Brain games not all they're cracked up to be
Brain games may not be the key to protecting yourself against Alzheimer's, according to a study published in the journal Alzheimer's and Dementia
The study, commissioned by the US health body Lifespan, reviewed research from a number of studies undertaken since 1992 on the impact of brain exercises on older adults. The researchers concluded there was no evidence to prove that 'brain exercises' delay or slow cognitive decline in healthy older adults.
In recent years there has been a huge boom in the brain game market with companies like Nintendo producing hand held 'brain training' computer games designed to keep your brain sharp and in shape. This year Americans are expected to spend around $80 million (56 million) on brain exercise products compared with only $2 million in 2005.
While the exercises may not be damaging in themselves, the researchers are worried that older people may cut back on more active pursuits to spend time on games. "The brain ageing products sold today can be a financial drain, decrease participation in more proven effective lifestyle interventions, like exercise, and potentially undermine cognitive health by frustrating the 'worried well' if poorly designed," says lead author Peter J Snyder, professor of neurology at the Warren Alpert Medical School of Brown University.
The team note that some products have actually been marketed as weapons in the fight against Alzheimer's disease. However they admit that they were only able to find a very small number of studies rigorous enough to be included in the review and most of these lacked long-term follow-up. "More random clinical trials in cognitive training need to be conducted with sufficient follow-up time that can actually measure changes in daily functioning. Only in that way will we know if such exercises are effective in slowing the progress of mild cognitive impairment," conclude Snyder and his team.
Neil Hunt, Chief Executive of the Alzheimer's Society, welcomed the study but said that more research is needed before any solid conclusions can be drawn. "The jury is still out on whether brain games can help protect against dementia. We need to see a long-term, population-sized study - at the moment there is just not enough evidence either way," said Hunt. "However we do know that following a healthy lifestyle, including exercise and a balanced diet, can protect against Alzheimer's, so if you have an extra half hour we would recommend a good walk rather than staying in with a computer game."
