However, certain features have been found to be more commonly associated with one or the other autoantibody: NMDA receptor-associated LE usually presents with seizures and psychiatric symptoms in association with ovarian teratoma in young women, VGKC antibody-positive LE presents with hyponatremia, faciobrachial dystonic seizures, amnesia and autonomic symptoms in middle-aged men, and GABA-B receptor encephalitis usually presents with psychosis, sleep disturbance and seizures in older men [12, 13]. The gene discussed is GABBR1; the disease is encephalitis.
