Faciobrachial dystonic seizures precede Lgi1 antibody limbic encephalitis.
OBJECTIVE To describe a distinctive seizure semiology that closely associates with voltage-gated potassium channel (VGKC)-complex/Lgi1 antibodies and commonly precedes the onset of limbic encephalitis (LE). METHODS Twenty-nine patients were identified by the authors (n = 15) or referring clinicians (n = 14). The temporal progression of clinical features and serum sodium, brain magnetic resona...
متن کاملLGI1-negative faciobrachial dystonic-like seizures originating from the insula
We expand the differential diagnosis of LGI1-positive faciobrachial dystonic seizures (FBDS) by presenting a 67-year-old woman affected by seizures of similar semiology who was found to have insular epilepsy. We report the distinct characteristics of insular faciobrachial dystonic-like seizures that would help clinicians to differentiate them from typical LGI1-positive FBDS, thus, guiding thera...

OBJECTIVE To characterize the clinical features and MRI abnormalities of leucine-rich glioma-inactivated 1 (LGI1)-autoantibody (Ab) faciobrachial dystonic seizures (FBDS). METHODS Forty-eight patients with LGI1-Ab encephalopathy were retrospectively identified by searching our clinical and serologic database from January 1, 2002, to June 1, 2015. Of these, 26 met inclusion criteria for this c...
متن کاملStriking basal ganglia imaging abnormalities in LGI1 ab faciobrachial dystonic seizures
Autoimmune encephalitis associated with antibodies targeting the neuronal surface antigen leucine-rich, glioma-inactivated 1 (LGI1) protein is accompanied by faciobrachial dystonic seizures (FBDS) in up to half of patients. These hallmark episodes can be mistaken for psychiatric disorders, particularly as the ictal episodes are usually not detectable with surface EEG electrodes. Accompanying im...
متن کاملSpontaneous remission without progression to limbic encephalitis in a patient with LGi1 seropositive faciobrachial dystonic seizure
Faciobrachial dystonic seizures are pathognomonic of leucine-rich glioma inactivated-1 (LGi1) antibody, non-paraneoplastic limbic encephalitis. Faciobrachial dystonic seizures usually precede limbic encephalitis by about a month. It is unknown whether, if untreated, faciobrachial dystonic seizures inevitably progress to limbic encephalitis. We present an LGi1 seropositive patient with a year’s ...
