Thank you all for your response. I am on a lot of meds: cardiac meds, Ritalin, SSRI, GI meds, etc... was on seizure med (Keppra) foe a whiie, too. I had an episode while hooked up to telemetry and EEG while in a epilepsy -monitoring-unit (for 4 days) and it showed no circulation to my brain while heart was OK. I also had many recorded seizures during surgeries and procedures that were monitored and witnessed. I keep being told that this very rare but I am sure there are others experiencing the same thing?
