There is increasing evidence that infants with mild neonatal encephalopathy(NE) have significant risks of mortality, brain injury and adverse neurodevelopmental outcomes. In the era of therapeutic hypothermia, infants need to be diagnosed within 6 hours of birth, corresponding with the window of opportunity for treatment of moderate to severe NE, compared to the retrospective grading over 2 to 3 days, typically with imaging and formal electroencephalographic assessment in the pre-hypothermia era. This shift in diagnosis may have increased the apparent prevalence of brain damage and poor neurological outcomes seen in infants with mild NE in the era of hypothermia. Abnormal short term outcomes observed in infants with mild NE include seizures, abnormal neurologic examination at discharge, abnormal brain magnetic resonance imaging and difficulty feeding. At 2 to 3 years of age, mild NE has been associated with an increased risk of autism, language and cognitive deficits. There are no approved treatment strategies for these infants as they were not included in the initial randomized controlled trials for therapeutic hypothermia. However, there is already therapeutic creep, with many centers treating infants with mild NE despite the limited evidence for its safety and efficacy. The optimal duration of treatment and therapeutic window of opportunity for effective treatment need to be specifically established for mild NE as the evolution of injury is likely to be slower, based on preclinical data. Randomized controlled trials of therapeutic hypothermia for infants with mild NE are urgently required to establish the safety and efficacy of treatment. This review will examine the evidence for adverse outcomes after mild NE and dissect some of the challenges in developing therapeutic strategies for mild NE, before analyzing the evidence for therapeutic hypothermia and other strategies for treatment of these infants.

Besides local neuronal damage caused by the primary insult, central nervous system injuries may secondarily cause a progressive cascade of related events including brain edema, ischemia, oxida- tive stress, excitotoxicity, and dysregulation of calcium homeostasis. hypothermia is a beneficial strategy in a variety of acute central nervous system injuries. Mild hypothermia can treat high in- tracranial pressure following traumatic brain injuries in adults. It is a new treatment that increases survival and quality of life for patients suffering from ischemic insults such as cardiac arrest, stroke, and neurogenic fever following brain trauma. therapeutic hypothermia decreases free radical pro- duction, inflammation, excitotoxicity and intracranial pressure, and improves cerebral metabolism after traumatic brain injury and cerebral ischemia, thus protecting against central nervous system damage. Although a series of pathological and physiological changes as well as potential side ef- fects are observed during hypothermia treatment, it remains a potential therapeutic strategy for central nervous system injuries and deserves further study.

中枢神经系统损伤为包括脊髓损伤、创伤性脑损伤和卒中等在内的一系列损伤，它可导致明显而长期的功能障碍，给社会经济带来了极大的负担。原发性中枢神经系统损伤除导致局部的神经损伤外，还可导致包括缺血、脑水肿、兴奋性中毒、氧化应激和钙稳态调节异常等的继发性损伤。多年来的研究发现亚低温是一种对一系列中枢神经系统损伤有益的一种治疗方法。同时，轻度治疗性亚低温是一种对成人创伤性脑损伤伴颅内高压有效的治疗方法，是能增加遭受缺血性打击（如心脏骤停、卒中）病人和脑损伤后的神经源性发热病人的存活率、改善损伤后病人生活质量的一种新的治疗手段。研究发现，治疗性亚低温能减轻炎症、兴奋性中毒、自由基的产生和颅内压，并能改善创伤性脑损伤后和脑缺血后的脑代谢。同样，作为一种有效的治疗方法，治疗性亚低温常被用于减轻缺血缺氧导致的神经损伤，但其潜在的作用机制却仍不清楚。目前，在几个主要的治疗中心，治疗性亚低温常被用于动脉瘤夹闭术中的脑保护。

Background: Moderate to severe hypoxic-ischemic encephalopathy (HIE) in neonates is often treated with hypothermia. However, some neonates may experience epileptic seizures during therapeutic hypothermia (TH). Data on the electrophysiologic and evolutionary aspects of these seizures are scarce in African countries. Objectives: To determine the types of epileptic seizures caused by HIE in neonates in Brazzaville;to describe the evolution of background EEG activities during TH and rewarming;to report the evolution of epileptic seizures. Methods: This was a cross-sectional, descriptive study conducted from January 2020 to July 2022. It took place in Brazzaville in the Neonatology Department of the Blanche Gomez Mother and Child Hospital. It focused on term neonates suffering from moderate or severe HIE. They were treated with hypothermia combined with phenobarbital for 72 hours. Results: Among 36 neonates meeting inclusion criteria, there were 18 boys and 18 girls. Thirty-one (86.1%) neonates had grade 2 and 5 (13.9%) grade 3 HIE. In our neonates, HIE had induced isolated electrographic seizures (n = 11;30.6%), electroclinical seizures (n = 25;69.4%), and 6 types of background EEG activity. During TH and rewarming, there were 52.8% of patients with improved background EEG activity, 41.7% of patients with unchanged background EEG activity, and 5.5% of patients with worsened background EEG activity. At the end of rewarming, only 9 (25%) patients still had seizures. Conclusion: Isolated electrographic and electroclinical seizures are the only pathological entities found in our studied population. In neonates with moderate HIE, the applied therapeutic strategy positively influences the evolution of both seizures and background EEG activity. On the other hand, in neonates with severe HIE, the same therapeutic strategy is ineffective. .
