Optimizing the Timing of RTMS to Enhance the Administration of Insomnia Treatment

Transcranial Magnetic Stimulation (TMS) involves a procedure where parts of the participants brain will be non-invasively (i.e. indirectly) stimulated by magnetic pulses. These magnetic pulses induce very brief activity in brain areas underlying the TMS coil. TMS will be performed by giving repetitive pulses (rTMS). rTMS has shown promise to reduce cortical hyperexcitability and to improve subjective measures of sleep quality and insomnia symptoms in patients with insomnia disorder. The goal of this study is to optimize the impact of rTMS therapy on sleep outcomes for patients with insomnia disorder.
