Study shows video games could cut dementia risk in seniors

There was no significant difference in risk of dementia for the strategy-based memory or reasoning training groups.

Does that mean no significant difference between these two groups or no significant difference between either of these groups and the control (do nothing at all) group? (Lazy minds want to know.)

I'd like to personally thank JT for it's coverage of dementia/alzheimers.

It's really good to see any such development that may have a bearing on how the disease can be prevented/treated.

Thank you, again.
