Functional and structural brain changes in anti–N‐methyl‐D‐aspartate receptor encephalitis

Abstract

Anti-NMDAR encephalitis is associated with characteristic alterations of functional connectivity and widespread changes of white matter integrity despite normal findings in routine clinical MRI. These results may help to explain the clinicoradiological paradox in anti-NMDAR encephalitis and advance the pathophysiological understanding of the disease. Correlation of imaging abnormalities with disease symptoms and severity suggests that these changes play an important role in the symptomatology of anti-NMDAR encephalitis.
