The difference is what EMS want. Most will not hire you, unless you can prove 3-5 years of no seizures. Does not matter if your seizure have been under control for a year or two. Have you ever heard of break through seizures. They happen whether you are properly medicated or not. That is something that you must deal with.
There is a reason why most systems will not hire someone with Epilepsy. How would you feel or deal with the liability if you had a seizure while treating a pt? Now ask that same question, if you were driving? How are you going to deal with having a seizure and crashing the ambulance, while running L&S. You now just killed your partner and pt! Can you see why there is the concerns involved.
Diabetics are different. They can control and monitor their BGL. There is a way of having that warning ahead of time. There is no warning with a seizure, except for those that might have auroras, seconds before.
I will tell you this from experience. I had a partner that never revealed his epilepsy. He had a seizure while driving to a call. Put the truck into a building. Luckily it was on way to call and I was up front with a seatbelt on. If I was in the back, I would have been killed. When we questioned him about his seizures, he stated that they had been under control for years. He also stated that he knew he would not get hired, if he told the truth. So, because he felt the need to not disclose his condition, he almost killed both of us.
On the flip side. I work with a IDDM every day. He checks his BGL every hour, while on shift. I keep an eye on him for changes in his mental status. This is something that can be controlled.
I would take the suggestions of looking at a different career path. Emergency nursing can be an exciting career, if that is what you are looking for!
I do not want to come off sounding mean, just giving you the facts of life.
