A proposed classification of subcortical infarcts is presented. The cl
assification is a clinicoradiological one with the distribution of inf
arcts based on known vascular territories and the borderzones between
them. The document is in two sections: section A gives the broad frame
work of the classification, while section B gives more detail concerni
ng terminology, location of infarcts, presumed pathogenesis, common cl
inical expressions of infarct types and radiological appearances. It i
s hoped that this document will act as means of establishing a common
language concerning this important group of infarcts, thereby facilita
ting management and providing a framework for further research.
