Evaluating outcomes in patients with anti-LGI1 encephalitis

A Prospective Study to Evaluate Clinical Outcomes in Patients With Anti-leucine-rich Glioma-inactivated 1 Encephalitis

Observational Second Affiliated Hospital, School of Medicine, Zhejiang University · NCT06173076

This study is trying to see how patients with a specific type of autoimmune encephalitis, called anti-LGI1 encephalitis, do over time by looking at their symptoms and test results.

What this trial studies

This observational study aims to prospectively evaluate clinical outcomes in patients diagnosed with anti-LGI1 encephalitis, a type of autoimmune encephalitis. The study will recruit newly diagnosed patients during the acute stage and will utilize a variety of advanced paraclinical examinations, including blood tests, MRI, EEG, and neuropsychological assessments. By analyzing these clinical features and outcomes, the researchers hope to identify factors associated with the disease's progression and treatment response.

Who should consider this trial

Good fit: Ideal candidates are individuals who have been newly diagnosed with anti-LGI1 encephalitis during the acute stage.

Not a fit: Patients with prior neurological conditions or coexisting antibodies may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve understanding of anti-LGI1 encephalitis and lead to better management strategies for affected patients.

How similar studies have performed: While there have been limited prospective studies on anti-LGI1 encephalitis, this approach aims to fill a gap in understanding clinical outcomes, making it a novel investigation.
