Imaging Post-Stroke Recovery Using MEG
This observational study is looking at how the brain recovers after a minor stroke. Researchers want to understand why some people experience difficulties with attention, concentration, and processing speed even after a small stroke. They will use Magnetoencephalography (MEG), a special brain scan, to measure brain activity while you do a visual naming task. You would also complete the Montreal Cognitive Assessment (MOCA), a test of thinking skills. The study aims to see how brain activity changes over time to better understand recovery up to 12 months after a stroke. They are looking for adults aged 18 to 100 who have had a recent minor ischemic stroke and can speak English.
- Study design
- This is an observational study planning to include 55 participants. It compares people who have had a minor stroke with similar healthy individuals.
- What's involved
- You would have MEG scans at the University of Maryland at approximately 1 month and 6 months after your stroke. You would also complete a visual naming task and the MOCA test during these visits.
- Compensation
- Not stated in the trial record.
- Follow-up
- Your brain activity will be measured using MEG at up to 10 weeks, 6 months, and 12 months after your stroke.
