DMV White Matter Injury Severity Scoring System

	Points	Scoring
Cerebral edema	0-3	None = 0, right or left = 1, bilateral asymmetric = 2, bilateral symmetric = 3
Corpus callosum	0-3	1 point each for genu, body, and/or splenium lesions
RIGHT cerebral WM		Score each cerebral hemisphere region for punctate, linear and/or cavitary lesions
Frontal	0-12	Punctate: mild (1-3 lesions)=1, moderate (4-6 lesions)=2, severe (>6 lesions)=3
Parietal	0-12	Linear: mild (1-3 lesions)=1, moderate (4-6 lesions)=2, severe (>6 lesions)=3
Occipital	0-12	Cavitary: mild (1-3 lesions, <15mm)=2, moderate (4-6 lesions, <15mm)=4
Temporal	0-12	severe (>6 lesions, <15mm OR 1+ lesion >15mm)=6
LEFT cerebral WM
Frontal	0-12
