Aspects of aging, such as specific age-related conditions, arise from shared root causes. If an individual exhibits one given outcome of aging, then they are more likely to also exhibit others that arise from the same underlying processes. Thus we should not be surprised to see that incidence of stroke is correlated with incidence of dementia. We don’t have to suggest that stroke-induced damage to the brain, and the inflammatory and other reactions to that damage, can accelerate the onset of dementia. We can instead argue that both stroke and dementia are consequences of the aging of the cardiovascular system, and there likely to occur in close proximity to one another. In fact both of these explanations are likely to be true.

A new study analysed data on stroke and dementia risk from 3.2 million people across the world, finding that people who have had a stroke are around twice as likely to develop dementia. The link between stroke and dementia persisted even after taking into account other dementia risk factors such as blood pressure, diabetes, and cardiovascular disease. Their findings
