While most seizures in newborns are due to acute brain injuries, a significant minority are caused by genetic epilepsies, which require distinct clinical management. Advances in genetic testing have clarified the major etiologic categories, including channelopathies, synaptopathies, inborn errors of metabolism, and brain malformations. Bedside clinicians must be alert to a possible genetic epilepsy in a newborn with seizures, as precise diagnosis informs prognosis and directly guides therapy. Sodium channel blockers can improve seizure control in specific channelopathies, vitamin therapies are effective in certain metabolic epilepsies, dietary therapy is transformative in glucose transporter deficiency syndrome, and targeted approaches are emerging for tuberous sclerosis complex. Rapid exome and genome sequencing now enable timely diagnosis in critically ill neonates and support precision treatment. Even with improvements in seizure control, developmental outcomes often remain poor, underscoring the urgent need for disease-modifying therapies. In conclusion, early recognition of epilepsies in the neonatal intensive care unit is essential to optimize care today and to accelerate the development of future targeted treatments.</div></div>","PeriodicalId":21761,"journal":{"name":"Seminars in perinatology","volume":"49 8","pages":"Article 152146"},"PeriodicalIF":3.2,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145102971","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}

Between these modalities, conventional MRI provides the optimal image resolution and detail about the developing brain, while advanced MRI techniques allow for the evaluation of tissue microstructure and functional networks. Over the last two decades, medical imaging techniques using brain MRI have rapidly progressed, and these advances have facilitated high-quality extraction of quantitative features as well as the implementation of novel devices for use in neurological disorders. Major advancements encompass the use of low-field dedicated MRI systems within the NICU and trials of ultralow-field portable MRI systems at the bedside. Additionally, higher-field magnets are utilized to enhance image quality, and ultrafast brain MRI is employed to decrease image acquisition time. Furthermore, the implementation of advanced MRI sequences, the application of machine learning algorithms, multimodal neuroimaging techniques, motion correction techniques, and novel modalities are used to visualize pathologies that are not visible to the human eye.

While most of those conditions are rare, many of the identified alterations involve common biological pathways and organ systems - particularly those affecting energy metabolism or the function of cells and organs of high energy demand such as brain, heart, and skeletal muscle - as well as genetic epilepsies.
