The improvement of IPSS and IIEF5 scores also correlate with amplitude of MMN wave (r = −0.639; p = 0.04, and r = 0.628; p = 0.05, respectively) and there were almost significant correlations of IPSS with the other electrophysiological parameters (latency: r = 0.546, p = 0.06; and area: r = −0.368, p = 0.06).
