Hello. I m a 38 year old female diagnosed with Connective Tissue Disorder/Lupus. One symptom that is stumping my primary and neurologist is I have episodes of cognitive impairment. Just as quickly as if someone turned off the light switch, something happens where I feel my brain functions slow down, accompanied by sweating, slow speech. Had normal EEG. I also had an EKG recently that showed an extra heart beat (when I feel flutters ), and RBBB, but the docs say this is normal. I just had an episode occur while at a routine visit with my primary. Blood Sugar was 97 (I tend to have hypoglycemic events, which is why she checked). We were having a great conversation and I felt really good until this episode occured, suddenly. Any suggestions on what could be causing these episodes, that I can talk with my doc about?
