Prevalence of epilepsy and seizure history in Finnish neuropathologically examined medico-legal autopsy cases with acute head injuries.
Article in BMC research notes, 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
objectivesEpilepsy and traumatic brain injury have a bidirectional relationship. This study aimed to report the prevalences of antemortem epilepsy diagnosis, seizure history, epilepsy-related and traumatic neuropathological findings, as well as background characteristics, among neuropathologically examined medico-legal autopsy cases with acute head injuries.
resultsThe sample included 82 cases from Helsinki, Finland, from the years 2016-2022. Of the sample, 17 cases had an epilepsy diagnosis or documented seizure history ("Epilepsy/Seizure Group"), whereas 65 did not ("No Seizure Group"). The most frequent epilepsy-related neuropathological findings were hippocampal atrophy and mossy fibre sprouting. Of background characteristics, the Epilepsy/Seizure Group had a higher prevalence of old head injuries (41.2% vs. 7.7%) and chronic alcohol use (41.2% vs. 18.5%) than the No Seizure Group. There were no statistically significant differences in acute head injuries or secondary neuropathological findings, except for a lower prevalence of oedema in the Epilepsy/Seizure Group (17.6% vs. 47.7%). Even though the Epilepsy/Seizure Group had a higher prevalence of old head injuries and chronic alcohol use, the prevalences of acute head injuries were not higher. Larger studies are needed to further explore whether individuals with epilepsy or seizure history are susceptible to distinct head injury types or circumstances.
