Artery Stroke Defici

Deficits that commonly occur following strokes in specific arteries

QuestionAnswer
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
