Movement disorders in children with anti-NMDAR encephalitis and other autoimmune encephalopathies.

摘要

Accurate recognition of movement disorder phenomenology may differentiate children with anti-N-methyl D-aspartate receptor (NMDAR) encephalitis, autoimmune basal ganglia encephalitis (BGE), and Sydenham's chorea (SC). Three neurologists blinded to the diagnoses recorded dominant and associated movement disorders seen on videos of 31 patients with anti-NMDAR encephalitis (n?=?10), BGE (n?=?12), and SC (n?=?9). Stereotypy was only seen in anti-NMDAR encephalitis (8/10) and not in BGE and SC (P?
