Although games like sudoku, crosswords and online brain training games are largely believed to ward off the onset of dementia, there is no scientific evidence to suggest this a new survey has shown. 

If you reason with yourself that it's good for your health as you force yourself to unfurl the daily crossword each evening, unfortunately it looks like your actions may be in vain. 

It seems that while you may have made a crossword champion or sudoku master of yourself, it is unlikely that your efforts have influenced your chances of developing dementia at all.

"If people play a "brain game," they may get better at that game, but improvements in game performance have not yet been shown to convincingly result in improvements in people’s daily cognitive abilities.There is insufficient evidence that improvements in game performance will improve people’s overall functioning in everyday life", a survey by the Global Council on Brain Health reads. 

According to the survey's authors there is no evidence suggesting that improving your ability at sudoku will  help you in other areas like managing your finances.

Dementia remains an ever increasing cause of concern for Irish people.

According to a study entitled, The Prevalence of Dementia in Ireland, there are 48,000 people in Ireland alone with the illness.

This figure is expected to rise to 140,000 by 2041 - an increase of 240% on the 2006 figure. 

Speaking to RTÉ Lifestyle in January, Dr Sabina Brennan, Psychologist and Research Assistant Professor at Trinity College Dublin explained that we should tend to our brain with the same level of care we give our teeth.

"Everyone with a brain needs to consider brain health just as everyone with teeth needs to consider dental health" she explained. 

"Our brain is constantly changing and it's our behaviours and our experiences, the things that we do or don't do, that shape it and influence how well it functions and even how resilient it can be when faced with aging, injury or disease", she said.

For those who do want to take preventative steps, experts recommend eating a good diet, avoiding alcohol, exercising, interacting with others and monitoring blood pressure and cholesterol.
