Abstract
The following quantitative correlational study investigated the effects of eTMS on individuals with pharmacoresistant sleep disorders using a qEEG. This research measures the dimensions of anxiety, depression and quality of life (QoL) as it relates to untreated secondary diagnosis. Additionally, this research examines the activity level of the dorsolateral prefrontal cortex in relation to eTMS treatments. It was found that correlation with anxiety (rs = -.466, p < .001), depression (rs = -0.556, p < 0.001), quality of life (rs = -.436, p < .001), and sleep disturbances (rs = -0.452, p < 0.001), have a statistically significant negative correlation with dlPFC activity level. Finally, it was found that eTMS does have a statistically significant relationship with sleep disturbances as well as anxiety, depression and general quality of life (U (195) = 4647, p = .971). This is important to the field of neuroscience as it provided a more precise form of individualized neuromodulation through the use of a uncommon type of transcranial magnetic stimulation.
