[Use and misuse of EEG].

Use and misuse of EEG Electroencephalogram (EEG) has an important role in the investigation of patients with different neurological disorders, especially epilepsy. Knowledge about the method, correct indications, its strength/weakness and the actual diagnosis is crucial to get the best out of EEG. The study of EEG-requests at a Swedish hospital during one year showed that 78% were consistent with guidelines and 86% of the acute requests were medically motivated or justifiable.
