This study followed survivors of brain injury and found that two years after brain injury, 85 percent of persons in this study remained married. Those at greater risk of marital instability included younger persons, males, having TBI from a violent injury, and having a moderately severe injury. Among people with more severe disabilities, the likelihood of remaining married was higher for minorities.
