This study had several limitations. First, the precise cortical locations of significantly improved PAC values have not been determined because source analysis was not possible due to the limited number of electrodes. Therefore, the. Second, the sample size was relatively small and our findings require a larger sample size for validation. Thus, our findings should be considered preliminary and should be replicated. Future studies could use high‐density EEG to further improve spatial localization, including more subjects, and conduct more in‐depth studies on the application of PAC in ID patients, such as using baseline PAC values to predict the efficacy of rTMS in ID patients.
