Medical Forum / Diseases and Disorders / Epilepsy / August 2004EEG Results
Hi All, I had posted my recent experience with a possible right TL seizure. Had an EEG done which came back with the results posted here. Turned out to be activity over both sides of the brain instead of just the right. Hope it's ok to post it. For entertainment purposes only! I find this stuff very fascinating. Does this look like anyone elses? Can one have left and right TLE? Been having these "experiences" for 5 years now. Told my mother about it, and she "encouraged" me to see a doctor so I am just now learning about this. Thanks for looking- Jennifer Waking background activities consist of low-amplitude, but very well-modulated 11 Hz alpha rhythms. These are often of slightly higher amplitude over the left hemisphere than the right. Hyperventilation is performed early on. The patient develops several discrete bursts of anterior predominant and at times high amplitude 3-4 Hz delta waves. These are only questionably of earlier onset over the left hemisphere than the right on 1 or 2 occasions; otherwise they appear synchronous. Small sharp forms are seen before the slow waves at times and at other times this activity appears somewhat notched. It seems best developed near the end of photic stimulation at clock time 09:046:56. Photic stimulation is next performed and results in a symmetrical photic driving response and no additional abnormalities. Eventually the patient falls into light sleep, which is punctuated by periods of arousal. No lateralized or focal waves are seen. No additional abnormal spike or sharp wave activities are seen nor are there any other paroxysmal abnormalities. Impression: Abnormal EEG because of rhythmic bursts of high amplitude slow activity, which is anterior predominant and probably synchronous over the two hemispheres, although at times there is a question of earlier onset on the left. Overall this is most likely to represent a generalized epileptiform discharge, but the pattern is not fully diagnostic. Clinical correlation would be quite important. The slight asymmetry in amplitude of background activity is of doubtful significance, but sometimes can be associated with structural disease or extracerebral fluid collections. If not already done, brain imaging is indicated. > Hi All, > I had posted my recent experience with a possible right TL seizure. > Had an EEG done which came back with the results posted here.

Hi It talks about "generalized". Did you have a grand mal seizure or are these partial seizures? > Does this look like anyone elses?

I have left and right TLE on the EEG myself although it really shows up predominately as right. > Thanks for looking- Jennifer > [quoted text clipped - 26 lines] > disease or extracerebral fluid collections.

It is important that you have the "brain imaging is indicated" taken care of with an MRI and a CT-Scan. In addition to what they mention there, any tumor or scar tissue would show up.

Thanks for including the report. It is interesting even though I don't understand half of it. > Does this look like anyone elses? I don't think they gave me a written report. > Can one have left and right TLE? I don't see why not. I mean, in theory you probably wouldn't expect the same problem on both sides, but maybe the causes are different, maybe the locations in the temporal lobes are different, and maybe the time the initiating factor kicked in is different.

But like Bob, I think it's worth having the more detailed tests (likely an MRI or CT scan). Those would show if there's any scar etc. down to fractions of a millimetre. Some types of szrs. can start in one (e.g.) Temporal lobe and generalize into the other. If they can identify where it starts, it makes choice of medications or treatments more accurate, and less trial and error. When you have onset do you get any e.g. Lemon or sour tastes or odours? or Eggy or Sulphury (sp?) type? The 'aura' of a Right T.Lobe is the first sensation sometimes, while the Left Temporal lobe Seizure Focus (start point) can produce the second one. (Part of above suggested that some of your's tended to be in Left side -***a above.) Also the Right side can produce feelings of Deja Vu (where you feel like you've said or done this already), while the Left side Temporal lobe seizure can produce a Jamais Vu (Never seen, where you feel lost or disoriented, even if you're at your own place). Those are non-invasive type symptoms that the Dr. might have asked you about already. Other parts of the brain produce other symptoms or sensations than those. Those examples are more specific to Temporal Lobe-based seizures (often listed within Complex Partial Seizures on newer sites).

Hello, You may want to subscribe to: http://home.ease.lsoft.com/archives/epilepsy-l.html Some epileptologists / MD's like Selim Benbadis are sometimes answering questions and can certainly interpret the stuff you just wrote / copied from that report.  SignatureTake care. Marco |
