The Pentagon is exploring the development of implantable probes that may one day help reverse some memory loss caused by brain injury.

The goal of the project, still in early stages, is to treat some of the more than 280,000 troops who have suffered brain injuries since 2000, including in combat in Iraq and Afghanistan.

The Defense Advanced Research Projects Agency is focused on wounded veterans, though some research may benefit others such as seniors with dementia or athletes with brain injuries, said Geoff Ling, a physician and deputy director of Darpa’s Defense Sciences office. It’s still far from certain that such work will result in an anti-memory-loss device. Still, word of the project is creating excitement after more than a decade of failed attempts to develop drugs to treat brain injury and memory loss.
