Patterns of Ischemia

Because cell injury can be reversible depending on the amount of time spent without adequate blood flow and oxygen, three distinct patterns of stroke have been defined. The first pattern is the transient ischemic attack (TIA), which is a transient focal neurological deficit lasting less than 24 hr but usually resolving between 10 min and 4 hr. A common type of TIA, known as amaurosis fugax, causes transient monocular blindness, which is often described as ''a shade being pulled'' over one eye. The second pattern is the reversible ischemic neurologic defect (RIND). A RIND is defined as a focal neurologic deficit lasting more than 24 hr but completely resolving within 1 week. The final pattern of ischemia is the cerebrovas-cular accident (CVA). A CVA is a permanent focal neurologic deficit that may improve over time to a limited extent.
