Brain implant could ease the effects of a traumatic injury years later

An implant that stimulates a region deep in the brain may boost cognitive function in people with traumatic brain injuries long after the incident occurred. This is based on the results of a small study, which was primarily carried out to assess the device’s safety, with further research required.
A major blow to the head, due to a car crash, for example, can result in a traumatic brain injury (TBI). In mild cases, this may temporarily affect someone’s brain cells, but in more severe incidents, the individual can have long-term emotional, physical, cognitive and behavioural impairments.
“One of the major problems is that there really are no effective therapies for traumatic brain injury,” says Jaimie Henderson at Stanford University in California.
