Abstract
Focal neuroinflammation is considered one of the hypotheses for the cause of temporal lobe epilepsy (TLE) with amygdala enlargement (AE). Here, we report a case involving an adult female patient with TLE-AE characterized by late-onset seizures and cognitive impairment. Anti-N-methyl-d-aspartate receptor (NMDAR) antibodies were detected in her cerebrospinal fluid. However, administration of appropriate anti-seizure drugs (ASD), without immunotherapy, improved TLE-AE associated with NMDAR antibodies. In the present case, two clinically significant observations were made: 1) anti-NMDAR antibody-mediated autoimmune processes may be associated with TLE-AE, and 2) appropriate administration of ASD alone can improve clinical symptoms in mild cases of autoimmune epilepsy.
