<qa>  What is the name of the person who has suffered a head injury?Despite the bodys natural healing during the first year after a head injury, many veterans who have suffered even mild brain injuries find themselves easily upset or fearful as they go about their daily lives. While these reactions to the world around them were easily managed before the head injury, they now occur with little or no interruption and are exceedingly difficult to manage. Such reactions include a sense of always being upset or fearful that often makes it difficult to get along with family members, friends, coworkers, and employers. This may lead to broken marriages, unemployment, and even homelessness.
