Module 4: Objectives
Knowledge
Describe common signs/symptoms of TIAs that are seen with ischemia in carotid territory
Describe two mechanisms that may explain transient monocular blindness.
List 4 of the major signs and symptoms seen after occlusion of the MCA stem in the language-dominant and in the non-dominant hemisphere, and relate each to damage in a specific neuroanatomic structure.
Clinical Applications and Reasoning
Explain how occlusion of the extracranial carotid artery can produce several different patterns of neurologic deficits (or in some cases, none at all).
Compare and contrast the patterns of clinical findings seen after occlusion of the superior MCA division in the language-dominant vs the non-dominant hemisphere.
Compare and contrast the patterns of clinical findings seen after occlusion of the inferior MCA division in the language-dominant vs the non-dominant hemisphere.
Clinical Applications to Patient Education
Develop points that you could use in explaining to a patient how he or she might personally experience a TIA produced by temporary occlusion of carotid branches.
