LGI1 antibody encephalitis and psychosis.
OBJECTIVE:
To describe a case of leucine-rich, glioma inactivated 1 antibody-encephalitis presenting with psychosis.


METHODS:
Case report.


RESULTS:
A young man with leucine-rich, glioma inactivated 1-antibody encephalitis initially presented with acute psychotic symptoms, short-term memory loss and faciobrachial dystonic seizures. Magnetic resonance imaging revealed hippocampal lesions. Electroencephalography revealed frontotemporal slowing of background activity.


CONCLUSION:
Increased awareness of leucine-rich, glioma inactivated 1-antibody encephalitis may promote early recognition and treatment.
