Event-related potentials (ERP) were assessed by the auditory and visual oddball paradigms. Amplitude and latency of P300 at the frontal (Fz), central (Cz) and parietal (Pz) regions were determined and compared to controls. P300 detection was performed in NPSLE patients with pre-diagnosed cognitive impairment (n=9), matched SLE patients without previous NPSLE (non-NPSLE) (n=9), and healthy controls (n=15). Auditory oddball task did not show any P300 abnormality between groups. Visual oddball task revealed reduced amplitude of P300 over Fz (p=0.002) and Cz (p=0.009) electrodes in NPSLE patients compared to healthy controls and among those who had predominant memory deficit (p=0.01 at Fz). Abnormal P300 was also observed in non-NPSLE patients at Fz and Cz. Using visual oddball paradigm, abnormal P300 was found in NPSLE patients over frontal and parietal regions compared to normal controls but was not discriminative from possible subclinical disease in non-NPSLE patients. In conclusion, visual oddball paradigm was a more sensitive electrophysiological marker than auditory oddball paradigm for cognitive impairment in NPSLE patients.
