Dementia is a neurological disease that is associated with aging. The incidence and prevalence of dementia is increasing as the population continues to age. The two most common forms of dementia are Alzheimer’s disease (AD) and vascular dementia (VaD). Although these two forms of dementia represent different pathologies and different clinical presentations, they share similar risk factors. It is important to distinguish between the two forms of dementia because of the differing treatments, and because the risk factors for each are often preventable. This article will discuss the classification, risk factors, and diagnosis of AD and VaD, and present distinguishing characteristics between them.
