After Midterm Flashcards
CVA typically affect what type of people
older
Risk increases with age and slightly more common in
men
of the people we will see with stroke there is a small percentage that
doesn’t have any impairment at all.
Per 100 stroke survivors - break it down
10 have no more impairments
40 have mild residual deficits
40 have long term deficits
10 need institutional care
A very small percentage of stroke have long term
nursing home care
what is ischemic stroke
Most common. There is a blockage in the vessels. with age and time the blockage can develop. plague build up in the vessel walls. over time it will narrow it makes it harder for the blood to push through.
what is hemorrhagic stroke
less common. vessels get weaker and tear and bleed. typically the person will have surgery to repair the rupture.
what is transient ischemic attach (TIA)
an event that results in neurological symptoms resembling a stroke.2 Although these symptoms develop suddenly and may last up to 24 hours, they resolve completely, leaving no discernable symptoms or deficits.2 TIAs are considered a “warning sign” of an impending stroke and precede approximately 12% of all strokes.
What is a thrombotic stroke
Type of ischemic stroke that is a stationary clot
What is a embolic stroke
a type of ischemic stroke, traveling clot formed elsewhere in the body.
What is a lucunar infarct
Small holes in deep cerebral hemipsphere, pons or basal ganglia
smaller vessel blockage
pure motor ataxic or sensory loss
good prognosis - mild stroke, mild symptoms
Anterior cerebral artery infarct (ACA)
Frontal and parietal lobes
majority of corpus callosum
motor and sensory cortices of leg and foot
motor planning areas.
more difficulty walking and better clinical picture with their arm.
ACA impairment symptoms
contralateral hemiparesis - opposite side of body than brain.
behavioral changes - impulsive.
apraxia - ideomotor or ideational
aphasia - expressive or receptive
Middle cerebral artery infarct afects what type of brains
lateral areas of hemispheres
primary motor and sensory cortices face, trunk, arm, hand
Middle Cerebral Artery (MCA) impairments
left hemisphere damage - apraxia, aphasia
either hemisphere damage
contralateral hemiplegia and sensory loss
homonymous hemianopsia - loss of vision in both of the eyes.
Right hemisphere damage
neglect
visuospatial impairmemnt
emotional lability
behavior disturbance
strong gaze preference toward lesion side.
what is homonymous hemiplegia
loss of vision of part of both eyes. like half of each eye. they need a behavioral optomitrist. What we call a field cut.
if patient has a r brain infarct which side will they look to more
left side.
what is emotional labile
inappropriate expression of emotion - like crying or laughing.
Broca aphasia
trouble with expression, slow effortful speech, short phases less than 4 words. poor repetition ability, comprehension intact.
speech might be really slow and effortful.
Wernicke aphasia
receptive aphasia. A combination of real words and made up words.
paraphasias - saying words a little off that it actually should be.
neologisms - non words, made up words
poor comprehension and repetition
speech apraxia.
what is dysarthria
a motor articulation problem. speech is unclear or garbled. they can’t get the mouth to make the sounds.
what is neologisms
made up words
with a patient with aphasia is it important to do your treatment how
in context.
posterior cerebral artery infarct - where in the brain?
temporal and occipital lobes
primary visual areas, memory, visual spatial analysis, writing, & reading
what does the posterior cerebral artery impairment affect
Left - anomia, agraphia, acalculia, alexia, dyslexia
Right - cortical blindness
L/R discrimination errors
visuospatial impairments
Either hemisphere damage - contralateral hemiplegia and sensory loss
visual field cut
visual agnosia
memory loss
(look up these words, make seperate cards)
vertebral basilar artery infarct affects what part of brain
pons, midbrain, thalamus, caudate nucleaus, lateral medulla, cerebellum
deficits from vertebral basilar artery deficits
Loss of consciousness
brainstem or cranial nerve damage
hemi or quadriplegia
memory loss
agitation
comatose or vegetative state
locked in syndrome
Patient scenario
Toni has is HIV+ along with stroke. multiple strokes, presents with more weakness in L than R. she’s has bilateral CVA’s (less common). She was depressed in rehab. uses a power wheelchair. LIves alone in accesable apartment. hospital bed, roll in shower. Wears bilateral AFO
What are some challenges with her as she ages impact on occupation?
What might be important home and community encironment adaptations
what activity adaptations that might be appropriate
modifying transfers, adaptations for loss of vision. strength, weakness, cognition, memory. She says she independent.
home and community adaptation - jar openers, easier to grip pots and pans.
activity adaptation - if there is a congntive deficity, timed medication dispenser.
Acalculia / dyscalculia
the inability or impaired ability to perform simple mathematical calculations previously mastered
Agnosia
the inability to recognize objects, persons, smells or sounds despite having normal sensory functions
agraphia / dysgraphia
the inability or impaired ability to produce written language
Alexia / Dyslexia
the inability or impaired ability to read written language despite preservation of other aspects of language
Aneurysm
a weakening of an artery wall resulting in a bulge or distension of the artery
Anomia
the inability to name objects or persons
Anosognosia
An unawareness or denial of a neurological deficit that is clinically evident
Aphasia
an acquired multimodality language disorder that results from damage to the language center of the brain
apraxia
The inability to perform purposeful actions despite having normal muscle function
arteriovenous malformation
A tangle of abnormal blood vessels connecting arteries and veins without an intervening capillary bed
Contracture
An abnormal shortening of muscle tissue rendering the muscle highly resistant to passive stretching. Typically results in permanent restrictions in joint motion
Contralateral homonymous hemianopia
An ocular condition where vision has been lost in the same field halves of both eyes
Dysarthria
A speech disorder resulting from paralysis, weakness or incoordination of the muscles involved in speech production
Dysphagia
An eating disorder involving difficulty in manipulating and transporting liquids / solids from oral cavity to pharynx.
hemianesthesia
A loss of sensation in either half of the body
spasticity
A velocity - dependent increase in tonic stretch reflexes. Also denotes a form of muscular hypertonicity with exaggeration of tendon reflexes.
Subluxation
an incomplete or partial dislocation of a joint
Occlusion of the internal carotid artery commonly results in
contralateral hemiplegia, hemianesthesia, homonymous hemianopia, changes in mental functions, and behavioral disturbances
If the stroke occurs in the dominant hemisphere (i.e., hemisphere containing the representation of speech and controlling the extremities used to perform skilled movements such as writing and kicking a ball; the left hemisphere in the majority of individuals), the patient may also present with
aphasia, agraphia or dysgraphia, acalculia or dyscalculia, and apraxia.
If the nondominant hemisphere is involved, the patient may present with
visual perceptual impairments, unilateral body or spatial neglect, anosognosia, and dressing apraxia.
An occlusion of the anterior cerebral artery typically produces
contralateral hemiparesis and somatosensory loss, impacting the leg to a greater degree than the arm.5 Behavioral disturbances, apraxia, and mental changes—such as confusion, disorientation, decreased initiation, and impairments in attention and short-term memory—are often present.

Wht are some things that you want to evaluate?
vision, balance - if it’s safe to do so, sensation, upper quarter screen - functional range of motion no goniometry. Barthel assessment, transfers and self care skills. Cognition - does he know where he is and does he know what happened to him. mini mental or inpatient rehab. Maybe texas if he has the attention for it.
When doing an assessment of a person with CVA what are some things to consider?
- location and type of brain infarct
- factor co-morbidities including any prior CVA
- consider treatment setting
- client goals and preferences
- social/premorbid status-living alone? driving?
