Further studies have claimed that brain training improves the cognitive function of older adults, contributing to the growing body of evidence suggesting that the activity can help to stave off dementia.
Researchers from Japan presented their findings based on two studies at the Alzheimer's Disease International Conference.
Collectively the investigations involved 156 participants, 124 of which were older adults living in the community and 32 Alzheimer's patients in a nursing home.
In each study subjects were divided into two groups, with one taking part in brain training. In both studies those who engaged in the activity showed improvements in their cognitive function.
A spokesperson from the Alzheimer's Society stated: "The results are promising but more research is required in larger numbers of people and we need to see if it has benefits for everyday life."
The Alzheimer's Society is itself carrying out research into the benefits of brain training, but advocates staying active, eating well, not smoking and watching blood pressure and cholesterol to help stave off the disease.
