In the 1970s, awareness of TBI as a public health problem grew. A great deal of progress has been made since then in brain trauma research, such as the discovery of primary and secondary brain injury. The 1990s saw the development and dissemination of standardized guidelines for treatment of TBI, with protocols for a range of issues such as drugs and management of intracranial pressure. Research since the early 1990s has improved TBI survival. That decade was called the "Decade of the Brain" for advances made in brain research.
