Brain-training, when done right, can lower dementia risk.
Although many so-called brain-training products claim to keep minds sharper and stave off dementia, evidence in support has not been overwhelming. The latest analysis, however, finds that not all brain-training is equal.
There are many companies that offer computerized brain-training tools, many of which promise to keep older minds more agile for longer.
Individual companies claiming to provide health benefits without the backing of solid evidence has caused a pushback from scientists.
A group of experts from the Stanford Center on Longevity released a statement in 2014, which said:
"We object to the claim that brain games offer consumers a scientifically grounded avenue to reduce or reverse cognitive decline when there is no compelling scientific evidence to date that they do."
However, according to findings presented at the American Psychological Association's 124th Annual Convention this week, there is one type of training that does have the support of scientific evidence.
The results were presented by Jerri Edwards, Ph.D., of the University of South Florida, who says: "The mistake some people make is thinking that all brain-training is the same."
"Lumping all brain-training together is like trying to determine the effectiveness of antibiotics by looking at the universe of all pills, and including sugar pills and dietary supplements in that analysis. You'll find that some work and some do not.
To then conclude that brain-training does not work - or is not yet proven - is based on flawed analysis."

o, although studies, overall, are contradictory in their findings, Edwards believes that by throwing all training regimes into one pot, the results have been homogenized and become meaningless.
To rectify this knowledge gap, Edwards and her team carried out a systematic review and meta-analysis of more than 50 peer-reviewed scientific papers specifically looking at speed of processing training.
