In brief: Strokes in VaD

Alzheimer's and vascular dementia (VAD) frequently co-exist.
The main evidence for VAD is based on clinical or radiological evidence for stroke.

In brief: Not many

Clinically, alzheimer's tends to be a smooth decline over time, while vascular dementia declines in steps, as small regions of the brain lose function.
Neuropsychological testing may lend evidence for, but not prove, one cause or the other. Brain MRI may show vascular disease. A definitive diagnosis can only be made by brain biopsy (which is rarely done), or at autopsy.
