Clinical Trial Summary

Limbic encephalitis associated with anti leucine-rich glioma inactivated-1 LGI1 antibody (anti-LGI1) usually presents with seizures and progressive disturbance of memory and behavior. But anti-LGI1 associated encephalitis (LGI1-E) could present with a variety of features including an elective cognitive form of the disease, which mimicks a neurodegenerative condition such as Creutzfeld Jakob disease or rapidly progressive Alzheimer disease. In these patients, the appropriate diagnosis could be challenging.

The primary aim of this study is to describe cerebrospinal fluid biomarkers in a cohort of LGI1-E patients as results of these markers are currently not described in LGI1-E. Moreover, patients with LGI1-E often present seizures. At this point, the impact on cerebrospinal fluid biomarkers has not been described in this condition. The secondary aims of this study are to compare cerebrospinal fluid (CSF) biomarkers in LGI1-E patients to these in other neurodegenerative conditions ( e.g. creutzfeld Jakob disease, Alzheimer disease), which are considered as a possible differential diagnosis in these patients. The last aim of this study is to look for correlations between cerebrospinal fluid biomarkers in LGI1-E and clinical data in these patients, especially seizure.
