0 No disease is present No disease is present
1 Definitely a potential cause of the index stroke: Deep branch artery stroke: small, deep infarct with diameter <15 mm on MRI (or CT) in the territory corresponding to symptoms and either (b) One or several old or silent lacunar infarcts in territories different from the index stroke or (c) Leukoaraiosis on MRI (or CT), microbleeds on MRI (gradient echo imaging), dilatation of the perivascular spaces on MRI (or CT) or (d) Recent repeated similar TIAs – when they preceded the brain infarct by 1 month or less and attributable to the same territory as the subsequent BI (which increase the prediction for lacunar stroke from 57 to 80%, and are therefore supportive).

2 Causality uncertain: (a) Single, deep branch artery stroke or (b) Clinical syndrome suggestive of deep branch artery stroke with no MRI/CT evidence of stroke (clinical syndrome suggestive of a deep branch artery stroke – classic lacunar syndromes: pure motor hemiparesis, pure sensory syndrome, ataxic hemiparesis, dysarthria clumsy-hand syndrome, and sensorimotor syndrome or other 'nonlacunar' clinical syndromes. e.g. hemichorea, hemiballism, isolated dysarthria, etc.).

3 Unlikely a direct cause of index stroke (but disease is present): Leukoaraiosis on MRI (or CT), and/or microbleeds on MRI (gradient echo imaging), and/or dilatation of perivascular spaces on MRI (or CT), and/or one or several lacunar infarcts (silent or old) in territories different from the index stroke.
