Traumatic brain injuries come in many forms, from a mild concussion caused by playing football to a blow in a violent car crash that leads to unconsciousness and memory loss. These injuries can be difficult to treat without causing undesirable side effects, but a new technology may help doctors deliver helpful drugs to specific areas of the brain without invasive techniques.
About 2.5 million Americans experience traumatic brain injuries every year, and unfortunately, the initial injury cannot be repaired. On the other hand, the damaging effects that follow, such as inflammation, high levels of free radicals, and signaling difficulties that could lead to cell death, can be minimized. There are more than 100 compounds in preclinical tests for lessening brain damage after injury. Delivering them to the damaged areas, however, isn’t an easy task.
