Quantitative electroencephalography patterns in patients suffering from tinnitus.
We conducted this study in an attempt to determine whether the electroencephalographic activity in patients suffering from tinnitus exhibits tinnitus-typical electroencephalography features. Our results indicated a significant increase in the average total power in female tinnitus patients and a significant decrease in average total power in male tinnitus patients. Furthermore, we noted a suppression of the alpha peaks or a split alpha band (or both). The reactivity of the alpha frequency was employed to evaluate the efficacy of noise generators, a critical component of tinnitus-retraining therapy. In conclusion, tinnitus-typical electroencephalography features can be extracted from the electroencephalogram.
