What is PTA?
PTA stands for post traumatic amnesia. This is a period of confusion that follows the injury. It is normal for people to not remember the events that occurred right before or right after their injury. However, people differ with respect to how long the period of confusion lasts after injury. It may last for minutes, hours, days, or weeks. During PTA, people are usually unable to make new memories. They may be unable to remember what happened to them, where they are, or what they did a few minutes ago. One way to judge the severity of an injury is by how long the post-traumatic amnesia lasts. The longer the person is confused and not remembering information, the worse the injury.
