Hi everyone. Yesterday I had a sleep deprived EEG test to check for seizures, and I wondered if what I experienced was normal or abnormal.. During the strobe light portion of the test, I was okay at first, but then my eyelids started fluttering/twitching even after the lights stopped flashing. I had no control over this. I also felt like I was going to pass out, but it was as if I couldn't even talk to tell the technician that I was having difficulties. Thankfully the strobe light portion of the test was over then. The part of the test where I had to breathe faster and deeper gave me a bad headache towards the end. The headache didn't last long after that, but I wondered if that was normal. Have any of you had similar reactions to the strobe test and the breathing test? I will be getting the results in less than a week, but I thought I'd ask on here in the meantime. Thanks in advance to any of you who respond.
