Rates, Risks & Routes to Reduce Vascular Dementia.



  • Prospective clinical study evaluating the development of dementia among patients with stroke over at least 2 years.
  • Stroke is a highly prevalent disease and is known to be a cause of cognitive impairment and vascular dementia. R4VaD is a UK-wide observational study of cognitive, physical and neuropsychiatric complications after stroke. Patients can experience memory, thinking or mood changes, or dementia, after a stroke but enough is not yet known about how to treat these conditions. R4VaD is looking at these conditions to help more people to make a better recovery. 

  • The aim of R4VaD is to improve our understanding of the rates of and risk factors for post-stroke cognitive impairment (PSCI), while informing patient services, intervention targets and research into mechanisms. We will use information on pre-morbid and pre-stroke cognition, medical, lifestyle and socioeconomic factors collected in our main study and via data linkage to this end. The fundamental questions are: who will develop memory and thinking problems after stroke, why does this happen, how can we treat it?
