Metabolic dysregulation in Alzheimer's disease: A brain metabolomics approach.
Article in Alzheimer's & dementia : the journal of the Alzheimer's Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
introductionThis study aimed to identify specific biological pathways and molecules involved in Alzheimer's disease (AD) neuropathology.
methodsWe conducted cutting-edge high-resolution metabolomics profiling of 162 human frontal cortex samples from the Emory Alzheimer's Disease Research Center (ADRC) brain bank with comprehensive neuropathological evaluations.
resultsWe identified 155 unique metabolic features and 36 pathways associated with three well-established AD neuropathology markers. Of these, 18 novel metabolites were confirmed with level 1 evidence, implicating their involvement in amino acid metabolism, lipid metabolism, carbohydrate metabolism, nucleotide metabolism, and metabolism of cofactors and vitamins in AD neuropathology. Genetic variability influenced these associations, with non-carriers of the apolipoprotein E (APOE) ε4 allele showing stronger perturbations in metabolites including glucose and adenosine 5'-diphosphoribose. DISCUSSION: This study demonstrates the potential of high-resolution metabolomic profiling in brain tissues to elucidate molecular mechanisms underlying AD pathology. Our findings provide critical insights into metabolic dysregulation in AD and its interplay with genetic factors. HIGHLIGHTS: This is one of the largest untargeted metabolomics studies of human brain tissue. 155 metabolic features, and 36 metabolic pathways were linked to Alzheimer's disease (AD) neuropathology. Of these, 18 unique metabolites were confirmed with level 1 evidence. Glucose and adenosine 5'-diphosphoribose identified as key metabolic alterations in AD.
