Getting injured entails frustration on the part of the harmed person. Not only can an injury inhibit a person's bodily function, the activities he can do is also very limited. Injured people at one point can't even make a living because the damage has impaired their ability to work.

The aggravation may be even greater if the injury is in the head. Head injury is a general term used to refer to a trauma to the head and the brain. Some of the reported causes for head and brain injuries are lack of oxygen, aneurysm or other diseases, electric or lightning shock, or a trauma to the head due to accident or assault.

In the event of a head or brain injury, a permanent brain damage may occur. However, there are no medically-accepted criteria yet that can predict permanent brain damage from trauma. Doctors consider the following factors, but normal findings on the tests below don't necessarily mean that there is no injury.

  • Concussion: Concussion is the "alteration of conscious awareness." Post-concussion syndrome, or symptoms following a concussion, includes dizziness, vomiting, headache, disorientation, forgetfulness, irritability, depression, mood swings, insomnia, and loss of libido.
  • Encephalopathy: A disturbance that results to temporary improper functioning of the brain indicates that something is wrong with both sides' gray matter. Signs include confusion, memory loss, inattention, agitation, and aggression.
  • Focal Neurologic Signs: Signs that determine that a part of the brain is not functioning.
  • Loss of Consciousness (LOC): Loss of conscious awareness range from a brief daze to several days of coma. Focal head trauma can permanently damage the cerebral hemisphere without LOC. In blunt head trauma, LOC usually results to permanent brain damage. Generally, the period of unconsciousness influences the injury's severity. A "Glasgow Coma Scale" is used to determine the patient's neurologic status (three for deeply comatose, 15 for normal value).
  • PERL: This test determines if the "Pupils are Equal and Reactive to Light." Unequal or unreacting pupils can signify an increase in intracranial pressure.
  • Post-traumatic Amnesia: PTA refers to memory loss of events that happened before (retrograde amnesia) and after (anterograde amnesia) the injury. Longer periods of PTA may imply a more severe injury.
  • Seizure: A seizure occurs when brain nerve cells fires electrical discharges at one another. This causes loss of consciousness and convulsion.
