In brief: Utility of the EEG

An EEG measures the brain waves.
If one is obtained during a seizure, they are diagnostic for seizure. This is much better than seeing a seizure with our eyes. The EEG is also helpful for monitoring brain activity during sleep and alertness, coma and confusion.

In brief: FAIRLY ACCURATE

Eeg recorded over the scalp can help confirm or disconfirm seizure activity.
Sometimes, an eeg needs to be continuous, either ambulatory over a few days, or within a hospital observational unit for a few days, as, on occasion the activity may be missed otherwise. However, the eeg is not always perfect, and a doctor may diagnose epilepsy even with a normal eeg ee.
