As shown on the slide, the rates of dementia in the first year after stroke ranged as high as 41.3% (in hospital-based studies of recurrent stroke in which pre-stroke dementia was included).1 The factors associated with dementia after stroke are similar to those associated with dementia before stroke, and include older age, and female sex.1
