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.
