Many of the mitochondrial epilepsies, particularly those presenting in childhood, are refractory to anti-epileptic treatment. Moreover, these conditions are typically characterised by severe neurodegeneration and closely associated with neurological decline and premature death. Indeed, there persists an urgent need to delineate the mechanisms underpinning mitochondrial epilepsy in order to develop effective treatments. In this review, we provide an overview of currently available in vitro models of the mitochondrial epilepsies. Such models offer opportunities to characterise early disease pathophysiology and interrogate novel mitochondrial-targeting and anti-epileptic treatments, with an overall aim to modulate seizure associated pathology and activity for the mitochondrial epilepsies. We discuss the use of acute cortical and subcortical brain slice preparations, obtained from both neurosurgical patients and rodents, for modelling the common neuropathophysiological features of mitochondrial epilepsy. We also review the use of induced pluripotent stem cell derived neural and glial culture models, and the development of three-dimensional cerebral organoids, generated from fibroblasts obtained from patients with primary mitochondrial disease. Human-derived, disease-relevant in vitro model systems which recapitulate the complexity and pathological features observed in patient brain tissues are crucial to help bridge the gap between animal models and patients living with mitochondrial epilepsy.</p>","PeriodicalId":49552,"journal":{"name":"Seizure-European Journal of Epilepsy","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144133155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

POMA was VEEG monitored in 73.7 % of the patients during both wakefulness and sleep, and 63.2 % (12/19) could be induced by hyperventilation (HV). Synchronized perioral electromyography confirmed that the ictal 3-Hz discharge was time-locked with the myoclonic jerks. Twelve patients underwent VEEG follow-up, with 66.7 % achieving seizure-free with valproate (VPA) monotherapy.

POMA tends to occur more frequently in males. 73.7 % of the patients had POMA during both wakefulness and sleep. The VEEG background is mostly normal, with rhythmic 3-Hz generalized spike and wave discharges during the ictal period that are time-locked with perioral myoclonia. Patients with POMA respond well to VPA. POMA may be misdiagnosed as focal seizures, but the use of OXC, CBZ, and phenytoin sodium for treatment should be avoided.</div></div>","PeriodicalId":49552,"journal":{"name":"Seizure-European Journal of Epilepsy","volume":"130 ","pages":"Pages 51-55"},"PeriodicalIF":2.7,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143934763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
