What are the neurobehavioral symptoms associated with Traumatic Brain Injury?
The Traumatic Brain Injury severity spectrum ranges from mild impact with no behavioral syndromes, resulting in no lasting structural injury and producing only transient and temporary changes in neurologic function, to patients in prolonged coma/vegetative state from catastrophic brain injury.
Cognitive impairments after a concussion can include difficulty concentrating, difficulty remembering, feeling in a “fog,” feeling slowed down, forgetting recent events, confusion, repeating questions, answering slowly, and amnesia.
The duration of posttraumatic amnesia (PTA) can also provide an indication of injury severity ranging from very mild (<5 minutes) to extremely severe (>4 weeks). Retrograde amnesia involving minutes, or more rarely days, immediately preceding the accident frequently accompanies PTA.
