Brief 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.

Outcome Measures

Primary Outcomes (2)

  • Insomnia Severity Index (ISI)

    Improvement in insomnia symptoms will be assessed using the Insomnia Severity Index (ISI). ISI is a 7-item self-report questionnaire designed to assess the severity of insomnia symptoms and their impact on daily functioning. Each question is scored on a 5-point Likert scale, with ratings from 0 (no problem) to 4 (very severe problem).

    Insomnia severity index will be collected within one week before and within one week after the 10 sessions (over two weeks) of rTMS therapy.

  • Pittsburgh Sleep Quality Index

    Improvement in subjective sleep quality will be assessed using the Pittsburgh Sleep Quality Index (PSQI). PSQI is a widely used questionnaire that assesses sleep quality and disturbances over one month. It includes seven components and ranges from 0 to 21, with higher scores indicating poorer sleep quality. A score above 5 is generally considered indicative of poor sleep quality.

    Pittsburgh Sleep Quality Index will be collected within one week before and within one week after the 10 sessions (over two weeks) of rTMS therapy.

Secondary Outcomes (2)

  • OBJECTIVE SLEEP MEASURES

    EEG sleep parameters will be collected within one week before and within one week after 10 sessions (over two weeks)of rTMS therapy. Actiwatch sleep measures will be collected from one week before the baseline session to the end of the treatment session.

  • Cortical Excitability

    Cortical excitability will be measured during the first therapy session, before the first rTMS therapy.

Study Arms (2)

MORNING GROUP

EXPERIMENTAL

Five participants (21 to 45 years old) experiencing clinically meaningful insomnia symptoms will be enrolled and will receive 10 sessions of right dorsolateral prefrontal cortex (DLPFC) rTMS therapy in the morning over two consecutive weeks.

Other: Repeated Transcranial magnetic stimulation (rTMS)

EVENING GROUP

EXPERIMENTAL

Five participants (21 to 45 years old) experiencing clinically meaningful insomnia symptoms will be enrolled and will receive 10 sessions of right dorsolateral prefrontal cortex (DLPFC) rTMS therapy in the evening over two consecutive weeks.

Other: Repeated Transcranial magnetic stimulation (rTMS)

Interventions

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.
