Traumatic Brain Injury A to Z - Symptoms of Moderate to Severe TBI


Symptoms of Moderate to Severe TBI

The symptoms of moderate to severe TBI are very serious and can have an effect on many aspects of the patient’s life. With moderate to severe injuries, a coma is not uncommon. As the patient comes out of the coma, they may have some of the following symptoms:
  • a headache that gets worse or does not go away
  • dizziness
  • pain
  • fatigue
  • repeated vomiting or nausea
  • convulsions or seizures
  • the inability to wake up from sleep
  • dilation of one or both pupils of the eyes
  • problems speaking
  • weakness or numbness in the hands and feet
  • loss of coordination
  • confusion, restlessness, or agitation, and
  • problems sleeping

Another symptom of TBI is memory loss, called post-traumatic amnesia, or PTA. How long the amnesia lasts helps determine how badly the brain is injured. If PTA lasts for more than one week, long-term problems with thinking, planning, behavior and personality are more likely.
