Q

Why was there a sudden burst in neurogenic communication disorders?

A

WW2 many soldiers survived TBI’s so there was a burst in these disorders and a need to provide rehabilitation

Q

What are some secondary results of CVA?

A

Edema or swelling in the brain, infarct or tissue death in the area of the stroke, or spontaneous recovery which is when the brain reorganizes and takes over the function that was lost in different areas

25
What lobe is wernickes in?
Temporal
26
What is the hearing/auditory comprehension pathway?
Ears - auditory pathway - CN 8 - temporal lobe - Heschl's gyrus - wernickes area
27
What is the speaking pathway?
Wernickes - arculate fasiculus - broca's area - primary motor cortex - brainstem - cranial nerves
28
Why do we test repetition for aphasia?
Can the word get in & can the word get out (listening & producing)
29
Brocas Aphasia
Fluency = impaired, auditory comprehension = good, repetition = impaired, naming = impaired
30
Wernickes Aphasia
Fluency = good, auditory comprehension = impaired, repetition = impaired, naming = impaired
31
Global Aphasia
Fluency, auditory comprehension, repetition, naming = impaired
32
What is fluency?
Effortless speech, normal rate, grammar okay, syntax okay, intonation okay, uses all types of words
33
What is non-fluency?
Effortful speech, slow rate (under 100 wpm), grammar reduced, syntax poor, monotone, leave out function words and rely on nouns
34
Broca's aphasia example
agrammatic speech (lots of nouns), loss of function words, nouns and verbs, misarticulating (dysarthria), frustration and awareness
35
Wernicke's aphasia example
verbal paraphasias (fork for spoon), right category but wrong word, neologisms (new words/jargon), get overall just of convo but could not understand specifics, could not follow instructions or comprehend reading
36
Global aphasia example
stereotypical utterances, over learned phrases, single words, speech limited, can hardly respond to yes/no questions
37
Does a person with slow laborious speech, grammatical, and phonemic errors have slow and laborious writing with grammatical errors as well?
Yes
38
Motor speech disorders
Disorders of speech resulting from neurologic impairment affecting the motor programming and/or neuromuscular execution of speech (apraxia and dysarthria)
39
Apraxia
Disorder of motor programming for speech (planning, not caused by paralysis, weakness, incoordination, or sensory. loss, damage to CNS, oral groping, inconsident, write fine
40
Dysarthria
A group of speech disorders resulting from disturbances in muscle control of speech mechanism (neuromuscular execution), damage to CNS/PNS, speech problems result from paralysis, weakness, incoordination, sensory loss (drunk slurred speech), execution problem
41
Problem with cognitive linguistic process (throughs translated to language)
Aphasia, right hemisphere disorder, cognitive communicative disorders in TBI
42
Problem with motor speech planning/programming (language translated into motor movements)
Apraxia of speech
43
Neuromuscular execution of motor speech (motor movement carried out by CNS and PNS)
Dysarthria
44
Damage to wernickes
Aphasia
45
Damaga to Brocas
Aphasia and/or Apraxia
46
Damage to arcuate fasciculus
Aphasia
47
Damage to motor strip
Dysarthria
48
Damage to cranial nerves
Dysarthria
49
Dementia
Cognitive Communication disorder
50
Alzheimers
Memory
51
Frontal lobe
Decision making, personality
52
Primary progressive aphasia
Language
53
Cognition
Language, memory, attention, decision making
54
TBI risk factors (more likely to get it if..)
Alcohol and drugs, poor school adjustment, socioeconomic status, personality type, pervious history of TBI, participation in sports
55
First injury
2 seconds direct effect of the injury where the brain is accelerated, decelerated, or rotated
56
Can first injuries occur twice?
Yes, hit head on windshield and then flung out of the car
57
Second injury
Occurs in first few hours post onset, it is the physiological response to injury (could include oxygen deprivation to brain, blood loss, hematomas, increased inter cranial pressure, decreased blood pressure, swelling
58
Open head injury
The skull is open/cracked, brain is exposed (gunshot)
59
Closed head injury
Skull is closed/intact (falls)
60
Mild brain injury
Brief or no loss of consciousness, the CT and MRI is negative (looks normal), symptoms could be vomiting, dizziness, lack of recall
61
Moderate brain injury
Coma less than 24 hours, could see things on a CT or MRI, could be hemorrhage (bleeding) or skull fractures (tissue damage)
62
Severe brain injury
Comas is greater than 24 hours
63
Cognitive deficits following TBI
focusing problems, delayed response time, organization, difficulty multitasking, poor judgement, bad spacial functions, etc
64
Language Cognitive deficits following TBI
Word finding is hard, prosody is flat, topic selection, maintenance, turn-taking, and consciousness are off
