How accurate are eegs?
3 doctors weighed in across 2 answers
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.

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.
