ABI
Acquired Brain Injury: causes of brain injury (to CNS) follownig near-normal brain development (occured outside of neonatal period of life -> not birth or perinatal, 3 mo post natal cut off)
Types of ABI
1- non-traumatic : internal factors cause damage (ex: infeection, lack of oxygen) ex: encephalitis, meningitis, aneurysm, brain tumour, near-drowning, strokes
2- traumatic: external factors (ex: bumps, blow, jolt), can be open or closed head injury (ex: penetrating or accleration/deceleration impact)
ex: falls, MVA, pedestrial vehicle, gunshot
*accidental or not (inflicted)
TBI (Pediatric traumatic brain injury) incidence
-leading cause of death in those under the age of 19
- 1 in 30 newborns before they turn 6
- 500 in 100 000 will experience in a year
- 9.6% death canada
TBI predisposition factors
- incomplete fusion of skull
- disproportionaltely large head
- architecture of the pediatric brain
TBI major cuases per age group (0-1 16+, 1-5 60 +, 5-15, 15-60)
-violence
-falls
-bike/sporting
-motor vehicle collision
frontal lobe functions
voluntary movement, expressive langauge, higher level executive functions
perietal lobe
processing somatosensory information from the body (touch paain temperature limb position)
occipital lobe
visual processings, visuospacial, memory
temporal lobe
auditory info, encoding memory, emotion, language
injury frontal
- feeling like a different person (disinhibited or overly reserved)
- difficulty with initialtion
- decreased ability to focus and attend
- challenges with plannign and organizing simple activities
- decreased insight into imparments
injury parietal
-intergration of senses (touch, taste, temperature,e tc)
occipial lobe injury
-vision
-visual integration
temporal injury
- difficulty understanding words, follinwg directions, understanding/remembering stories
- trouble finding the right words to name objects, producing sentences, giving directions, giving explanations, retelling personal expriences
- reading
- understanding emotion of others
Cerebellum injury
-balance
- motor co-ordination
-body awareness
brainstem injury
-breathing
-consciousness
- heart rate
- blood pressure
-sleep
common clinical presentation abi (stroke, posterior fossa tumor, encephalitis), degrees of injury, what is present in nearly all abi cases,
stoke : word finding
posterior f t : temporary mutism
encephalitis: dysarthria
focal or diffuse
cognitif communication difficulties and sometimes disarthria (-> depends on the neural networks that are impacted)
predictors of long term outcomes of injury
- injury related ( severity, diffuse vs local)
- demographic (age at injury, home environmenet)
- pre-injury (pre=injuring fucntioning)
Cognitive communnication disorder (CCD)
difficulties with any aspect of sommunication (listening, speaking, gesturing, reading, writing, thinking) that is affected by disruption/impairment of cognition and cognitive processes, including attention, memory organization, problem solving, reasoning, executive functions
