Investigating brain fog in COVID-19 survivors

Glial activation and metabolite contributions to 'brain fog' post-acute sequelae of COVID-19 (PASC)

['FUNDING_R21'] · MASSACHUSETTS GENERAL HOSPITAL · NIH-10890187

This study is looking at the brain fog some people feel after recovering from COVID-19, and it’s for those who want to understand why they might be having trouble with thinking and focus; participants will have brain scans while doing tasks to help researchers learn more about what's happening in their brains.

What this research studies

This research focuses on understanding the cognitive difficulties, often referred to as 'brain fog', experienced by individuals who have recovered from COVID-19. By using advanced neuroimaging techniques, the study aims to measure brain activity and inflammation in specific brain regions during cognitive tasks. Participants will undergo MRI-PET scans while performing tasks designed to assess their cognitive control and attention. The goal is to identify the biological factors contributing to these cognitive symptoms in post-acute sequelae of COVID-19 (PASC).

Who could benefit from this research

Good fit: Ideal candidates are individuals under 21 years old who have experienced cognitive symptoms after recovering from COVID-19.

Not a fit: Patients who have not had COVID-19 or do not experience cognitive symptoms related to PASC may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to better understanding and treatment options for cognitive impairments in COVID-19 survivors.

How similar studies have performed: Other research has shown promising results in understanding cognitive symptoms related to inflammation, making this approach both relevant and potentially impactful.
