I have a touch of what I call "Parkinson's brain".  It's been acting up lately.  I can't remember things!  It's really frustrating.  Losing my short-term memory was one of my first Parkinson's symptoms.  It's worse on days when I'm tired, or when I'm stressed.

I've found this wonderful on-line brain trainer.  I play it at least three times a day. I highly recommend it even if you don't have Parkinson's!  it's called "Lumosity" and it's an app.  You can get their iPad/iPhone version called "Brain Trainer".  Check it out!  www.lumosity.com.
