Semiological differences of functional seizures between pediatrics and adults: video electroencephalography analysis.
Article in Acta epileptologica, 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
backgroundDiagnosing functional seizures can be challenging, and the semiology may vary between pediatric and adult age groups. Identifying those variabilities may be of diagnostic value. This study aimed to compare the semiological characteristics of functional seizures in both the pediatric and adult populations.
methodsAll video ictal electroencephalogram (EEG) recordings at Cairo University Epilepsy Unit (CUEU) from January 2021 to December 2023 were retrospectively reviewed for adults or children with functional seizures. Detailed semiological characteristics of the ictal events were analyzed independently by at least two epileptologists. Each event was listed under the classification system as either major motor, minor motor, dialeptic, non-epileptic aura, or mixed type.
resultsA total of 54 pediatric and 65 adult video ictal EEG studies were evaluated. Minor motor type was the most common clinical semiology among adult and pediatric groups, yet more prevalent in pediatric than adult patients (61.1% vs. 40.0%, P = 0.022). In comparison, the major motor events were significantly higher in adults than in pediatrics (25 event [38.5%] vs. 9 events [16.7%], P = 0.009). No statistically significant differences were found between pediatrics and adults regarding pelvic thrusting (3.7% vs. 9.2%), back arching (7.4% vs. 4.6%), clenched fists (9.3% vs. 15.4%), ictal pain (13.0% vs. 18.5%), ictal fear (5.6% vs. 3.1%), or ictal crying (7.4% vs. 4.6%), respectively.
conclusionsThe semiology of functional seizures varies between pediatric and adult age groups; minor motor events predominate in pediatric patients, while the major motor type is more common in adults.
