Hello. I Started To Have Severe Headaches In Feb 2020
Fast forward to today, I sought a second opinion b/c I continue w/ headaches although not as bad, and my eeg report came back abnormal. The neurologist mentioned the possibility of epilepsy. I have had no seizures that I know off or had any common symptoms associated w/ seizures. The doctor scheduled me for a 24 hour eeg. He went over my results rather quickly so I would like further clarification.
My Symptoms: headaches, sometimes nausea, very lethargic.
-Can you explain the report and what outcomes this result could mean? Does it lean more toward a brain tumor or epilepsy?
-Do these readings mean that I was having a seizure at the time of test, or do the waves remain this way once you have had a seizure?
- Is it common to have a normal eeg and then an abnormal one in a short amount of time (7 months for me) ?
-If the 24 hour eeg comes back clear will that mean I’m ok or will I have to get monitored yearly because of this abnormal result?
-How does epilepsy look like on an mri?
-Should I get another mri w/ contrast to rule out a brain tumor and any other epilepsy concerns?
As I said previously I have had no noticeable symptoms that would indicate epilepsy. I have 3 kids and and my youngest is 1 and I do know of the complications of epilepsy and pregnancy which I had none of, so this abnormal result has me baffled.
I am attaching my mri report and and today’s eeg report . Thank you for your time.

CONDITIONS OF RECORDING: This 16 channel EEG is performed w/ patient awake.
DESCRIPTION: Electrocerebral activity consists of well modulated 9-10 Hz background activity that attenuates symmetrically w/ eye opening. Low-amplitude faster frequencies are seen frontally.
ABNORMAL POTENCIALS: See impression.
ELECTRCARDIOGRAM: A single EKG rhythm strip performed during recording reveals no significant arrhythmias.
IMPRESSION: This is an abnormal awake EEG. Intermittent slow theta activity at 5-6Hz is seen in bilateral frontotemporal regions which may suggest mild cerebral dysfunction. In addition intermittent sharply contoured waves are also seen in bilateral temporal regions which are suspicious for being epileptiform. A 24 hour EEG is recommended for more detailed evaluation.
Consider follow up study in one year, if clinically indicated.

HISTORY: R51 Headache/Facial Pain M54.81 Head/Neck Pain
CLINICAL HISTORY: 27-year-old female with new onset of headaches.
TECHNIQUE: Sagittal, coronal, and axial images of the brain were obtained with a 3 Tesla
MR scanner both before and after the uneventful administration of intravenous contrast (14
cc of Gadoterate Meglumine).
COMPARISON: A previous CT of the head dated 5/5/2020 was available for review.
FINDINGS: No hemorrhages or masses are demonstrated. No acute infarcts are demonstrated.
No regions of abnormal contrast enhancement are demonstrated. Midline structures are
normal in position and ventricles are normal in size. Flow is documented in the major
vessels.
The paranasal sinuses are clear.
IMPRESSION: Normal examination.

Don't worry about any tumor or brain lesions.
Detailed Answer:
Hello and welcome to the "Ask a Doctor" service.
I have read your query and the reports of the MRI and EEG that you provided.
First, since the MRI with contrast came back normal you should not be worried about any tumor or vascular malformation.
In cases of epilepsy/seizures, MRI may show sclerosis of the mesial temporal lobe or hippocampus, brain lesions, etc.
It is possible for the EEG to show abnormal brain function without experiencing seizures.
I think that you should be treated for the headaches and considering them as primary headaches (in other words without any underlying cause).
The 24 hour EEG will give the necessary information about the seizures also.
Hope you found the answer helpful.
Let me know if I can assist you further.

- So does this one abnormal result mean for a fact I could have epilepsy or could it be a fluke?
-Could moving during the test affect this result? Looking back I did move quite a bit.
-If the 24 hour test comes back normal could I safely say I have no epilepsy?
-If it comes back abnormal does it clearly mean epilepsy?

I would explain as follows.
Detailed Answer:
Welcome back.
First, you don't have epilepsy, there are only abnormal findings on the EEG.
It could be a temporary metabolic change, moving during the examination, etc. that may result in false-positive findings in the EEG.
If the 24 hour EEG will come back normal, you should not be worried.
Hope this helps.
Feel free to ask if you have further questions.

My report states “Intermittent slow theta activity at 5-6Hz is seen in bilateral frontotemporal regions which may suggest mild cerebral dysfunction”.
1)Is this slow activity relatable to suspected epileptic activity or is it a separate issue?
2)What exactly does this mean?
3)What could be a possible cause of this?
4)Could this result be altered by moving allot during test, stress or other factors?
I am attaching an article that mentions both slow theta waves/epileptiform charges just like in my case.
**Slow-growing tumors, such as meningiomas, are usually associated with focal slow activity that occurs more frequently in the theta range. Epileptiform discharges can coexist with focal slow activity produced by brain tumors, especially slow growth (the least destruction of the brain parenchyma with slow growth tumors increases the possibility of detection of epileptiform discharges)**
3) Does this sound like my case?
-if needed At what point would another mri be advisable?
4) Since I have no history of seizures, If the 24 hour test comes back with same kind of abnormalities, do doctors usually wait and monitor for a first seizure to occur or is treatment started right away regardless of an absent seizure history.
Thank you.

Your questions answered below.
Detailed Answer:
Hello again.
Meningioma is easily seen on the MRI, so it is not your case.
Slow focal theta activity in EEG may be linked to a number of underlying causes, that, besides tumors, include ischemia, epileptic activity, traumatic injury, malformation of the cortical development, neuro-degenerative conditions, focal brain infections, etc.
Movement is unlikely to be the cause but cannot be excluded entirely.
Slow theta activity in EEG means cerebral function impairment.
Hope this helps.
Greetings.
