Final answer:
The statement is False. Multi-Infarct dementia is usually more rapid in onset than Alzheimer's dementia.
Step-by-step explanation:
The statement is False. Multi-Infarct dementia, also known as vascular dementia, is usually more rapid in onset than Alzheimer's dementia. Multi-Infarct dementia is caused by multiple small strokes in the brain, which can lead to sudden symptoms of dementia. On the other hand, Alzheimer's dementia is a progressive disease that develops slowly over time.
