Quantitative Electroencephalography: Preliminary Report-Tinnitus

Author(s): Abraham Shulman and Barbara Goldstein

This preliminary report is an account of 21 consecutive patients who had tinnitus of the severe disabling type and were examined with quantitative electroencephalography (QEEG). A multimetric analysis of the raw data was highlighted by an abnormal incidence of significant central nervous system electrical dysfunction identified in each patient (21 of 21). Relative power was increased or decreased in the temporal region in 10 of21 patients. Relative power was reported to be increased or decreased in temporal frontal regions in 20 of 21 patients. Coherence irregularity was identified in all 21 patients. QEEG preliminary data support the hypothesis of a final common pathway for tinnitus and the significant role of the temporal and temporofrontal regions of interest in patients with tinnitus of the severe disabling type. QEEG with multimetric analysis is considered a significant addition to the medical audiological tinnitus patient protocol as one of a battery of electrophysiological tests for the clinical identification of a predominantly central type of tinnitus.
