Various methods for gauging traumatic brain injuries, or TBIs, are now available or in development—from high-tech CT scans and Diffusion Tensor Imaging to relatively low-tech cognitive tests that measure attention, memory, and decision-making. Some new technologies—visors and helmets—even make it possible to diagnose damage directly on a playing field or battlefield.
