Actually it looks like it's part of a research project out of University College London. It sounds like it doesn't currently detect dementia, but will provide data that helps scientists turn it into a more diagnostic tool:
'This video game could help doctors diagnose dementia'

"Step one is establishing this live database of how do people navigate...that gives us the tool to develop that diagnostic," said Spiers. The team imagine a future scenario in which people suffering from dementia can be identified early -- by playing the game -- and trialed on relevant drugs to stop the disease taking full hold of their mind.
I like the idea of a game that will move us forward and will download that
It's also on Android.
