It's something I just discovered through everyday life, didn't take any formal tests. As far as dealing with it...nothing really solves the problem, nothing that I have discovered that is. I suppose keeping my condition in mind when it comes to having to remember something helps a bit.
One specific time I noticed the problem was in an anatomy class. I was in a small group and instructed to quickly memorize the name and location of certain muscles on the animal we were dissecting. Seems easy enough, and for everyone in the group it was, but it took me much longer and I still could not recall a few of them.
