The DISCOVERY study aims to understand why some people experience changes in their thinking and memory (cognitive abilities) after a stroke. Researchers want to identify factors that contribute to post-stroke cognitive impairment and dementia (a decline in memory and thinking that affects daily life). This study is observing 8,000 patients who have had an ischemic stroke (blood clot in the brain), intracerebral hemorrhage (bleeding in the brain), or aneurysmal subarachnoid hemorrhage (bleeding around the brain). The main goal is to see how a person's diagnosis of post-stroke cognitive impairment and dementia changes over 48 months. This information could help doctors better identify patients at risk and develop future treatments.

Study design

This is an observational study involving 8,000 participants. It is designed to look at a large group of people over time.

What's involved

You would have a blood draw and complete thinking and memory tests at the start. You would also have in-person follow-up visits at 3-6 months and 18 months, and annual phone calls for the study's duration.

Compensation

Not stated in the trial record.

Follow-up

Participants will be followed for up to 48 months after their stroke to assess changes in thinking and memory.
