Abstract
|
|
|
Limbic encephalitis (LE) is characterized by short-term memory loss, disorientation, agitation, seizures, and histological evidence of mesial temporal lobe inflammation. Leucine-rich, glioma inactivated 1 (LGI1) is the autoantigen associated with limbic encephalitis that was previously attributed to voltage-gated potassium channels. We report herein a 54-year-old female with LGI1-related limbic encephalitis who presented with recurrent episodes of episodic memory impairment, depressive mood, and phantosmia. Her symptoms dramatically improved with steroid therapy.
