Each person and each brain injury is different. A primary injury refers to the moment of impact, whereas secondary injury refers to complications from the primary injury. Issues such as cerebral edema, hypoxia, ischemia, or herniation are all considered secondary injuries. After the primary injury, preventing secondary injuries becomes the focus in emergency and intensive care units.
Types of problems, as well as length and amount of recovery, vary considerably from person to person depending on the location, type and extent of injury. Some problems affect many people while others seldom occur.
