Poststroke Dementia and Imaging

Poststroke Dementia and ImagingStroke increases the risk of dementia by approximate 2-9 times. World wide, vascular dementia (VaD) is the second commonest cause of dementia. Presence of post-stroke dementia (PSD) reduces survival among stroke survivors and increases risk of long term stroke recurrence. Varying severity levels of cognitive impairment affects functional outcome independent of physical impairment. With an ageing population, burden of PSD is expected to rise. Although PSD is prevalent, relevant to mortality and morbidity, and is potentially more preventable than Alzheimer's disease (AD), it has received less attention relative to post-stroke physical impairment or to AD. It is not until the last decade that more attention has been paid to PSD.
