I keep having feelings like my brain is actually short circuiting or something. I have dizzy spells like I'm falling. My husband and my youngest son say that at times I just "space out" and I don't remember doing it. I found out earlier this year that I have a carotid artery that is 100% blocked. I have no blockage anywhere else but my doctors can't tell me what's happening to me or why I had this blockage occur in the first place. This is starting to interfere with my life, please anyone help.

Have they treated the blocked artery???
Have you been tested for epilepsy???
What medications are you on?

It almost sounds like you might be experiencing TIA's or epileptic seizures, but my recomendation is to see a Neurologist ASAP
