Pseudobulbar Affect Among Patients With Dementia.
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
objectiveDementia is a neurocognitive disorder characterized by memory loss and deficits in multiple cognitive domains, caused by damage to or loss of neurons in the brain, which impairs one's abilities and capabilities for independent daily living. The etiologies of dementia are diverse, including vascular, infectious, traumatic, and neurodegenerative causes. The most common types of dementia include Alzheimer's dementia, vascular dementia, Lewy body dementia, and frontotemporal dementia. Patients with dementia frequently develop cognitive, psycho-behavioral, emotional, and mood symptoms. One largely unstudied mood symptom seen in dementia patients is pseudobulbar affect (PBA). PBA is a state of emotional incontinence characterized by episodes of uncontrolled crying or laughter that are inconsistent with the social context or the patient's emotional state. Although many neurological disorders may present with PBA, only a small fraction of the literature focuses on PBA in dementia patients. In the present study, we used the TriNetX database to identify a cohort of patients with both PBA and dementia. We describe this cohort to provide a foundation for further research on this patient population.
resultsSeventy-three percent (n=182) of the cohort had postconcussion syndrome, 18% (n=44) had overt dementia, 49% (n=121) had mild cognitive impairment, and 42% (n=105) had some form of amnesia. Many patients had comorbid psychiatric disorders, including anxiety and depressive disorders.
conclusionsThe multitude of comorbid mood disorders and symptoms can complicate the clinical management of dementia patients, adding to their distress and that of their caregivers. Understanding these symptoms is essential for providing an accurate diagnosis and effective management of PBA in dementia.
