Case Report: Acute hallucinations and delusions following an argument, attributed to temporal lobe hypoperfusion.

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
Purpose: Hallucinations and paranoid delusions are common psychiatric symptoms that can lead to dangerous behaviors such as self-harm and aggression. The temporal lobe is a key region for emotional processing, and its impairment can cause symptoms such as anxiety, depression, cognitive deficits, hallucinations, and delusions. The main purpose of this article is to discuss the effect of improved hypoperfusion on one patient's psychiatric symptoms. Patient and Methods: A 61-year-old male with untreated hypertension was transferred from the neurology department after developing hallucinations and persecutory delusions following a domestic argument. Perfusion-weighted magnetic resonance imaging (PWI) showed hypoperfusion in the temporal lobe. Results: Fluid therapy was immediately initiated to improve temporal lobe perfusion, and a low dose of anti-psychotic medication was maintained for a short time. After eight days of fluid therapy, the patient's hallucinations and delusions had substantially improved. A subsequent PWI revealed a marked improvement in both the relative cerebral blood flow and relative cerebral blood volume in the left temporal lobe. After discharge, anti-psychotic medications were stopped after one month. No recurrence of psychiatric symptoms was observed during a subsequent five-year monitoring period. Conclusion: The initial appearance of psychiatric symptoms requires vigilance for an underlying organic cause. Emotional agitation can cause insufficient cerebral perfusion in stenotic vessels, and hypoperfusion of the left temporal lobe may present as hallucinations or delusions. PWI and similar methods can help to differentiate organic brain disease from primary psychiatric disorders, and early restoration of cerebral blood flow often correlates with a good prognosis.
