How COVID can change brain circuits and cause long-term brain symptoms

Understanding Circuit Dysfunction in Post-Acute Sequelae of SARS-CoV-2 Infection

NIH-funded research Yale University · NIH-11238500

This project looks at brain circuit changes in people with long COVID who have cognitive problems, mood or sleep changes, dizziness, or autonomic symptoms.

What this research studies

You would be recruited mainly from Yale's NeuroCOVID Clinic and the COVID Mind Study, joining a group of people with persistent brain-related symptoms after COVID and a group of people without such symptoms. Participants will complete standardized cognitive and mood testing and detailed symptom questionnaires. Researchers will use advanced brain imaging and connectome methods to map circuit-level brain function and relate those findings to each person's symptoms. The goal is to link specific brain circuit changes to the types of problems you experience, like brain fog, anxiety, or dizziness.

Who could benefit from this research

Good fit: People who previously had COVID-19 and now have ongoing brain-related symptoms such as memory or attention problems, new or worse anxiety or depression, sleep changes, dizziness, autonomic dysfunction, or neuropathy are ideal candidates.

Not a fit: People without a history of COVID or without ongoing neurological or neuropsychiatric symptoms are unlikely to benefit from joining this project.

Why it matters

Potential benefit: If successful, this work could help explain why long COVID causes persistent brain symptoms and point toward better diagnostics and targeted therapies.

How similar studies have performed: Prior imaging studies have shown brain changes after COVID, but using advanced connectome approaches to directly link circuit dysfunction to specific long-COVID symptoms is relatively new.
