“…Normal transients include infrequent temporal sharp waves and frontal sharp transients ("encoches frontales"). Abnormal transients include central, surface-negative sharp waves; central, surface-positive sharp waves; and frequent high-voltage temporal sharp waves (Cukier et al, 1972;Tharp, 1980;Blume and Dreyfus-Brisac, 1982;Kellaway and Hrachovy, 1982;Clancy and Tharp, 1984). When interictal sharp-wave discharges appear in the EEGs of adults and older children suspected of having seizures, they are commonly used as evidence to support a clinical diagnosis of epilepsy.…”

The clinical identification of neonatal seizures is critical for the recognition of brain dysfunction; however, diagnosis is often difficult because of the poorly organized and varied nature of these behaviors. Current classification systems are limited in their ability to communicate motor, autonomic, and electroencephalographic features of seizures precisely and to provide a basis for uniform effective diagnosis, therapy, and determination of prognosis. Recent investigations of neonates, utilizing bedside electroencephalographic/polygraphic/video monitoring techniques, have provided the basis for improved diagnosis and classification of seizures in the newborn. These studies have demonstrated that not all clinical phenomena currently considered to be seizures require electrocortical epileptiform activity for their initiation or elaboration. In addition, the specific clinical character of the phenomena considered to be seizures, the clinical state of the infant, and the character of the EEG indicate the probable pathophysiological mechanisms involved and suggest probable etiologies, prognosis, and therapy. Similarities between animal models that demonstrate reflex physiology and neonates with motor automatisms and tonic posturing suggest that these clinical behaviors may not be epileptic in origin but, rather, primitive movements of progression and posture mediated by brainstem mechanisms. Although not all clinical behaviors currently considered to be neonatal seizures may have similar pathophysiological mechanisms, they are clinically significant because they all indicate brain dysfunction.

“…Descriptions of EEG abnormalities have been based on different definitions of abnormality in the preterm neonates. Some have used a marker such as intraventricular hemorrhage to assume that the brain was abnormal (15)(16)(17)(18)(19)(20). Others used a risk score based on maternal and perinatal conditions, e.g., Prechtl's optimality score, to form normal and abnormal groups (21).…”

We describe the evolution of a simplified method for the interpretation of serial EEG in preterm neonates which was tested in a first sample and revised and improved in a second sample of preterm neonates. There were 185 EEGs in the first sample and 206 EEGs in the second sample. The interpretation of the EEGs was related to mental, motor and neurological outcome in late infancy. Serial EEG is an excellent indicator of brain function in the preterm neonate.

“…These transients were reported for many years as a marker of IVH [71][72][73] and were subsequently recognized to be a specific EEG marker of white matter injury in preterm infants [29][30][31][74][75][76][77][78] , with a higher frequency being related to a worse motor outcome [74] .…”

This review focuses on the role of electroencephalography (EEG) in monitoring abnormalities of preterm brain function. EEG features of the most common developmental brain injuries in preterm infants, including intraventricular haemorrhage, periventricular leukomalacia, and perinatal asphyxia, are described. We outline the most common EEG biomarkers associated with these injuries, namely seizures, positive rolandic sharp waves, EEG suppression/increased interburst intervals, mechanical delta brush activity, and other deformed EEG waveforms, asymmetries, and asynchronies. The increasing survival rate of preterm infants, in particular those that are very and extremely preterm, has led to a growing demand for a specific and shared characterization of the patterns related to adverse outcome in this unique population. This review includes abundant high-quality images of the EEG patterns seen in premature infants and will provide a valuable resource for everyone working in developmental neuroscience.
