New studies are emerging dealing with the issue of self-identity and brain injury. Many traumatic brain injuries result in a victim’s inability to identify people around him, or even remember things about his own self. A small group of brain scientists is now investigating misidentification syndromes, as the delusions are called, for clues to one of most confounding problems in brain science: identity. How and where does the brain maintain the “self”? I have watched my brain injury clients struggle with this same phenomenon, and hope studies like this one continue to increase the chances of other treatments for axonal injury and its consequences.
