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.
