Summary

This trial is testing if 2 treatments - methylprednisolone (steroid) and human immunoglobulin (IVIG) - can help with symptoms of Long-Haul COVID in adults who had the virus at least 6 weeks ago.

Who is the study for?
Adults over 18 who had mild to moderate COVID-19 at least 12 weeks ago and are now experiencing persistent neurological symptoms like dizziness, cognitive issues, or walking difficulties. They must be willing to follow the study procedures for up to 4 months and have a brain MRI if they haven't already. People with severe psychiatric conditions, recent vaccines, certain medical treatments or conditions that could affect results are excluded.
What is being tested?
The trial is testing whether IV immunoglobulin (IVIG), compared to saline solution (a placebo), can improve long-term neurological symptoms after COVID-19 recovery. Participants will receive both treatments in different periods without knowing which one they're getting first.
What are the potential side effects?
Possible side effects of IVIG include allergic reactions, kidney dysfunction, blood clots, and low-grade fever. Saline solution is generally safe but may cause discomfort at the injection site.
