I had a 6 month MRI recently which showed necrosis! That was such a relief. Over the past few months, I've had intermittent power surges to the brain. Sorry, but I don't know how best to describe it. At first it was occasionally but increased in frequency. However, with my history of grand mal seizures (x20+ years ago, still on antiseizure meds), I got a bit paranoid. Had an ambulatory EEG, which lasted ~48 hrs. Needless to say, I lost loads of sleep having to wear all of that garb, which made the symptoms worse. During the first 24 hrs, I diaried 10 events. The second 24 yrs - 37 events. The surges are extremely brief with no alteration in vision or consciousness at all. My family didn't know it was occurring until I told them. I was to have worn it another 24 hrs but declined knowing I would be constantly pressing the button on the monitor. Neuro said there was no electrical activity suggestive of seizures which was an extreme relief. It's the strangest thing. I can go days with no symptoms of this. I can tell you that fatigue and stress make it worse. Dr. M and my neuro said it's not a common side effect but some have noted it off and on for up to a few years. Well if that's the most I have to endure, I'm more than fine with it. Other than the brain zapping, I'm back to napping a little more. That comes and goes also. There again, I could attribute that to other things going on in life. But the way I look at it is....this too shall pass. Or at least it better!
