I have the exact balance and memory issues. Just 5 minutes ago I was walking from the parking lot and "listing" to the left. It is always to the left for me, don't know what that means, but it is consistent. I also sometimes have difficulty remembering words and/or names. I was introducing my staff to a large group and I actually couldn't come up with a name (of my own staff member!). I'm getting good at covering up - and when I asked my husband if he notices, he said no.
Good luck to you - and just know, you are not alone! We deal with whatever cards are dealt to us, and attitude seems to be key.
