Q

Embolism

A

Part of a blood clot from somewhere else breaks off and travels to get caught in a thinner vessel.

Typically emerge from atherosclerosis but can come from the heart as well (after heart attack for example)

Study These Flashcards
A

Brain trauma
Tumors
Infections

25
Subcortical aphasia lesions sites
Basal ganglia + surrounding areas Thalamus Possible involvement of left cortical structures
26
Clinical profile of subcortical aphasia due to lesion in left basal ganglia + surroundings
- Fluent speech w/ possible hesitations - Good repetition - Normal auditory comprehension (possibly more difficult for complex material) - Motor speech problems (Broca's + prosody) - Preserved writing *Possible semantic paraphasias *Possible limb apraxia (Anomia, Broca, Wernicke, TMA)
27
Clinical profile of subcortical aphasia due to lesion to thalamus
Fluent aphasia with paraphasias and comprehension difficulties - Word finding + naming - Limited verbal output - Neologisms
28
Clinical profile of subcortical aphasia due to lesion to the cerebellum
- Decreased fluency - Mild anomia - Agrammatism - Mild speech comprehension difficulties
29
T/F: Individuals with expressive (Broca's) aphasia have better prognosis than receptive (Wernicke's)
True
30
Factors that can impact rehabilitation
- Age - Comborbidities + Etiology of problems - Site + size of lesion - Duration before beginning intervention - Motivation/behaviour - Type of aphasia* - Psychosocial support
31
When are the biggest gains made post-stroke?
Within the first 6-8 weeks
32
Window for intesive therapy w/ ++ gains
3-6 months
33
Total recuperation is very rare if gains not made within ___
One week
34
Which lobe is responsible for executive functioning and motor planning?
Frontal lobe
35
Which lobe is considered the sensory processing centre?
Parietal lobe
36
Sight and visual info processing centre
Occipital lobe
37
Auditory processing, memory and emotion centre
Temporal lobe
38
Balance, posture, equilibrium and movement control centre
Cerebellum
39
Vital body functions control centre
Brainstem
40
Part of the brainstem involved in regulating eye movement, arousal hearing and alertness
Midbrain
41
Main relay station btwn the brainstem and the cerebral cortex
Thalamus
42
Involved in chewing, facial movement, blinking and some balance
Pons
43
Involved in breathing, heartbeat, blood pressure and blood flow
Medulla (also the site of decussation for many cranial nerves)
44
Involved in regulating body temperature, heart rate, thirst and hunger
Hypothalamus
45
Lexical-syntactic breakdown
- Increased use of non-specific language - Omissions of various grammatical components - Ability to convey feelings/opinions greatly reduced
46
T/F: For most bilingual individuals, a stroke will affect both of their languages
True
47
T/F: Bilingualism is associated with better recovery for patients with aphasia
False - myth
48
What is pure alexia?
- Not able to recognize series of letters as familiar words, even if they recognize the individual letters - Main difficulty with the "voie d'adressage" but also assemblage
49
rTMS (non-invasive brain stimulation) has benefits for what kind of aphasia?
Can't be confidently recommended yet, but: Chronic/acute nonfluent (?)
50
What is agnosia?
Impaired understanding of the meaning of certain stimuli despite having no peripheral sensory impairment
51
You are assessing a woman with buccofacial apraxia. This alone suggests she might have what type of aphasia?
Broca's aphasia, transcortical motor aphasia, or conduction aphasia
52
A 48-year-old stroke patient was misreading words that were irregularly spelled (e.g., Wednesday) but had no problems with non-words that they had never encountered before (e.g., Diggle). This patient probably presents with:
Surface alexia (Difficulty with whole word recognition but voie d'assemblage is in tact)
53
A 68-year-old man experienced a stroke and had problems with reading; however, other language related skills like auditory comprehension, naming, writing, or oral repetition were not affected. This condition referred to as pure word blindness or alexia without agraphia is also called:
Pure alexia
54
Perisylvian region
Includes Broca's area and Wernicke's Around the lateral sulcus in the left hemisphere
55
Transference plasticity
Plasticity as a result of one training experience can improve the acquisition of comparable behaviours
56
Surface agraphia
- Phonemic errors, issues with homophones - Dictation of non-words relatively in tact - Less frequent words more likely to be impaired
57
Deep agraphia
- Sound-letter conversion problem - Often produces non-words that look visually similar to target word -
