The goal of this study is to gain a better understanding of why some individuals who have suffered a stroke experience post-stroke cognitive decline. Specifically this study is testing whether global disruption of the blood-brain barrier detected at the time of the stroke is informative about the risk of post-stroke cognitive decline over the next 3 years.
It is well known that ischemic stroke is a risk factor for developing dementia. Prior studies have shown that after a stroke, there can be a change in the trajectory of cognitive performance with acceleration of decline. The mechanism of this phenomenon has not been established. It is known that vascular changes in the brain, referred to as cerebral small vessel disease, are associated with cognitive decline and dementia. Cerebral small vessel disease is readily seen on MRI scans of the brain, and the larger the burden of these findings, the higher the risk of cognitive deficits. Disruption of…
