CVA Clinical Syndromes Flashcards
(16 cards)
Anterior Cerebral Artery (ACA) Infarct
–Contralateral hemi-motor deficits LE > UE
–Contralateral hemi-sensory loss LE > UE
–Apraxia (dominant > non-dominant)
–Bilateral integration deficits
–Transcortical Aphasia (dominant > non-dominant)
–Urinary incontinence
–Visual deficits (visual fields)
–Significant cognitive deficits
Middle Cerebral Artery (MCA) Infarct
–Contralateral hemi-motor loss UE > LE
–Contralateral hemisensory loss UE > LE
–Dysarthria
–Apraxia (dominant > non-dominant)
–Aphasia (broca’s, wernicke’s, global)
–Perceptual Deficits (non-dominant > -dominant)
–Behavioral impairments
Dominant: cautious
Nondominant: impulsive
–Visual deficits (visual fields, smooth pursuits, saccades)
–Contralateral dysconjugate gaze
MCA Lacunar Infarct
Internal capsule damage (3 scenarios):
1) “Pure motor hemiparesis”
2) Motor + sensory deficits
3) Cognitive and behavioral deficits
Basal ganglia damage:
Significant motor control & motor planning deficits
Internal Carotid Artery (ICA) Infarct
–ACA + MCA lost
–UE & LE deficits
–Impairments tend to be significant
Posterior Cerebral Artery (PCA) Infarct
Peripheral territory
–Contralateral homonymous hemianopsia
–Cortical blindness (bilateral infarcts)
–Visual agnosia (dominant > non-dominant)
–Prosopagnosia
–Memory impairment
–Topographical disorientation (non-dominant > dominant)
–Dyslexia
Posterior Cerebral Artery (PCA) Infarct
Deep territory
–Thalamic pain
–Spontaneous pain & dysesthesias
–Involuntary movements
–Contralateral hemiplegia
ACA-MCA Watershed Infarct
–Proximal limb involvement
–“Man in the barrel” syndrome
–Dominant hemisphere: transcortical aphasia
MCA-PCA Watershed Infarct
–Disturbances in higher-order visual processing
–Cortical blindness possible
Common characteristics of RIGHT hemispheric damage
–Perceptual deficits are more common
–Quick, impulsive behavior
–Fair insight, poor judgment, unrealistic
–Inability to self-correct
–Difficulty perceiving emotions
–Difficulty problem solving
–Rigidity of thought
Common characteristics of LEFT hemispheric damage
–Language deficits are more common
–Cautious, slow
–Disorganized
–Hyper-aware of deficits
–Difficulty expressing emotions, flat affect
–Disorganized thought process
–Difficulty initiating tasks
–Perseveration
Superior Cerebellar Artery (SCA) Infarct
–Ipsilateral Ataxia - truncal and appendicular
–Ipsilateral oculomotor impairment - smooth pursuit and saccades
Medial pontine syndrome
paramedian branches of basilar artery
–Ipsilateral paralysis of conjugate gaze (will cause diplopia)
–Contralateral ataxia
–Contralateral facial & body weakness
–Contralateral sensory facial & body sensory loss (dorsal column)
Lateral pontine syndrome
AICA
–Nystagmus (causes vertigo, nausea, vomiting)
–Ipsilateral facial weakness
–Ipsilateral facial sensory loss (temp and pain)
–Ipsilateral hearing loss, tinnitus
–Ipsilateral ataxia
–Contralateral body sensory loss (anterolateral system)
Lateral medullary syndrome (Wallenberg’s Syndrome)
PICA or vertebral artery
–Ipsilateral facial pain/temp loss
–Contralateral body sensory loss (anterolateral systems)
–Ipsilateral ataxia
–Nystagmus (causes vertigo, nausea, vomiting)
–Dysphagia, dysphonia, impaired gag reflex
–Due to palatal and laryngeal paralysis
Ipsilateral Horner’s Syndrome
>Miosis
>Ptosis
>Anhidrosis
Medial medullary syndrome
vertebral artery
–Ipsilateral tongue weakness
–Contralateral body weakness
–Contralateral body sensory loss (dorsal column)
Vertebrobasilar artery syndrome (Locked-In Syndrome)
–Complete tetraplegia
–Bilateral cranial nerve palsy
Upward gaze spared
Blink spared
COGNITION SPARED
