Symptoms and Decline
As vascular dementia progresses, symptoms increase and overall functioning further declines.

This is often referred to as a “step-like progression” or “stepwise” pattern of progression.
In other cases, there’s a less clear trigger for the decline.
Progression is also affected by other brain changes.
For example, some people with vascular dementia also have some evidence of Alzheimer’s disease in their brains.
This is called mixed dementia, and it’s often not discovered until an autopsy after death.
