Artery Stroke Defici
Deficits that commonly occur following strokes in specific arteries
Question | Answer |
---|---|
Anterior Cerebral artery: somatosensory | Loss of sensation in lower limb |
ACA: Motor | Apraxia; hemiplegia(lower limb more affected than upper limb and face); impaired gait |
ACA: special senses and autonomic function | No changes |
ACA: emotions and behavior | flat affect; impulsiveness; perseveration; confusion; motor inactivity |
ACA: cognition, language, memory | difficulty with divergent thinking |
ACA:other | urinary incontinence |
Middle Cerebral Artery: somatosensory | hemianesthesia affecting face and upper limb more than lower limb |
MCA: motor | face and upper limb more impaired than lower limb; if striate arteries involved, lower limb paresis or paralysis in addition to face and upper limb impairment |
MCA: special senses and autonomic function | homonymous hemianopia |
MCA: emotions and behavior | If right hemisphere-->left hemiplegia, easily distracted, poor judgment, impulsiveness; If left hemisphere-->right hemiplegia, apraxia, compulsiveness, overly cautious |
MCA: cognition, language, memory | Left MCA-->aphasia Right MCA--> difficulty understanding spatial relationships; neglect; impairment of nonverbal comunication, dressing apraxia, constructional apraxia |
MCA: other | None |
Posterior cerebral artery: somatosensory | hemianesthesia; slow pain is preserved |
PCA: motor | hemiparesis; If lesion near origin of artery-->vertical gaze palsy;oculomotor nerve palsy, loss of medial deviation of the eyes with preserved convergence, vertical skew deviation of the eyes |
PCA: special senses and autonomic function | homonymous hemianopia; cortical blindness; hallucination; lack of depth perception; impaired eye movement, except lateral and inferomedial eye movements; visual agnosia; limbs may show vasomotor and/or trophic abnormalities |
PCA: emotions and behavior | memory loss |
PCA: cognition, language, and memory | difficulty reading |
PCA: other | None |
Basilar artery: somatosensory | bilateral sensory loss |
BA: motor | tetraplegia; abducens nerve palsy(palsy of lateral gaze); locked-in syndrome; oculomotor nerve palsy; decorticate or decerebrate rigidity; paresis or paralysis of muscles of the tongue lips palate, pharynx, and larynx |
BA: special senses and autonomic function | vertigo, diplopia, vomiting, nausea, nystagmus, hearing loss, pupil constriction(involvement of descending sympathetic fibers in the pons; however, pupils may be reactive to light) |
BA: emotions and behavior | None |
BA: cognition, language, and memory | reduced consciousness |
BA: other | Coma |
