What is the difference between a mild and severe TBI?

The Brain Trauma Foundation states that every year, traumatic brain injuries affect approximately 2.5 million people, and you may be one of the many trying to cope with one of these injuries. These  life-threatening injuries  usually occur due to a violent jolt or blow to the body or head, or when an object penetrates the tissue within the brain.  

• Some of the symptoms and signs of a mild brain injury include the following:  
• Headache: Persistent or severe headache.
• Confusion: Feeling disoriented or confused.
• Dizziness: Experiencing dizziness or loss of balance.
• Nausea or Vomiting: Feeling nauseous or vomiting shortly after the injury.
• Blurred Vision: Changes in vision, such as blurred or double vision.
• Ringing in the Ears: Hearing ringing or other noises in the ears (tinnitus).
• Fatigue: Feeling unusually tired or lethargic.
• Sleep Disturbances: Trouble falling asleep, staying asleep, or sleeping more than usual.
• Memory Problems: Difficulty remembering new information or recalling events before or after the injury.

If you sustain a  severe brain injury , you may experience any of the symptoms of a mild TBI in addition to others that occur within the first few hours to the first few days after the accident. For example, you may develop a constant headache that worsens over time, have a hard time waking up from sleep, experience seizures or convulsions or have clear fluids drain from your ears or nose.
