Head trauma is the leading cause of morbidity and death in paediatric population. The authors present an outline of contemporary knowledge on the paediatric head injury on the ground of literature and own experience. The value of Glasgow Coma Scale, its modifications and other prognostic factors in children's population after head trauma is discussed. The management of mild head injury is also disputed. In conclusion it is stressed that since many differences in epidemiology, mechanism, pathophysiology and outcome of head injury in childhood and adults exist the separation of "paediatric neurotraumatology" is reasonable.
