Results from VEP , EEG and EPT

Well, I just received my reports in the mail today.  I have not heard from the neuro yet, and not sure if he will call me or I have to call him.  2 out of the 4 tests were abnormal. Both my EEG and VEP were ABNORMAL.

EEG DESCRIPTION:

EEG Recorded during wakefulness and Stages I and II of sleep. Photic stimulation and hyperventilation both were performed.. Patient awake, there is a recognized posterior dominant rythm of 10 to 11 Hz frequency.

In the waking background, as well as during light sleep, occasional generalized polymorphic rhythmical activity is noted beginning at higher frequencies of 10 to 12 Hz with brief evolution to higher amplitudes of polymorphic slowing of 4 to 5 Hz frequency, with no definitive focus.  

Photic stimulation did not activate the recording.  Hyperventilation was associated with increased duration of the rhythmical episodes.

IMPRESSION:   Abnormal EEG due to Paroxysmal generalized polymorphic rhythmical slowing, consistent with cryptogenic generalized epilepsy.  No definitive epileptiform focus was identified.

VEP DESCRIPTION:

VEP study utilizing bilateral independent optic nerve stimulation of each eye with a black and white checkerboard pattern with a 15 degree angle check size yielded well formed P100 cortical wave forms bilaterally.

With stimulation of the left the latencies were 111.33 to 112.11ms, and with stimulation of the right eye were 125.39 to  127.34ms.  The absolute latencies of the P100 cortical forms with stimulation of the right eye were absolutely prolonged, and were also relatively prolonged compared to the P100 cortical latencies with stimulation of the left eye.

IMPRESSION:  ABNORMAL VEP study due to prolongation of the P100 cortical wave forms with stimulation of the right eye consisting with a demyelinating process involving the visual pathways from the right eye.

The somatosensory evoked potential of the upper and lower extremities were normal.

This neuro also stated that on examination day Jan. 7, 2011 I showed an equivocal Lhermitte's sign with neck flexion reflexes were brisk, and 2+ in arms. Tinel's signs are mildly positvie at the median wrists, equivocal at the ulnar grooves at the medial elbows, and negative at the ulnar wrists with negative Phalen's maneuvers and negative elbow flexion testing.

EMG testing, all normal.

Ok, so if anybody can translate this for me I would definately appreciate it.

Thanks and Hugs,
Pam

Thanks Bob!!! I wonder if I will get a phone  call tomorrow from the neuro.

I just sent you a note!!

If anyone else here has had this test done and would like to share, that would be great!!

I had the VEP done about a year ago.  95 mS in my left eye and 127 mS in my right eye.  The amplitudes were   I was diagnosed with Optic Neuritis and placed on a "watch list" for CIS.  

By Nov 2010 I had more periventricular lesions and was diagnosed.  I just had my third MRI last night. I'm waiting for it to be read.  I'm just finishing up my first 6 months on Copaxone.

Thank you for answering for me..... Yes, Everything has been tested, retested and retested again and no indication of anything else.
I was trying to read about VEP stuff and was not following too good, its easier for me when you break it down.
I did read something about the differences that show on the test about latencies and the fact that mine was absolutely prolonged it  does not fit my dx of ischemic optic neuropathy. It fits, Optic Neuritis.

Would you believe the dr. did not even call me? I probably should have called today but I assumed if he thought it was important to contact me he would have, right?

I have an appt. with my "regular neuro" on Monday and I don't even what to go, I haven't taken the klonopin he prescribed me, and the last time I was there, he disregarded my hand tremor as anxiety.  At this point, he is really going to  give me attitude when he finds out that I sought  out another opinion.

Have you had a VEP test done? I can't remember if you said you did, if so, did you have a description comparable to mine....? I know we can't compare, I am just curious about these numbers.

Thank you , thank you ,
Big Hugs,
Pam

Well, MS is one type of demyelinating process.  ADEM and Lyme's are others.  You don't fit ADEM and I think you said Lyme's had been ruled out.  If the only thing left is MS...

That is how the doctors are supposed to look at it when it is a diagnosis of exclusion.   They have the list of what to rule out.  When MS is all that remains...that it.

Bob-
Thanks, and with the statement of "consisting with demyelinating process", does he mean, it's possible that its caused from MS.?

Mary-
I hope these drsfinallydohelp Lol  As far as my Graves Disease and Eye Disease, I was dx'd with Ischemic Optic Neuropathy back in 07, however, I did have a change in my vision 6 months following my first eye surgery, and then it got alittle better 6 months later. I wasn't sure if it could have been I had my attack of ON during that time and it went unnoticed because of my Thyroid Eye Disease.

Dean-
I have had multiple issues with my eyes, Optic Nerve damage, nystagmus, diplopia, photosensitivity, wind sensitivity and unable to grasp at something, " like if  someone is holding a pen in their hand and I am trying to grab it" I miss it or think I am near it, but way off, it's funny and embarrassing at the same time.
I have a real hard time with depth perception, and I either raise my foot up high thinking I have to step up when the ground is even, or if there is a slope or something like that, I can't tell and I start walking like a drunk because the ground feels weird to me. It S U C K S !!

thanks you guys !!

And,, if anyone would like to share their numbers or results,, please do so, Thanks.

Hopefully your neuro will help you understand these results and help you! Best wishes. Just curious: with your abnormal VEP what symptoms or issues are you having with your eyes (or had at the time of the test)?

So, is there a way to know for sure what caused this ON?  I wonder if the neuro will know if it comes from the Graves (that's possible right?) or 'something else'.  Looks like you definitely have some findings to go forward with now.

It would seem the words I recently recycled from Lulu (without official permission) fit here as well, so ....  It is a strange place to be, right?  You've looked for answers and now that it appears you have them it is difficult to understand what it all means.

Hopefully a call or visit to the neuro will provide some answers.  Do you have another appointment?  I hope drsfinallywillhelp.

EEG shows slowing from multiple locations typically seen in epilepsy of an obscure or unknown form.

VEP shows decreased signal velocity from the right eye.  This is seen in Optic Neuritis

Tapping on the wrist showed mild entrapment of the median nerve (Carpel Tunnel) both wrists, but no evidence of ulnar nerve entrapment at the wrist.  It was neither positive nor negative with tapping at the elbow.  Manipulation of the elbow did not indicate ulnar nerve entrapment.

Is that what you were looking for?
