Summary

Most of patients with autoimmune encephalitis are left with permanent cognitive deficits of varying severity. The patients' life and career would be affected definitely by cognitive deficits. Recently, more and more clinical physician have begun to focus on cognitive impairment of patients with autoimmune encephalitis. Generally, the outcome was measured by the modified Rankin Scale (mRS). However, the mRS are commonly used to evaluate the degree of disability or dependence in the daily activities of the patients suffering from a stroke and cognition function were minimally evaluated in this scale. It is crucial to adopt detailed cognition tools to study the long-term cognitive outcomes and as an indicator of overall curative effect judgment in autoimmune encephalitis. Currently, only early immunotherapy is uniformly and consistently considered to produce favorable cognitive outcomes. However, studies concerning the association of second-line immunotherapy with cognitive outcomes have been scarce and have shown conflicting results regarding autoimmune encephalitis. Hence, the goal of this study was to explore cognitive neural mechanism of autoimmune encephalitis by using neuropsychological tests and multi-mode MRIs.

Detailed description

The goal of this study was to explore cognitive neural mechanism of different types of autoimmune encephalitis by using neuropsychological tests and multi-mode MRIs. Neuropsychological tests involves the assessments of different cognitive domains. And multi-mode MRIs contains resting-fMRI, DTI and task-related fMRI.
