Probable AICS |
|
|
Acute onset of neurologic dysfunction of any severity suggestive of focal brain ischemic syndrome but without imaging/laboratory confirmation of acute ischemic pathology (diagnostic studies were negative but insensitive for ischemic pathology of the given duration, severity and location). Imaging, laboratory, and clinical data studies do not suggest non-ischemic etiology: possible alternative etiologies are ruled out. |

Acute neurologic dysfunction of any duration or severity possibly consistent with focal brain ischemia without imaging/laboratory confirmation of acute ischemic pathology (diagnostic studies were not performed or were negative and sensitive for ischemic pathology of the given duration, severity and location). Possible alternative etiologies are not ruled out. Symptoms may be non-focal or difficult to localize. |
