The sensitivity of anti-LGI1 encephalitis criteria was 66%, and specificity was 96%, that may lead to earlier treatment in some patients.8The sensitivity of the clinical criteria for anti-NMDARE is 49 to 50%, and specificity is 96 to 98%.75, 79Definite criteria for LE require clinical and paraclinical tests only, and despite its low sensitivity (10–38%), it is highly specific (96–98%). Here, LGI1 is linked to encephalitis.
