Epilepsy in older adults: a comparison of early-onset persistent and late-onset epilepsy.
Article in Journal of neurology, 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
backgroundIn a globally ageing population, epilepsy in older adults has gained increased clinical relevance. This includes both individuals who have grown old with epilepsy and those who develop epilepsy later in life. Whether seizure outcomes and treatment patterns differ between these groups remains insufficiently characterised.
methodsIn this retrospective study, we included patients aged ≥ 65 years treated at three outpatient epilepsy clinics in Berlin between 2010 and 2025. Patients were categorised according to age at epilepsy onset. Early-onset persistent epilepsy (EOPE) was defined as onset < 40 years, and late-onset epilepsy (LOE) as onset ≥ 65 years. The primary endpoint was seizure freedom during the last 12 months. Secondary endpoints included markers of antiseizure medication burden, adverse effects and quality of life.
resultsA total of 243 patients were included (114 EOPE, 129 LOE). Seizure freedom was less frequent in EOPE compared to LOE (50.0% vs. 69.0%, p = 0.003). Patients with EOPE had a significantly higher drug load (median defined daily dose 1.00 vs. 0.67; p < 0.001). EOPE was independently associated with, among other variables, lower odds of seizure freedom (adjusted odds ratio (adjOR) 0.34, 95%CI 0.16-0.71) and more frequent use of first- or second-generation ASM (adjOR 5.99, 95%CI 2.47-14.54). The latter finding remained robust in a sensitivity analysis restricted to seizure-free patients.
conclusionsIn older adults, EOPE and LOE are associated with differing clinical characteristics. Patients with EOPE show lower seizure freedom and higher treatment burden as compared to LOE. In seizure-free patients with long-standing epilepsy, ASM simplification may be considered.
