New-Onset Psychosis Associated With Acute Cerebral Hemorrhage: A Case Report.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Psychosis is a disorder marked by altered perceptions and thoughts, and is traditionally associated with psychiatric conditions, but its occurrence in the context of organic brain lesions remains under-explored. This case report describes a 36-year-old African American female who presented with a unique psychiatric profile, characterized by subconscious somatic symptoms and delusions, which coincided with imaging findings of a subarachnoid hemorrhage. The alignment between the psychiatric symptoms and the site of the hemorrhage is highly unusual and suggests a direct link between brain injury and psychotic manifestation. While post-stroke or lesion-related psychosis often lacks such precise lateralization, this case stands out for its diagnostic implications. The somatic delusions and hallucinations observed, particularly those associated with the left frontal lobe and insular cortex, further support a neuroanatomical contribution to the psychotic symptoms. Although somatic delusions have been documented in patients with brain lesions, their lateralization is not well understood, and this case provides a rare opportunity to explore the role of specific brain regions in their development. To our knowledge, this may be one of the first instances in which psychotic symptoms localize ipsilaterally to a subarachnoid hemorrhage. This case highlights the complex relationship between neurobiology, neuroanatomy, and psychiatric symptoms, underscoring the need to consider organic brain lesions in the differential diagnosis of new-onset psychosis. Given the paucity of literature on this subject, this report calls for further investigation into how brain bleeds and other organic lesions contribute to psychiatric symptoms, with the aim of improving diagnostic accuracy and early intervention strategies. Understanding these associations may help clinicians refine their diagnostic approach and enhance patient care in cases where psychiatric and neurological symptoms overlap.
