It is bad enough to have Multiple Sclerosis but sometimes this disease is associated with having other health disorders.  Some MS patients, for example, will have a seizure disorder in addition to having MS.  The Mayo Clinic reports that:

"Epileptic seizures occur more frequently in people with multiple sclerosis (MS) than in the general population. A 2003 overview of research indicates a seizure prevalence of 2.3 percent in adults with multiple sclerosis. In the general population (those who don't have MS), the seizure prevalence is approximately 0.4 percent to 0.8 percent." 

 So while this is not a huge percentage, it is far greater than would be for people who do not have MS.

Last summer I was showing some unusual symptoms which troubled a friend of mine.  My friend happens to have three children who all have epilepsy so when she saw me staring into space and "convulsing" she wondered if I was having a seizure.  I didn't think it could be a seizure as I was coherent and conscious the entire time.  But then she told me that there are many different types of seizures and some where the person does not lose consciousness.

Here is a more exact description of what would happen. I would get a sick feeling in my stomach and/or see a visual aura.  The visual aura looked like zig-zaggy lines resembling shards of a mirror.  They would start from my periphery, usually on my right side, and grow to a huge half a circle around my head.  The lines would appear to be shimmery and this would block my vision on that side.  In researching this aura I found that people with migraines and epilepsy often see this.  I have never had a migraine in my life and I didn't think I had epilepsy yet here I was with this symptom.

I would feel altered and dizzy and I always knew something was coming.  Then my right side would begin to convulse with my muscles of my legs and arms and even my back tighten followed by a shuddering release.  I could feel some sort of energy pulling my limbs to do this. The entire cycle would last between 20-30 minutes.

When I told my doctor about this during a physical, he thought it would be a good idea to have an EEG just to make sure that this was an MS symptom and nothing else.

An EEG is totally non-invasive and it does not hurt in any way.  This test is not to be confused with Electroconvulsive Shock Treatment for example.  You will not feel electrical currents or anything of that nature. An EEG is a simply a test which measures the electrical activity of your brain.  They look at your brain waves as recorded on a computer to see if there are any abnormalities in the patterns they see.

An EEG is primarily used to identify seizure disorders but it is important to know that an EEG in and of itself may not diagnose or rule out seizure disorders or epilepsy.  They always have to take other factors into consideration.
