“…EEG measures voltage fluctuations resulting from ionic current within the neurons of the brain. Because EPs and ERPs are generated by neuronal activity, they are valuable for assessing the integrity of neural processing capabilities in patients sustained TBI [ 27 ]. Derivatives of the EEG technique include EPs, which involves averaging the EEG activity time-locked to the presentation of a stimulus of some sort (visual, somatosensory, or auditory).…”

“…Both have the major prognostic value in TBI [ 25 , 26 ]. In TBI, these EPs patterns have high early prognostic value for any outcome [ 27 ]. Continuous EEG monitoring is used for diagnosis and treatment of non convulsive seizures and status epilepticus, whereas EPs are more able to indicate the emergence of neurological deterioration.…”

Traumatic brain injury (TBI) is one of the major causes of human mortality and morbidity in the world. Brain injury could affect the core of a person's being – their thinking, memory, personality and behaviour. Electrophysiological markers from the human electroencephalogram and brain imaging provide a rich source of data which helps to elucidate specific processing impairments in TBI patients. To assess the cognitive and social function in traumatic brain injury patients, this review will focus on some of methods for assessing the disabling cognitive and social function deficits induced by TBI. There are many new technologies available to address TBI and recognition related questions. Integration of the various techniques will help to facilitate our comprehending of TBI, cognitive function and social function, and improve treatment and rehabilitation.

“…Two prospective studies used passive ERP paradigms in children with DOC. One published by Schalamon et al 12 described the prognostic feature of somatosensory evoked potentials (SEPs) in 26 acute traumatic comatose children. They found a bilateral absence of SEP responses in 10 children that systematically predicted negative outcome (i.e.…”

The diagnosis and prognosis of disorders of consciousness (DOC) such as coma, unresponsive wakefulness syndrome, or minimally conscious state are especially challenging in children. In some paediatric patients with severe acquired brain injury, medical comorbidities or developmental factors may obscure the detection of signs of consciousness via clinical assessments, thus leading to misdiagnosis. To circumvent these biases, patients benefit from multimodal assessments that combine behavioural, neuroimaging, and neurophysiological measures. In this review, we provide original data for such diagnostic procedures in children. Neuroimaging is largely underdocumented in children and most neurophysiological research consists of a cohort study design aimed at providing prognostic markers for clinical outcomes. The scarcity of available data on complementary diagnostic approaches in children makes it difficult to establish clear paediatric guidelines. Although there is preliminary evidence for the applicability of paradigms involving event‐related potentials as support for diagnosis in children, more well‐designed studies need to be conducted to promote evidence‐based practices in paediatric DOC.

“…65,66 In addition, SEPs have been found to be better predictors of outcome than motor or pupillary responses. 67 Comparatively, in one study, 10% of children with acute severe TBI, with bilaterally absent SEPs, had favourable outcomes. 68 An important confound not mentioned in the above SEP studies was the routine exclusion of a peripheral neuropathy.…”

The diagnosis of mild traumatic brain injury in concussion is difficult since it is often unwitnessed, the patient's recall is unreliable and initial clinical examination is often unrevealing, correlating poorly with the extent of brain injury. At present, there are no objective biomarkers of mild traumatic brain injury in concussion. Thus, a sensitive gold standard test is required to enable the effective and safe triage of patients who present to the acute services. As well as triage, objective monitoring of patients' recovery over time and separate from clinical features that patients may develop following the injury (e.g. depression and migraine) is also needed. In contrast to neuroimaging, which is widely used to investigate traumatic brain injury patients, electrophysiology is readily available, is cheap and there are internationally recognized standardised methodologies. Herein, we review the existing literature on electrophysiological testing in concussion and mild traumatic brain injury; specifically, electroencephalogram, polysomnography, brainstem auditory evoked potentials, electro-and videonystagmography, vestibular evoked myogenic potentials, visually evoked potentials, somatosensory evoked potentials and transcranial magnetic stimulation.

Somatosensory evoked potentials in children with severe head trauma

Abstract: Measurement of somatosensory evoked potentials provides valuable data for determining the prognosis at early coma stages. Our data show that an unfavourable outcome can be predicted with higher precision than a favourable outcome.
