I was dx with RRMS last year and my neuro started me on Keppra as I was suffering badly with myoclonic jerks. I was given a brain and spinal MRI as they suspected I has MS and not epilepsy but needed the proof.
The Keppra has helped a great deal, I no longer jump like mad and when I go to bed I actually manage to get some sleep, I used to sit down stairs in the wee hours jumping all over the place.
I still get them but not to the same severity, which is bliss.
It just made me wonder why anyone who still suffers with myoclonic jerks is not taking this particular drug.
