Case Discussion
These features are non-specific and common and represent chronic small vessel ischemic change. It used to be thought that Alzheimer's disease and vascular dementia were separate, if not exactly mutually exclusive. We now recognize that they often co-exist. As such before a diagnosis of vascular dementia can be made, a careful assessment for imaging and neurocognitive features of Alzheimer's disease should be undertaken.
