PRNP Gene Presenting with Familial Juvenile Dementia.
Article in Internal medicine (Tokyo, Japan), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled 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.
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
A 47-year-old man with a family history of juvenile dementia in his mother presented with memory loss and cognitive decline. Neuropsychological tests revealed impaired orientation, working memory, and apraxia. Magnetic resonance imaging revealed diffuse brain atrophy, and fluorodeoxyglucose positron emission tomography (PET) showed hypometabolism in the bilateral parietal lobes, posterior cingulate gyri, and precuneus, suggestive of Alzheimer's disease. However, amyloid-beta and tau PET scans were negative. Genetic testing revealed an abnormal repeat insertion in the prion protein gene, confirming inherited prion disease. This case highlights the need to consider inherited prion disease in the differential diagnosis of early-onset familial dementia.
