About this trial
Anti-leucine-rich glioma-inactivated 1 (LGI1) encephalitis has been increasingly identified as the second most common type of autoimmune encephalitis after anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis. It presents with acute or subacute onset of epileptic seizures, anterograde amnesia, behavior disturbances, sleep disorders and hyponatremia. In most patients with anti-LGI1 encephalitis, immunotherapy is successful in treating the encephalitis. However, relapses, chronic epilepsy, cognitive declines and psychiatric problems have been reported in some cases.
So far, prospective studies to evaluate its clinical outcomes still remain limited. In this project, the investigators will use clinical features and advanced paraclinical examinations to prospectively investigate the clinical outcomes and the associated factors in patients with anti-LGI1 encephalitis.

Trial groups
Trial outcomes
Primary outcomes
seizure outcomes
The incidence of different seizure outcomes and associated factors will be analyzed.
Clinical severity and recovery 1
modified Rankin scale, ranging from 0-6, higher scores mean a worse outcome
Clinical severity and recovery 2
clinical assessment scale for autoimmune encephalitis, ranging from 0-27, higher scores mean a worse outcome
Incidence of recurrence
a relapse of encephalitis
Secondary outcomes
Memory assessment 1
the Wechsler Memory Scale, high score means a good memory.
Memory assessment 2
Rey Auditory Verbal Learning Test (RAVLT), high score means a good vebal episodic memory.
Brain volume
with 3T magnetic resonance imaging (MRI), volumes of the whole hippocampus, hippocampal subfields and other relevant regions were determined using FreeSurfer. The unit of volume is described as mm3.
