Does brain training work?
The answer is most certainly yes!
A great deal of research has gone into creating programmes such as Posit (for older folk), Cogmed and my personal favourite Lumosity. Working on the basis of use it or lose it, a great many notable neuroscientists around the world have come up with fun games which are specifically designed to work on such mental attributes as processing speed, attention and working memory.
The great thing about Lumosity is that when viewing the individuals profile and history it is possible for an experienced observer to see weaknesses and progress being made in functions that are lateralised to the left or right side of the brain. Advice can then be given as to what then needs to be achieved to gain brain balance.
