Dopamine System Dysfunction in Alzheimer's Disease.
Review in Psychogeriatrics : the official journal of the Japanese Psychogeriatric Society, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The dopaminergic system may be at the base of some neurobehavioral symptoms, as apathy and depression, and extrapyramidal symptoms, often seen in Alzheimer's disease patients. It can also have an impact on cognitive decline, as extrapyramidal symptoms, classically linked with dopamine dysfunction, are associated with increased risk of cognitive impairment and Alzheimer's disease progression. We review the knowledge of the dopaminergic system, emphasizing changes in Alzheimer's disease. Both animal models, post-mortem and in vivo human studies, point to a dopaminergic system dysfunction in this disease. Dopamine dysfunction seems more associated with neuronal loss, modification of dopamine receptors and anomalies in terminal function, including irregularities in dopamine metabolism, than with neurofibrillary tangles or β-amyloid plaques depositions. This dysfunction has an impact on both cognitive and non-cognitive symptoms. A better understanding of the dopaminergic system may help in understanding the pathophysiology of Alzheimer's disease and assist in the diagnosis. Clinical trials aimed at modulating the dopaminergic system may be promising in the treatment of symptoms associated with Alzheimer's disease.
