Epileptiform discharges in presence of continuous background activity in anoxic coma.
The EEGs of a group of patients in anoxic coma following cardiorespiratory arrest were retrospectively studied. Twelve of 70 patients had at least one EEG recorded during the acute period which consisted of epileptiform discharges in the presence of continuous diffuse background activity. ⋯ The analysis confirms the prediction of a recent revision of EEG grades in coma that this particular pattern of activity is of uncertain prognostic significance. This is in contrast to the occurrence of epileptiform discharges during discontinuous "burst suppression" activity which generally indicates a fatal outcome.

Comparative StudyEEG vs. computerized tomography of brain in neurological diagnosis.
Computerized tomography and electroencephalography are emerging as the two main practical neurodiagnostic tests in the study of brain disease. The comparative advantage of each test is discussed from the point of view of possible outcomes and the results of the tests. A logistic scheme suggests how to use these tests to arrive, cost effectively, at the most accurate diagnosis.

Our experience with the use of EEG in the diagnosis and management of acute neuropsychiatric patients in the emergency room is reported. The importance of the role of EEG in the diagnosis of different types of seizure disorders, toxic-metabolic encephalopathies, acute psychoses, and head injuries is emphasized. In many conditions EEG may be the only diagnostic tool to help the physician to arrive at an accurate diagnosis and management of the patient. The cost efficiency is more practical than other more expensive and more customarily used tests such as CT Scan, and the information obtained cannot be reproduced by such other tests.
