The mechanism of brain trauma occurs when inertia causes the brain to hit the skull from the blunt impact. The brain damage will depend on the force of the impact and whether or not the skull has suffered a fracture.
Types of Cranioencephalic Trauma Head injuries are divided into three degrees according to their seriousness: mild or concussion, moderate, and severe. To find out what type of injury a person with a head injury has, a scale of neurological response is used. It is called the Glasgow Scale as it was described by two neurosurgeons at the University of Glasgow in 1974. The scale measures the neurological response in its visual, oral, and motor parts. It is a very important tool that everyone should know since through it, the degree and evolution of a cranioencephalic trauma is diagnosed in addition to giving you an objective view of the severity.
GLASGOW COMA SCALE: 1 EYE VERBAL MOTOR
2 Opens eyes in response to pain Makes sounds
3 4 5 Does not Opens eyes Opens eyes N/A open eyes in response spontaneously to voice Makes no Words Confused, Oriented, sounds disoriented converses normally Makes no Extension to Abnormal Flexion / Localizes movements painful flexion to withdrawal to to painful stimuli painful painful stimuli (decerebrate stimuli stimuli response) (decorticate response)
6 N/A N/A Obeys commands
a) Scoring Eye Response (E) 1. No opening of the eyes: severe damage 2. Eyes opening in response to pain stimulus. A pain stimulus, such as squeezing the fingernail, is enough to see if there is a response. The stimuli could be on any limb. 3. Eyes opening to speech. Not to be confused with the awakening of a sleeping person, such people receive a score of 4, not 3. 4. Eyes opening spontaneously Maximum score: 4 points Verbal Response (V) 1. No verbal response: severe damage 71
