Severe Brain Injury
Physicians and neuropsychologists classify brain injuires into specific categories. The most serious classification is the severe brain injury. The causes leading to a severe brain injury include a violent hit on the head, a fall, violent assault on the head, car or bike accidents and accidents during any sporting or recreational activity.
The intensity of the impact can pierce the skull injuring the underlying brain tissues. Severe brain injury can also happen when the car in which the victim is traveling either accelerates or decelerates suddenly, causing the brain to crash against the inside wall of the skull. Mass lesions like hematoma (blood clot in or on the surface of the brain) and contusions (laceration of brain tissues) are the usual internal damages of such traumatic events. These damage the message-transmitting neurons of the brain, impairs its normal functioning, leaving the victim disabled.
The typical symptom of a closed brain injury like that sustained in a severe brain injury is characterized by loss of consciousness and subsequent coma. The length of time during which the victim remains unconscious is a deciding factor of the severity of the trauma. Symptoms include:
- Pain in the head
- Feelings of giddiness, nausea and vomiting
- Lethargy
- Mentally perplexed
- Dilatation of pupils
- Vision impairment
- Leakage of cerebrospinal fluid through orifices like ears or nose
- Impairment of cognitive faculties
- Breathing problems
- Impairment of speech and verbal expression
- Swallowing problems
- Alteration of mental and behavioral traits
Extent and speed of recovery would entirely depend on the severity of the condition. The degree of recovery as well as the time during which the patient remain unconscious in the first month after the trauma is indicative of complete recovery in the long run.
