Computerized tomography (CT), electroencephalography (EEG), and clinical symptoms in severe cranio-cerebral injuries: A comparative study.

In the first six months of 1977 156 patients with craniocerebral injuries underwent computerized tomography. Twelve had severe deficits which led to neurosurgical interventions. Only five had space-occupying haematomas. CT was useful in detecting neurosurgical complications, whereas EEG was useful in staging the severity of the trauma. The two methods, the functional one of EEG and the morphological one of CT, are complementary, especially with regard to the posttraumatic course. The clinical symptoms are reflected by EEG better than by CT.
