A HIGH-tech device that could prevent memory loss in dementia patients is set to bring new hope to millions of sufferers.

cientists have developed an electronic implant to help brains damaged by Alzheimer's retain memories. 

They hope it will be used to take over certain areas of diseased brains to help "translate" a short-term memory into a permanent one. 

The implant has been developed at the University of Southern California and Wake Forest Baptist Medical Centre over a decade. 

The project is funded by the US military as a way of helping injured soldiers overcome memory loss.
