Brain-wave markers to predict thinking problems after a small stroke
Digital Biomarkers for Vascular Cognitive Decline in Patients with Minor Stroke
This project is seeing if patterns in brain recordings (MEG and EEG) can predict which people with small strokes will develop lasting problems with attention, thinking, or processing speed.

What this research studies
You would have noninvasive brain recordings (MEG and EEG) soon after your minor stroke and again during follow-up visits. Researchers will use deep learning to compare brain-network patterns in people who recover versus those who have lasting cognitive problems. The goal is to build a model that ultimately works with inexpensive EEG alone so the test could be used widely. If the model works, it could let doctors identify at-risk patients early and offer treatments or support sooner.
Who could benefit from this research
Good fit: Ideal candidates are adults who recently had a small (minor) ischemic stroke and are experiencing new difficulties with attention, thinking, or processing speed.
Not a fit: People with large or severe strokes, established non-vascular dementia, or those unable to undergo MEG/EEG recordings are unlikely to receive direct benefit from this project.
Why it matters
Potential benefit: If successful, this could allow early identification of people likely to develop lasting vascular cognitive problems so treatment or support can begin sooner.
How similar studies have performed: Previous MEG and EEG studies show stroke can disrupt brain networks and suggest promise, but combining multimodal recordings with deep learning to predict long-term decline is relatively new and not yet proven.
