Proposed Sub-classification of white matter lesions

	Juxta ventricular	Peri ventricular	Deep	Juxtacortical
Locations	Within 3mm from ventricular surface	Periventricular watershed zone 3–13mm from ventricular surface	Between periventricular white matter and juxtacortical white matter	Within 4mm from corticomedullary junction
Etiologies	CSF leakage	Hypoperfusion	Small vessel disease	Small vessel disease
Pathologies	Non-ischemic	Ischemic	Ischemic	Ischemic
Functions	-	Disruption of long WM tracts	Disruption of long WM tracts	Disruption of U fibers
