A researcher from the University of Southern California has demonstrated how a brain implant can be used to improve memory which could have a major effect on the treatment of dementia sufferers. Professor Dong Song implanted his device into 20 volunteers and collected data on their brain activity during memory tests to find the pattern of optimal memory performance. He then used the implanted devices electrodes to stimulate the brain based on this pattern.
The results found that this stimulation improved short-term memory by about 15% and working memory by about 25%. This research could be vital for people who suffer from Alzheimer’s. The proportion of people with this disease is growing rapidly as the world’s population ages and the financial and emotional costs associated are ballooning as well. If Song's device can help these people recover even part of the their memory it would be a big breakthrough in dementia treatment.
