Seizures in the newborn are associated with high morbidity and mortality, making their detection and treatment critical. Seizure activity in neonates is often clinically obscured, such that detection of seizures is particularly challenging. Amplitude-integrated EEG is a technique for simplified EEG monitoring that has found an increasing clinical application in neonatal intensive care. Its main value lies in the relative simplicity of interpretation, allowing nonspecialist members of the care team to engage in real-time detection of electrographic seizures. Nevertheless, to avoiding misdiagnosing rhythmic artifacts as seizures, it is necessary to recognize the electrophysiological ictal pattern in the conventional EEG trace available in current devices. The aim of this paper is to discuss the electrophysiological basis of the differentiation of epileptic seizures and extracranial artifacts to avoid misdiagnosis with amplitude-integrated EEG devices.

Background: Type A aortic dissection (TAAD) remains a significant challenge in cardiac surgery, presenting high risks of adverse outcomes such as permanent neurological dysfunction and mortality despite advances in medical technology and surgical techniques. This study investigates the use of quantitative electroencephalography (QEEG) to monitor and predict neurological outcomes during the perioperative period in TAAD patients.
Methods: This prospective observational study was conducted at the hospital, involving patients undergoing TAAD surgery from February 2022 to January 2023.

Background Hemimegalencephaly (HME) is a rare congenital disorder that is initiated during embryonic development with abnormal growth of one hemisphere. Tuberous sclerosis complex (TSC), a genetic disorder, is rarely associated with HME. Methods We present a case of a newborn with HME with a confirmed mutation in the TSC-1 gene and describe the clinical course, findings on (amplitude integrated) electroencephalography (aEEG), cranial ultrasound (CUS), MRI, and the postmortem evaluation.

Background: Hypoxic-ischemic encephalopathy (HIE) is still associated with death and sequelae including cerebral palsy and intellectual disability despite induced hypothermia. Biomarkers, as early predictive indicators of adverse outcomes, are lacking.
Aims: To investigate whether post-rewarming cerebrospinal fluid (CSF)-neuro-specific enolase (NSE) levels after hypothermia are associated with neurodevelopmental outcomes at age six years, alone or when combined with amplitude-integrated electroencephalography (aEEG) and brain magnetic resonance imaging (MRI), as neuroimaging and neurophysiological indicators, respectively.

Introduction: This study aimed to investigate the associations among seizures, clinical characteristics, and brain injury on Magnetic Resonance Imaging (MRI) in infants with Hypoxic Ischemic Encephalopathy (HIE), and to determine whether these findings can predict unfavorable neurodevelopmental outcomes.
Method: Clinical and electrographic seizures were assessed by amplitude-integrated electroencephalogram, and the extent of brain injury was evaluated by using MRI. At 12‒24 months of age, developmental impairment or death was assessed.

Article Synopsis
- Amplitude-integrated electroencephalogram (aEEG) is a tool for continuous monitoring of brain function in preterm infants and may help predict their neurodevelopmental outcomes.
- A systematic review of 19 studies involving 2074 preterm neonates showed that specific aEEG patterns, such as burst suppression and low voltage backgrounds, are linked to poorer outcomes, while normal backgrounds predict better development.
- Early monitoring of aEEG, particularly within the first week of life, is crucial for accurately assessing the neurodevelopmental prognosis of preterm infants.
