Abstract
ObjectivesCerebrovascular disease is the leading cause of seizures and incident epilepsy of known etiology in older adults. Statins have increasingly garnered attention as a potential preventive strategy due to their pleiotropic effects beyond lipid-lowering, which may include neuroprotective and anti-epileptogenic properties. We aim to assess the evidence on statin use for prevention of post-stroke early-onset seizures and post-stroke epilepsy. Materials and methodsWe conducted a systematic review and meta-analysis in accordance with PRISMA guidelines, which was prospectively registered with PROSPERO (CRD42019144916). PubMed and Embase were searched from database inception to 05/2020 for English-language, full-text studies examining the association between statin use in adults and development of early-onset seizures (≤7 days post-stroke) or post-stroke epilepsy. Pooled analyses were based on random-effects models using the inverse-variance method. ResultsOf 182 citations identified, 175 were excluded due to duplication or ineligibility. The 7 eligible publications were all cohort studies from East Asia or South America, with a total of 53,579 patients. Pre-stroke statin use was not associated with post-stroke epilepsy (3 studies pooled: OR 1.14, CI 0.91-1.42). However, post-stroke statin use was associated with lower risk of both early-onset seizures (3 studies pooled: OR 0.36, CI 0.25-0.53), and post-stroke epilepsy (6 studies pooled: OR 0.64, CI 0.46-0.88). ConclusionsReview of 7 cohort studies suggested post-stroke, but not pre-stroke, statin use may be associated with reduced risk of early-onset seizures and post-stroke epilepsy. Further research is warranted to validate these findings in broader populations and better parse the temporal components of the associations.
