Summary

Repetitive transcranial magnetic stimulation (rTMS) has shown to be a promising technique for improving insomnia symptoms and sleep quality. However, the impact of circadian rhythmicity on rTMS sessions and its potential influence on insomnia therapy remains unclear. Moreover, the effect of rTMS on objective sleep parameters is not fully established. The objective of this pilot study is to establish key feasibility and preliminary data that would be used for an R-level grant application focused on optimizing rTMS therapy for insomnia. The investigators will acquire feasibility data from ten adults with Insomnia disorder. Participants will receive ten sessions rTMS over two weeks, either in the morning or evening. Sleep parameters will be assessed before, during, and after completion of rTMS and brain cortical excitability will be collected before rTMS treatment. The investigators aim to 1) evaluate the impact of circadian timing of rTMS sessions on subjective and objective sleep outcomes, 2) assess the time course of improvements in sleep outcomes, and 3) examine the association between sleep outcomes and cortical excitability. The overarching goal of this work is to optimize rTMS therapy for insomnia by investigating the impact of circadian timing on rTMS sessions and assessing potential variations in subjective and objective measures of sleep.

Repeated Transcranial magnetic stimulation (rTMS)

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.
