Brain Training

Hi,

Let's start off with a quote directly from a brain training site:
"Our online brain gym is a place where you can exercise your brain so you will be sharper at work, in school, and at home. You exercise by playing brain games. These games are all developed based on neuroscientific research. You can train these cognitive functions:

- Visual Perception
- Logic
- Processing Speed
- Memory
- Concentration"

This is directly from http://braingymmer.com


So basically this site helps you literally train your cognitive functions.. Do you guys think it really works? Could it help against Alzheimer? I've heard a lot of confirmed results. I feel like it's working for me but it could be placebo. How did it work out for you?
