While sometimes it is clear that someone has suffered a traumatic brain injury, some signs and symptoms may not be apparent right away. If you believe you have experienced a brain injury, seek immediate medical attention if you develop any of the following:
Unexplained or chronic headache
Unexplained nausea
Dizziness
Vomiting
Fatigue
Tingling or loss of feeling in limbs or extremities
Confusion or memory loss
Loss of consciousness
Brain injuries require immediate medical assistance. When left untreated, they are more likely to result in long-term issues.
