Need Info Evoked Potential Test - Multiple Sclerosis Message Board

Being sent back to the Cleveland Clinic for a visual evoked potential and a somasensory potential of right leg and arm.

My general neurologist basically said he couldn't help me anymore.Just happened to be that the Neuromuscular specialist I was referred to called to give me my last 2 blood test results.Ruled out Lupus and Reuynalds syndrome.
After explaining my appointment with my ex-neurologist she has scheduled these test.What are they? What is normal or abnormal.I was really shocked when she said they were going to do the rt ankle.There's no reflex and the foot is completly numb.I can understand the vision,I just got new glasses in January and now they are not strong enough.At least the bi-focals aren't.After my last flair up the vision has not restored itself.See eye Doc tomorrow.Any in sight would be helpful.

visual evoked potentials are cake.. they just attach these little electronic sensors to your head and have you look at a TV screen with different patterns and record the results of (i think) your eye movement and reaction time? ( someone correct me if i am wrong).. no pain or anything... but the sticky suff they use to attach the sensors is kind of annoying to get out of your hair after..

i have no idea about the other test you mentioned, never had it done..

Thanks,They got me in at 8 am tomorrow.Usually it takes at least 3 weeks at the Cleveland Clinic for any test.

Toni, they are both Evoked potentials. The right side stuff is to test CNS funtion from your extremities. Both (SSEP and VEP) test brain signals received from your eyes and extremities (how long it takes for the signal to register in your brain and such).
Toni, you may get a dx today!

Thanks, had test and the specialist will call within a week with results.The vep test got half way through and the tech stopped and ask if I had numbness,tingling,muscle spasms,fatigue and what meds I took and sent me across the hall for the ssep.Which was a little painful.Tech said to relax there was to much muscle activity going on,chronic muscle spasms will cause this.Even took meds before hand.
Another wait and see.
