not born with it
acquired
born with it
congenital
Not degenerative
aphasia
degenerative
dementia
generally have problems with language
aphasia
generally have problems with memory
dementia
talk, understand, and repeat well
anomic aphasia
only problem is anomia
anomic aphasia
echolalia
transcortical mixed aphasia
most severe type of aphasia
global
all transcorticals and anomic:
repeat better
blow from an external force
traumatic brain injury
skull not penetrated
closed head injury
skull penetrated
open head injury
non-traumatic brain injury
caused by strokes, encephalopathies, toxins, or tumors
brain does not get enough oxygenated blood
stroke
characteristics very similar to injuries by a blow from an external force
non-traumatic brain injury
likelihood of sustaining a TBI
males are 2x as likely as females
% of population with TBI
50% over age 18
50% under age 18
cause of TBI: < 5 yo
falls
cause of TBI: infants
shaken baby syndrome
cause of TBI: >65 yo
falls
vehicle accidents combined account for _______% of injuries
46
also plays a factor in TBI causes
drugs and alcohol
brain weight
2-3 lbs
brain consistency
jello/soft-boiled egg
focal injuries
primary impact - where the brain hits the skull; then skull is thrown front to back
axonal damage/diffuse axonal injury (DAI)
shearing/twisting
shearing/twisting results in:
DIFFUSE damage at the cellular level
most concerned with focal or diffuse?
diffuse
many times, MRI/CT scans will not show
the potential damage
shaken-baby syndrome: focal or diffuse?
diffuse
concussion
Minor (mild) TBI
no unconsciousness
Minor (mild) TBI
10% have life long problems
Minor (mild) TBI
motor
anterior
sensory
posterior
nausea, headaches, confusion, learning problems
Minor (mild) TBI
problems with employment and social interaction
Minor (mild) TBI
a period of unconsciousness (>30 minutes to 24 hours)
Moderate TBI
33% have life-long problems
Moderate TBI
more motor problems
Moderate TBI
more difficulty with cognitive communicative impairments
Moderate TBI
coma > 6 hours
severe TBI
severe motor problems
severe TBI
75% have life-long impairment
severe TBI
medical problems associated with TBI
seizures
orthopedic problems
bowl/bladder control - incontinence
sensory problems - hearing, vision, etc.
physical problems associated with TBI
can be mild (paresis = weakness) to serious (paralyzed/plegia)
watch from balance, strength, and coordination problems
perceptual-motor problems associated with TBI
visual neglect
motor apraxia-motor planning problems
cognitive-communication problems associated with TBI
dysarthria/apraxia of speech
tangential speech
confabulations
hyperverbosity
problems in writing, language, articulation, abstraction, reading comprehension
anomia
memory/attention/concentration problems
poor-problem solving
problems in executive functioning
egocentric thinking
tangential speech
taking multiple tangents
confabulations
says false statements, but does not know its false
hyperverbosity
too much talking
anomia
word finding problems (AKA dysnomia)
dysexecutive syndrome
problems in executive functioning
behavior problems associated with TBI
poor judgment/motivation
apathy, lethargy
emotional lability
impulsivity
disinhibition, anger outbursts
social problems associated with TBI
often the biggest concern
withdraw
easily distracted/influenced
bossy/argumentative
misperceive social actions and events
poor responsibility/dependency
loneliness/stubbornness
mood changes
perseveration
sexually inappropriate behavior
reluctance to see assistance
proactive intervention for TBI
look at what is ahead
determine obstacles/challenges they will confront
plan viable solutions for those problems
exercise creativity, ingenuity, and flexibility
involve key people
use many of the strategies used for LLD/DLD and ADHD
denial of injury
symptom of frontal lobe injury
strokes and aphasias
non-traumatic brain injuries
two types of strokes
ischemic
hemorrhagic
ischemic stroke
AKA occlusive
deficiency of blood
caused by blockage or constriction usually from within an artery
sticks to side of artery wall, does NOT move
thrombus
moves within arteries
embolus
hemorrhagic stroke
blood escaping into brain tissue
strokes can occur
anywhere in the brain or skull
