Movement disorder emergencies at a tertiary-care center in West Bengal, India: Spectrum, etiologies, diagnostic implications.
Article in Next research, 2026. 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
Background: Acute-onset movement disorders, often termed movement disorder emergencies, present in emergency and inpatient neurology settings and may arise from diverse causes, including potentially reversible metabolic and medication-related conditions. Objectives: We aimed to describe the clinical phenomenology and etiological spectrum of movement disorder emergencies presenting to a tertiary care center. Methods: We conducted a prospective, single-center, hospital-based cross-sectional observational study over 12 months (February 2023 to January 2024) at a tertiary-care hospital in Kolkata, Eastern India. Patients aged 12 years or older with a movement disorder onset within 4 weeks were enrolled. Movement disorder presentations were categorized as hyperkinetic, hypokinetic, or mixed. Results: Eighty patients were included (mean age 48.0 years, standard deviation 18.0; 57.5% male). Hyperkinetic presentations predominated (80.0%), followed by mixed (13.7%) and hypokinetic (6.2%) presentations. The most frequent phenomenologies were hemichorea and myoclonus (18.7% each), followed by acute parkinsonism (17.5%), dystonia (16.2%), and tremor (15.0%). Mean symptom duration at presentation did not differ across movement disorder categories (p = 0.36). The movement disorder category was not associated with sex (p = 0.68), age group (p = 0.39), or timing of presentation (p = 0.632). The leading etiologies were metabolic (26.2%) and drug-induced (25.0%), followed by vascular (15.0%), functional (8.7%), and infectious (6.2%) causes. Functional etiologies presented exclusively with hyperkinetic phenomenology. Conclusions: In this tertiary-care cohort, movement disorder emergencies were predominantly hyperkinetic, and metabolic and drug-induced causes accounted for over half of the cases. These findings support an expeditious diagnostic approach that prioritizes rapid metabolic screening, careful medication review, and targeted neuroimaging when clinically indicated.
