Brain MRI Longitudinal Volumetric Characteristics Associated With Outcomes of CASPR2-Limbic Encephalitis

"* Brain MRI changes in the acute stage, i.e. \< 3 months from symptoms onset, including abnormal signal intensity, altered diffusion and/or contrast enhancement in the hippocampus (unilateral/bilateral), abnormal signal intensity in basal ganglia, insula, and/or perisylvian cortex, presence of global brain atrophy, presence of hippocampal atrophy and/or MTS, hippocampal volumetry~* Brain MRI changes after acute phase resolution (\> 6 months after symptoms onset) including abnormal signal intensity in the hippocampus (unilateral/bilateral), presence of global brain atrophy, presence of hippocampal atrophy and/or MTS, hippocampal volumetry"
