Low Frequency of Dementia with Lewy Bodies Diagnosis in a Colombian Memory Clinic.

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
backgroundThe global burden of dementia is increasing, particularly in low- and middle-income countries. Dementia with Lewy bodies (DLB) is the second most common neurodegenerative dementia but remains underreported and frequently misdiagnosed. Its prevalence in Latin America is largely unknown.
objectiveThe aim was to determine the frequency of DLB in a large memory clinic in Colombia and compare its clinical presentation with other neurodegenerative conditions, including Alzheimer's disease, frontotemporal dementia (FTD), vascular dementia, and Parkinson's disease dementia (PDD).
methodsWe conducted a retrospective study at a referral memory clinic in Bogotá, Colombia, from January 2018 to December 2022. DLB was identified based on the Fourth Consensus Report criteria. Random samples of patients with other neurodegenerative conditions were selected for comparison, maintaining a maximum ratio of 4:1. Clinical assessments were conducted by an interdisciplinary team using validated neurocognitive, neuropsychiatric, neuropsychological, and functional tools. Imaging and biofluid biomarkers were not available.
resultsOf 5518 patients, 38 (0.6%) were diagnosed with DLB. These individuals were predominantly male, with an average age of 72.3 years. Significant differences were observed between groups in age of onset, motor and cognitive function, and neuropsychiatric symptoms. Hallucinations were more common in DLB and PDD, whereas behavioral disturbances were frequent in FTD and DLB. Core symptoms of DLB were also present in patients diagnosed with other conditions, although cognitive fluctuations were not registered.
conclusionsDLB is likely underdiagnosed in this setting. Improved recognition and management are essential.
