Traumatic brain injury (TBI) is a medical-surgical emergency and a frequent reason for referral to emergency rooms and for hospitalization, particularly among young and elderly patients. It is a clinically heterogeneous condition, comprising mild to severe forms. Before the advent of imaging, electroencephalogram (EEG) was used in the first assessment of patients with acute TBI. Today, computed tomography and other neuroimaging techniques have substituted EEG as first-line investigations for the diagnosis of cerebral lesions following head trauma. However, EEG continues to have a relevant role in monitoring brain functional activity in patients with TBI and in detecting post-traumatic epileptogenic foci.
