For example, I have an excel column on my food diary/excel spreadsheet for the number of calf cramps I experience. It's a finite, objective number which can be tracked to see the effect of various diet & supplement hacks.
Is there a good way to quantify brain fog?
Presently, in narrative form, I record particularly glaring examples such as pressing the button for the wrong floor on the elevator. However, it doesn't do a good job of capturing and recording the overall level of mental sharpness.
I suspect there's an app for my ipad or android phone but I presume it's probably puzzle based games. I bet the longer you play at it, the better you get, so that might not be a good proxy for overall mental functioning.
All thoughts, comments or app suggestions are very much welcome.
