DEFINTION of ABI:
Acquired brain injury is an injury to the brain that has occurred after birth
Damage to the brain resulting in a person’s lifetime, not due to birth.
Disruption of neurons and neuronal firing
Deterioration in cognitive, physical, emotional or independent functioning
What is ABI NOT considered (hereditary, congenital, degenerative)
“An injury to the brain, which is not hereditary, congenital, degenerative or induced by
birth trauma.
Hypoxia- is a condition in which the body or a region of the body is deprived of adequate
oxygen supply. Hypoxia may be classified as either generalized, affecting the whole
body, or local, affecting a region of the body
KNOW THE 6 LOBES (function + area)
case example- what part of the brain is responsible for that deficit
Frontal Lobe
CEO”, executive functioning, initiation, problem-solving, and goal directed activities
(thinking, planning, emotions, bx control, decision making)
Parietal Lobe
Sensory and motor stimuli input; recognition of touch, temperature, pain
(Perception, Object classification, spelling, numbers, visuospatial processing)
Occipital Lobe
Visual processing (vision, colour id)
Temporal Lobe
Processing auditory information, language, memory
(Facial recognition, hearing, vision, speech, emotion)
Cerebellum
Motor responses, coordination and muscle tone
(gross/fine motor skills, hand eye coordination, balance)
Brainstem
Basic life functions; respiration, heart rate, swallowing
(regulates body temp)

DIFFERENCE BETWEEN CLOSED HEAD INJURY VS PENETRATING HEAD
INJURY (what part of the brain gets breached)
example: concussion is a closed head, phineas gauge would be an example of a
penetrating head injury
PHINEAS GAGE
(Why is he important to this field of research: PERSONALITY CHANGE)
Had an accident with a tamping iron, went through frontal lobe/limbic system
Changed how we think about ABI.
Significant personality/ behavioural changes
Damage to the prefrontal cortex affects personality change and behavior change while
leaving other neurological functions intact
First case to make the link between acquired brain injury and personality changes
MEASURES OF SEVERITY OF INJURY: (3 different measure LOC, PTA, GSC)
How do you know?
Duration of loss of consciousness (LOC)
Less than 15 minutes: mild injury
Up to 6 hours: moderate injury
6-48 hours: severe injury
Over 48 hours: very severe
