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.© 2022 Mac Keith Press.
