Seizure incidence after deep brain stimulation: a meta-analysis of risk factors and target-specific outcomes in non-epileptic disorders.
Synthesis in Neurosurgical review, 2025. 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
introductionThe reports of seizures following Deep Brain Stimulation (DBS) are low; however, these seizures would be debilitating. Current literature has not provided a comprehensive analysis of seizure incidence post-DBS across various neuropsychiatric disorders. Additionally, there is a lack of insight into the contributing factors and the underlying mechanisms associated with this occurrence.
aimThis systematic review and meta-analysis investigated the incidence of epilepsy in patients with neurological disorders who have undergone DBS, excluding those with drug-resistant epilepsy. METHOD AND MATERIAL: The study was conducted according to PRISMA guidelines and involved thorough data extraction from several databases, specifically PubMed, Scopus, Embase, Web of Science, and the Cochrane Library, until 28-Feb-2025. We performed this Meta-analysis by using Comprehensive meta-analysis (CMA) software version 3.0 for the statistical analysis Results: This systematic review and meta-analysis encompassed 33 studies, and 5,488 patients. The most frequently neurological disorder which underwent DBS in this review, was Parkinson's Disease. Our meta-analysis revealed that the incidence of seizures following DBS was 2.9% (95% CI: 0.020 to 0.042; p-value < 0.001). A strong positive correlation was identified between the rate of intracerebral hemorrhage (ICH) and seizure occurrence, with a Pearson correlation coefficient of 0.635 (p-value: 0.007). Furthermore, there is a significant increase in the likelihood of seizure occurrences following globus pallidus internus- DBS compared to subthalamic nucleus- DBS.
conclusionPatients with neurological disorders following DBS may experience seizures; however, the incidence of such occurrences is low and typically resolves spontaneously.
