Better aftercare may reduce the affects of post-stroke dementia, according to a report published in the online Lancet Neurology.
The conclusion follows a review by Sarah Pendlebury and Peter Rothwell at Oxford University’s Stroke Prevention Research Unit of studies published between 1950 and May this year.
They found that multiple strokes and the complications and characteristics of the stroke itself are more important predictors of post-stroke dementia than underlying vascular risk factors, and that the burden of dementia can be reduced by providing the best possible stroke care and secondary prevention measures.
The findings show that dementia rates range from 7.4% in population studies where pre-stroke dementia is excluded to 41.3% in hospital studies where pre-stroke dementia is included.
Most of the variance is explained by differences in factors such as setting and case mix.
