What are eeg and mri used for in evaluating seizures?
3 doctors weighed in across 2 answers
Function and structu: Eeg confirms whether or not there is a short circuit that could be detected in the brain to confirm whether you are having seizures. Many times, however, the short circuit is missed on routine eeg.If we are suspicious enough, sometimes we just treat. Mri helps to see if you can identify the cause of the short circuit. Such as an old stroke, scar tissue due to trauma or something more serious.

Find cause: Mri may reveal structural cause for seizures. Eeg may show seizures or spikes (electrical abnormalities highly associated with the clinical occurrence of seizures. Type of "spikes" on eeg may help determine the seizure type and whether there is a genetic basis of seizures.
