Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.

Summary

This study examines a rare brain disease called anti-LGI1 encephalitis, where the immune system attacks a protein in the brain, causing memory loss, confusion, and seizures. Researchers will review medical records from 112 patients across five hospitals in Eastern China to see how often the disease returns or causes lasting problems. The goal is to identify factors that raise the risk of relapse or poor recovery, which could lead to better long-term care strategies.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could help doctors identify which patients need closer monitoring and longer treatment to prevent relapses and improve long-term quality of life.
What could go wrong
This is an observational study looking back at medical records, so it cannot prove cause and effect. Results may not apply to all patients with this rare condition.
