Memory is an issue I struggle with (and it's the measure my MS center uses to gauge general cognitive issues - GREAT) so I've been working on the "mind palace" technique to improve my rote memorization. I got "average" on their last assessment and freaked out - perils of being an adult who was a childhood good test taker (and moderate perfectionist). I know that's breaking the spirit of the assessment but I can't deal! Here's an article that I liked: https://www.nytimes.com/2016/03/24/upshot/an-ancient-and-proven-way-to-improve-memory-go-ahead-and-try-it.html

I was also doing Dual N Back a few years ago, and it was both fun and frustrating! I think it may have helped, though. Check that out here: http://brainscale.net/dual-n-back There are also good apps for it in the app store.

My husband is really into this stuff so we try a lot of different ones, these two have been his favorites though.
