Which of the following characterizes Vascular Dementia compared to Alzheimer's Disease?

Vascular dementia is characterized by a more acute onset compared to Alzheimer's disease. While Alzheimer's typically has a gradual progression where symptoms develop slowly over time, vascular dementia can arise suddenly, often following a stroke or series of small strokes that impact blood flow to the brain. This sudden change in cognitive function distinguishes it from the insidious onset seen in Alzheimer's.

The differences arising from the underlying pathophysiology also manifest in other symptoms. For instance, in vascular dementia, focal neurological symptoms can often be present due to the specific areas of the brain affected by vascular damage. While personality changes can occur in both dementias, they may vary in presentation and severity between the two conditions. Therefore, the acute nature of the onset is a key feature in identifying vascular dementia in contrast to Alzheimer's disease.
