Abstract

In summary, the interaction between vascular changes and Alzheimer's disease is a critical question that remains to be fully elucidated. On the basis of the evidence to date, it is logical to assume that any given individual with dementia might have some degree of vascular pathology and some degree of Alzheimer's disease pathology. Current diagnostic paradigms do not go far enough in terms of differentiating underlying pathologies; only brain imaging, MRI in particular, can reveal subsymptomatic cerebrovascular changes. Similarly, there are scant evidence-based data to guide clinicians in the treatment of vascular dementia or mixed dementia that might be primarily a result of, or worsened by, vascular pathology. The existing data do suggest that preventing further cerebrovascular disease, whether silent or symptomatic stroke or small vessel disease, is one clear strategy for intervening to potentially reduce the burden of cognitive impairment and dementia.
