Abstract
The presence of vascular neurocognitive impairment (whatever the severity) is always associated with a functional impact and increased risk of dependency and institutionalization. However, vascular cognitive impairment remains underdiagnosed, and the mechanisms underlying post-stroke cognitive disorders are still poorly understood. However, the advent of new criteria and a standardized international neuropsychological battery is expected to lead to improved diagnosis and management, and the development of novel techniques (such as brain imaging and amyloid PET) should improve our understanding of the mechanisms underlying vascular cognitive impairment and help to identify potential targets for therapy.
