Sometimes. There are several possible abnormalities on an eeg which can confirm the diagnosis of epilepsy, if the patient's history is consistent with that. However, some eegs may be "over-interpreted" as being consistent with seizures when they are not, so it is important to work a neurologist who has been trained in eeg interpretation. A seizure may be recorded during an eeg, that may be confirmatory.
Yes and no. The eeg is a tool to be used by a trained neurologist to help diagnose epilepsy. The eeg alone is of little value. The history and examination are the important elements. Eeg recorded during a seizure can be very helpful but difficult to obtain. Baseline eeg can show abnormal activity, especially in children, even though the patient has never had a seizure. It is valuable in the right hands.
Abnormal EEG means epilepsy, or are there other people with abnormal EEG but are perfectly fine, please help!?
Depends on setting. While there are people with abnormal eegs who do not have any symptoms, most eeg abnormalities do suggest an underlying problem. That being said, not all abnormalities are created equal- some may simply mean that the patient was sleep deprived, while others can signify constant ongoing seizure activity. A neurologist can help put the findings in the right context. Read more...
