A year after traumatic brain injuries, most patients are well enough to care for themselves. Unfortunately, some never fully recover from the symptoms that plague them immediately after the accident. Most patients develop complications that cause cognitive problems and behavioral inconsistencies, and these symptoms do not always go away. Every person and injury will have a different outcome, but there are some common signs to watch for immediately following the injury.
After the Injury
Immediately following a traumatic brain injury, the injured might experience varying degrees of confusion. He or she might feel dizzy, experience memory loss or lose consciousness altogether. Such symptoms are usually signs of severe injury.
In minor injuries, the injured commonly report dizziness, headaches, drowsiness or nausea.  However, in some cases, these symptoms might not appear right away, beginning days after the injury took place. The symptoms of a severe brain injury can look the same as a minor one at the start, so it is imperative that anyone with any type of head injury see a doctor. Do not wait for symptoms to subside. You might be causing further injury by delaying treatment.
