I may not be the quickest around, but I can generally solve moderately hard mathematic problems in my head + try not to use the calculator, mental calculations keep the brain sharp. My coworkers regard me as a glutton for punishment in this regard, but my rate of mistakes is the same as theirs(using this method).
Several years ago, I was in a research study that was all about the brain’s function(on high and low blood sugars). Part of it involved using a driving simulator, but most of it involved 10 million arithmetic problems, color coordination, connect-the-dots, Suduku, and whatever else you can think of. It was during this time that I discovered that I absolutely cannot subtract (in increments of 9) backwards, when hypo. Adding, yeah, kinda, but not subtracting. Deeply intriguing. It was a pretty weird study to begin with, what with brain leads all over my scalp but what that might mean (whether certain parts of my brain activity shut down during a hypo) the researchers didn’t share with me. All I learned is, my sensitivity to insulin.(which promptly changed,2 weeks later..)
Yesterday, I got a new game for my Nintendo DS- Brain Age. Supposedly supposed to keep your brain young and sharp. Went through the first exercise, and this is what I got:
I’m in serious trouble, if this is really the mental acuity of my brain. 20 years from now= nursing home..
Aughhhhhhhh.(am I that hopeless?)The Brain Age "goal" is 20.
Sometimes when high, I get brain fog but that's generally when I'm really,really high.(like over 500) I think diabetes must be pickling my brain- on both hypos AND hypers, it certainly affects things.
