Electrical sensations in brain

[simply1]

It's difficult to describe, but the past couple of years I've had this on and off for weeks at a time.

When I'm walking, or moving about in general, I get what feels like a shocking sensation, like a zap where
my visons goes out for a second, feel it through my whole head it seems.  At night I'll get severe "shocks" when falling asleep.  I am seeing a neurologist who has diagnosed this as a migraine condition, MRI returned normal.  I take lexapro for anxiety.  

Metoprolol seemed to subdue them, but the side effects were a bit tough on me as far as fatigue goes.  I could "feel" a spark start, but it wouldn't happen, an odd sensation.

That leads me to believe the diagnosis is correct, and I just need to find the right med (topamax is next up), but I'm also wanting to make sure this is right.  Should I go for a 2nd opinion somewhere and what sort of tests might I look for as I look for a higher end neurology department?  I like my neurologist, but it's a smaller hospital and I do have insurance with Mayo in Rochester, UNMC in omaha, Iowa University Hospitals, etc.

I should add I had a bout with transverse myelitis 11 years ago.

Wanted to let u know you are not alone.  I've had brain zaps and quakes for almost 3 years.  Docs look at me like I'm crazy when I try to explain the sensation.  

It can be a form of migraine from what I have read can also be a sx of withdrawl from an SSRI.

Ive have migraines for about 25 years.  Never like this before.  More recently it has been suggested that I have cluster headaches as well.

Wish u well finding the right med!

It is always good to go for second opinion when in doubt. Neurological conditions take time for picture perfect diagnosis. In migraine you have these black outs. With loss of blood supply even for a second to a region of the brain you might have these black outs!
You should follow up near your neurologist for further treatment and follow up and you have a choice to go for the 2nd opinion even if it is once, as you will be sure it is a migraine. Take care!
