The olfactory event-related potential (OERP) method provides a means of objectively assessing olfactory function. However, further validation is needed before OERPs can be routinely applied in clinical assessment of olfactory dysfunction. ⋯ The OERP amplitudes increased and the latencies shortened with increasing stimulus concentration. Furthermore, a difference between the groups was found, with higher OERP amplitudes and shorter latencies in healthy subjects compared with patients.
