Identification and diagnosis of ultra-rapid progressive dementia: evidence from a prospective cohort study and systematic literature review.
Synthesis in Journal of neurology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
BACKGROUND AND
objectivesThe term rapid progressive dementia (RPD) may be applied to patients who develop dementia within 1 year or complete incapacitation within 2 years of the first symptom of impairment. However, in select cases, cognitive impairment may emerge abruptly, with symptoms evolving across hours or days. We sought to determine the frequency, etiologies, and factors that associated with ultra-RPD.
methodsUltra-RPD was defined as persistent dementia (global Clinical Dementia Rating
resultsThree of 188 patients with RPD enrolled in our prospective series met the proposed definition for ultra-RPD (frequency = 1.6%). Systematic review yielded 57 additional cases from 47 publications (60 total cases). Ultra-RPD was attributed to vascular (40%), toxic/metabolic (22%), autoimmune/inflammatory (20%), and iatrogenic/structural (12%) causes. Lesions within the Papez circuit were detected in 52/59 (88%) of patients on neuroimaging. Twelve patients (20%) had potentially treatable causes of ultra-RPD. DISCUSSION: Patients with ultra-RPD were rarely encountered in our prospective series, representing < 2% of cases of RPD, and rarely reported in the extant literature. The evaluation of patients with ultra-RPD should prioritize testing for vascular, toxic/metabolic, and autoimmune/inflammatory conditions that affect neuroanatomical structures or networks critical for memory formation and retrieval.
