Periodic catatonia in the elderly: A case series highlighting the diagnostic challenge between delirium and catatonia.
Article in Industrial psychiatry journal. 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
Differentiating catatonia from delirium in elderly patients presents significant diagnostic challenges due to overlapping clinical features. This case series describes three elderly patients with periodic catatonia characterized by alternating states of stupor and agitation. Specific features, such as negativism and refusal to eat, were pivotal in distinguishing catatonia from delirium. Febrile episodes in these cases appeared to exacerbate symptoms, suggesting a potential role for systemic inflammation and cortico-striato-thalamo-cortical (CSTC) circuit dysfunction in the pathophysiology. Treatment with benzodiazepines and electroconvulsive therapy yielded positive outcomes, emphasizing the importance of early recognition and targeted intervention. Emerging evidence supporting the role of neuroinflammation and CSTC disruptions underscores the need for further research on biomarkers, neuroimaging, and novel therapeutic strategies to improve diagnostic accuracy and clinical outcomes in elderly patients with catatonia.
