Stroke care could fight dementia

The number and severity of multiple strokes is an important causal factor in post-stroke dementia, a report has claimed.

The investigation, based on a review of studies published between 1950 and 2009, found a 41.3% post-stroke dementia rate in hospital-based studies and a 7.4% rate in population-based studies where pre-stroke dementia was excluded, arguing the variance could be explained by study setting and difference in the type of cases under review.

Importantly, the authors also found that the risk of dementia was associated with the occurrence of strokes and the number of strokes rather than with underlying vascular risk factors, arguing the results showed that provision of post-stroke care could reduce the burden of dementia on hospitals and families.

The research, conducted by Sarah Pendlebury and Peter Rothwell from the Stroke Prevention Research Unit in Oxford, was published was published in Online First and The Lancet Neurology.
