Vascular dementia presents with cognitive decline that follows which event?

Vascular dementia is caused by cerebrovascular disease, so the cognitive decline is tied to a cerebrovascular event—most classically a stroke (or multiple small strokes) that produces infarcts and chronic hypoperfusion. After such an event, you often see a stepwise or fluctuating deterioration in cognitive function as new vascular injuries occur, reflecting the vascular basis of the disease. This pattern helps distinguish it from other dementias: Alzheimer's typically shows gradual, continuous decline without a clear preceding stroke. Seizures can cause acute confusion, but not the gradual, event-linked dementia pattern; brain infection or metabolic disturbance can cause delirium or acute cognitive disruption rather than a progressive decline tied to cerebrovascular injury.
