Neuronal correlates of maladaptive coping: an EEG-study in tinnitus patients.

Bottom Line: Based on resting state EEG recordings, coping related differences in brain activity and connectivity were found.Correlation analysis revealed that the changes in the DLPFC correlate primarily with maladaptive coping behavior, whereas the changes in the sgACC correlate with tinnitus severity and depression.Our findings are in line with previous research in the field of depression that during resting state a alpha band hyperconnectivity exists within the default network for patients who use a maladaptive coping style, with the sgACC as the dysfunctional node and that the strength of the connectivity is related to focusing on negative mood and catastrophizing about the consequences of tinnitus.

ABSTRACT
Here we aimed to investigate the neuronal correlates of different coping styles in patients suffering from chronic tinnitus. Adaptive and maladaptive coping styles were determined in 85 tinnitus patients. Based on resting state EEG recordings, coping related differences in brain activity and connectivity were found. Maladaptive coping behavior was related to increases in subjective tinnitus loudness and distress, higher tinnitus severity and higher depression scores. EEG recordings demonstrated increased alpha activity over the left dorsolateral prefrontal cortex (DLPFC) and subgenual anterior cingulate cortex (sgACC) as well as increased connectivity in the default (i.e. resting state) network in tinnitus patients with a maladaptive coping style. Correlation analysis revealed that the changes in the DLPFC correlate primarily with maladaptive coping behavior, whereas the changes in the sgACC correlate with tinnitus severity and depression. Our findings are in line with previous research in the field of depression that during resting state a alpha band hyperconnectivity exists within the default network for patients who use a maladaptive coping style, with the sgACC as the dysfunctional node and that the strength of the connectivity is related to focusing on negative mood and catastrophizing about the consequences of tinnitus.

Scree plot for the THQ shows the number of components and the corresponding eigenvalues (see Figure 1).When the drop ceases and the curve makes an elbow toward less steep decline, all further components after the one starting the elbow can be dropped. The scree plot indicates that three factors would be ideal.

pone-0088253-g001: Scree plot for the THQ shows the number of components and the corresponding eigenvalues (see Figure 1).When the drop ceases and the curve makes an elbow toward less steep decline, all further components after the one starting the elbow can be dropped. The scree plot indicates that three factors would be ideal.

Mentions: Factor analysis using principal component extraction was performed on the TCSQ. A scree plot indicates that three factors would be ideal (Figure 1). The first factor explained 20.75% of the total variance (eigenvalue = 8.09), a second factor explained 12.95% of the total variance (eigenvalue = 5.05) and a third factor 6.58% of the total variance (eigenvalue = 2.57). Table 3 presents the factor pattern matrix after oblique rotation. Similar to previous research using the same questionnaire [8], [26], factor 1 corroborates with maladaptive coping behavior, factor 2 with active coping behavior, and factor 3 with passive coping behavior. These three factors show a good internal consistency measured with Cronbach α coefficient: maladaptive coping behavior (α = .88), active coping behavior (α = .76), and passive coping behavior (α = .69).
