Are there any connections between ms and seizure disorders?

Yes: People with MS have a higher incidence of developing epilepsy over time. They are partial-onset seizures which can generalize into convulsions in some cases

Seizures and MS: About 2% of people with MS may have a seizure during their lifetime. This is slightly more frequent than people without MS. So yes, there is a connection. Anything that irritates the brain may cause a seizure. It is surprising people with MS do not have seizures more often.

Maybe: If you have MS, there is a 7-8% incidence of epileptic seizures. But the reverse is NOT true, as epilepsy otherwise does NOT relate to MS.
