Epilepsy for 10 years. Recent EEG showed slowing of brain.

Epilepsy for 10 years. Recent EEG showed slowing of brain.

by cbillenste, May 15, 2006 12:00AM
I have been diaganosed with Epilepsy for 10 yrs. After seizure episode that left me in hospital for 3 days, EEG shwoed slowing of the brain.  When I question my neurologist he said that this was typical for my seizure condition. Since this is 1st I have heard of this I am somewhat concerned.

I am a 47 yr old female. On 800mg Neurontin 3x day, 100mg Topamax 2x day. Also have VNS implant in 2002. Have both grand mal and absence seizures 3-4 times a month. Also have constant headaches that are sometimes debiliatating. I have vision problems, syncope and low blood sugar (36). They also put a pacemaker in 2000 because during my seizures my heart rate would drop below 40 also causing me to pass out.

No one can say why i deveoped the seizures late in life. I think it was due to a surgery when my blood pressure and heart rate dropped so low ( this was during a mascetomy for breast cancer). The seizures developed after the surgery.

My question is, should I be concerned about the slowing in the brain or is this a typical part of seizure disorders? I am very fustrated with my doctor that this is the first I am hearing about it.

thank you.

Slowing on the EEG is quite common after a seizure and is called "post-ictal slowing". This occurs because after a seizure the brain is somewhat 'exhausted', and the brainwaves in teh are of the seizure will appear to be slower for a transient time. Usually this lasts for up to a few hours, but depending on the severity of the seizure up to a day or more. It does not mean that the brain is slow in between seizures. To obtain a proper look at the brianwaves in between seizures it should be done not around the time of a seizure.



In patients who have had a stroke or brain tumor etc there may be persistent slowing even in between seizures, usually only in one part of the brain.



Good luck

Which waves were slowed?   Delta, Theta, etc...

I had slowing on several EEG's and was told this was due to a structural lesion (it doesn't show up on my MRI's altho other lesions do).  I have read that it can be part of epilepsy.



Have you ever had a TTT (tilt table test)?  To see if you had convulsive syncope?  Or a Reveal ILR?



I had been thoroughly tested for this as I do have neurocardiogenic syncope (heart rate and bp drops) and I seem to have developed seizures too.  So, they wanted to be sure it wasn't all from the syncope (convulsive syncope).



Here is a link about the Reveal and sorting the diagnosis:

I'm not sure which waves were affected. My appt. isn't until 7/26.

Yes, I have taken & failed several tilt table tests. Also a MRI has shown 1 lesion.

by jan, May 15, 2006 12:00AM
If you failed the TTT did they look further into that to make sure your seizures weren't from that?  Did you have a concomitant EEG?  I am just asking.  You can have both conditions and yet the one can mock the other.

by cbillenste, May 16, 2006 12:00AM
no, my seizures are caused by epilepsy. I have had them while sleeping or sitting. You are right about the tilt results. The pacemaker has helped greatly with that.

by cbillenste, May 23, 2006 12:00AM
I also failed to mention that in addition to the seizures & headaches I have been experiencing chronic leg pain. It seems to move but there is a some tingling and numbness also. Aslo have some foot dragging and stumbling.

I had a concussion when I was in my early 20's. I am experiencing memory loss and general personality change.

Any help would be appreciated.
