Which option correctly pairs onset patterns with vascular dementia subtypes?

Onset patterns in vascular cognitive impairment help explain how the disease presents and which vascular processes are likely involved. A single strategic infarct is a stroke in a critical brain region that can cause a sudden, focal decline in cognition, producing a vascular-dementia–like picture after one event. The classic vascular dementia that reflects accumulating vascular injury from multiple strokes is multi-infarct dementia, which typically shows a stepwise deterioration as new infarcts occur. Underlying many forms of vascular cognitive impairment is small vessel disease affecting white matter, the pathology behind leukoaraiosis and related subcortical vascular conditions such as Binswanger’s disease. The combination of a single strategic infarct as the onset pattern, with multi-infarct dementia as the vascular-dementia subtype, and small vessel disease affecting white matter as the underlying mechanism, best aligns these concepts.
