Operational definitions of ARWMC scale.


Score	Frontal lobe, parietal-occipital lobe, temporal lobe, and infratentorial region	Basal ganglia

0	No lesions (PVWMC: symmetrical, well-defined ventricle, or DWMC < 5 mm)	No lesions
1	Focal lesions (PVWMC, nonsymmetrical caps or bands < 5 mm, or DWMC between 5 and 9 mm)	One focal lesion (5 mm)
2	Beginning confluence of lesions (PVWMC between 5 and 10 mm or DWMC between 10 and 25 mm or connecting bridge between two focal lesions)	More than one focal lesion
3	Diffuse involvement of most region (PVWMC > 10 mm or DWMC > 25 mm)	Confluence of lesions

ARWMC, age related white matter changes; PVWMC, periventricular white matter changes; DWMC, deep white matter changes. This table is from [16].
