Brain training programs and apps are very popular, thanks to their promise of being a convenient way to improve your thinking and memory. But how do you know they actually work?
Researchers from Edith Cowan University in Western Australia have reviewed the scientific evidence to find out which brain training programs can help prevent cognitive decline, such as due to Alzheimer's disease. Less than 40% of the programs they examined had any evidence to back them up.
The programs that seem to work are often designed to use neuroplasticity. This is the process the brain uses to make new connections, and it is also used to recover from damage due to a stroke.
Although the research doesn't directly relate to stroke rehabilitation, Dr Tejal Shah, who is one of the scientists involved, makes some recommendations of what to look for when choosing a brain training program.
One recommendation is to go to the program's website to see if any studies have been done on whether that specific brain training program works for the purpose you need, which may be improving your memory, reasoning, or processing speed.
In our enableme podcast on neuroplasticity, we asked Dr Michelle McDonnell from the University of South Australia about whether brain training apps are useful for stroke recovery.
"Neuroplasticity has to be specific, so you have to train what you want to get better," Dr McDonnell said. "So brain training apps for memory might work, if you want to improve your recall of phone numbers and names. But that probably won't transfer to things like speeding up your thinking or your ability to put things together.
"However, there is also research being done on Alzheimer’s disease and other forms of dementia on combining brain training with exercise for added benefit for learning and memory skills. So physical activity might promote neuroplasticity and improve your mood, as well as keeping you healthy and helping to prevent another stroke."
