In brief: Symptoms

The difference between a mild brain injury and a serious one is the degree of impairment.
Mild brain injuries damage small portions of the brain (or ones less import for basic life support) whereas serious brain injuries damage extensive portions of the brain (or areas critical to life support).

In brief: Exams/mental status

People with a mild brain injury usually return to a normal mental status very quickly.
If a ct scan was performed and was abnormal, this is a sign of a more serious injury. And if certain symptoms like headache, dizziness, blurry vision, memory and concentration difficulties persist, this also indicates a more serious injury. Any of these should be checked out by your doctor.
