Table 3 The Edinburgh Criteria for predicting the probability of Chronic Amyloid Angiopathy (CAA) as the underlying cause of ICH

From: Computed tomography in acute intracerebral hemorrhage: neuroimaging predictors of hematoma expansion and outcome

Edinburgh criteria

High probability of CAA

Lobar ICH with subarachnoid hemorrhage on CT

 

AND

 

  Finger-like projections from the ICH on CT

 

OR

 

  Possession of at least one APOE ε4 allele

Intermediate probability of CAA

Lobar ICH with either

 

  Subarachnoid hemorrhage on CT

 

OR

 

  Possession of at least one APOE ε4 allele

Low probability of CAA

Lobar ICH with neither subarachnoid hemorrhage nor possession of any APOE ε4 allele

  1. CAA Cerebral Amyloid Angiopathy, ICH Intracerebral Hemorrhage, APOE Apolipoprotein E
