Curbing the life-long effects of traumatic brain injury

A fall down the stairs, a car crash, a sports injury or an explosive blast can all cause traumatic brain injury (TBI). Patients often recover. But in the days or weeks following the hit, they can develop other serious, chronic conditions, such as depression and thinking and memory problems. Now scientists report a potential way to reduce these effects with a neuron-targeting nanoparticle, using an animal model of TBI.
