Motor Phenomena Associated With Leucine-Rich Glioma-Inactivated (LGI1) Emi-Encephalitis

LGI1 encephalitis is a rare immune-mediated brain disorder. Its typical features include faciobrachial dystonic seizures (FBDS), startle reactions, chorea, myoclonus, atypical parkinsonism, cogni­tive impairment, and personality changes. We report the case of a 57-year-old woman presenting with dist...

Descripción
Sumario:LGI1 encephalitis is a rare immune-mediated brain disorder. Its typical features include faciobrachial dystonic seizures (FBDS), startle reactions, chorea, myoclonus, atypical parkinsonism, cogni­tive impairment, and personality changes. We report the case of a 57-year-old woman presenting with distinct patterns of involuntary movements, including faciobrachial dystonic spasms, dyskinetic movements, and chorea. Magnetic resonance imaging (MRI) and tests on blood and cerebrospinal fluid (CSF) demonstrated encephalitis involving the right temporal lobe and caudate nucleus and associated with LGI1-antibody. LGI1 encephalitis may present with simultaneous distinct patterns of movement disorders depending on the cortical and subcortical structures involved in the disease.
