A new study published today in the American Journal of Psychiatry can shed some light on this issue. Researchers at the Brain and Mind Centre at the University of Sydney, in Australia, reviewed more than twenty years worth of research on the effects of computerized cognitive training (CCT). They selected only randomized clinical studies, and used the statistical technique of meta-analysis to combine the results.
Their findings are surprisingly clear--for people with mild cognitive impairment, structured brain training can boost general thinking skills, attention, working or short-term memory, verbal long-term memory, learning and mood.
Mild cognitive impairment, or MCI, represents a kind of middle ground between the kinds of memory and other cognitive problems that occur with normal ageing and the more severe changes seen in Alzheimer's disease and other full-blown dementias. Typically about 10 percent of people diagnosed with MCI develop Alzheimer's or another form of dementia within a year.
In general, the kinds of computerized games and challenges studied did not help after people had already been diagnosed with dementia. Intriguingly, however, three studies that used more immersive technology such as Nintendo's Wii or virtual reality did show positive results even then--a lead well worth following.
Although emphasizing that further research is needed to see if the clear improvements caused by these cognitive exercise programs delay or perhaps in some cases prevent dementia, the researchers are encouraged. "Our research shows that brain training can maintain or even improve cognitive skills among older people at very high risk of cognitive decline," says neuroscientist Amit Lampit, who lead the study. "and it's an inexpensive and safe treatment."
With recent research also showing that structured physical exercises can also improve cognitive functioning in people with MCI (see my blog entry for 10/25/16), we can see the outline of safe and inexpensive interventions that may keep people's brains healthy and functioning well even as they age.
