Yes, I think I do. Been type 1 for 20 years, pumping 4 months. 59 years of age. There are times I feel somewhat light headed but not really. This especially when I am stressed. Too much thrown at me to process or trying to do too much. Concentration is sometimes an issue. This seems to happen when my blood sugar has been high for a while or changing rapidly from one extreme to the other. My wife have noticed my trouble with rememering things said or details with instructions. This is difficult to describe as there are no specific patterns here to put my finger on. Needless to say, this is quite frustrating at times. My diabetic Dr. does not think it is related to diabetes. I disagree with her. There are lots of other “signs” or “feelings” that tells me that my blood sugar has been too high or not in good control. Just had an MRI today to check things out to be safe. Any thoughts on this, anyone?
