Kidwell and Warach listed diagnostic criteria for the acute ischemic cerebrovascular syndrome (AICS). The authors are from the University of California at Los Angeles Stroke Center and the National Institute of Neurological Disorders and Stroke.
Parameters:
(1) acute onset of neurologic dysfunction
(2) imaging and laboratory findings
(3) alternative diagnoses
Acute Onset of Neurological Findings
Imaging and Laboratory Findings
Alternative Diagnoses
AICS Diagnosis
consistent with focal brain ischemia
confirm acute vascular ischemic pathology
NA
definite
suggestive of focal brain ischemia
negative but insensitive
ruled out
probable
possibly consistent with focal brain ischemia; nonfocal or difficult to localize
negative but sensitive, or not done
not ruled out
possible
acute onset of neurological findings
confirm non-ischemic pathology
NA
not AICS
where:
• Diagnostic studies may or may not be sensitive for ischemic pathology of the given duration, severity and/or location.
