简要总结

The investigators propose to expand our previous work to test whether 10 repeated administrations of the cTBS procedure over a two-week period can lead to longer-term improvements in sleep, perhaps up to 3-months. For this 3-year study, 120 people with insomnia will be recruited to participate. There will be an initial screening, with the first consent form being for the screening questions, a psychological interview, and a one night at home sleep monitoring session with our equipment. If participants pass this first phase, they will reconsent for the main portion of the study. They will then undergo a physical examination, then a week-long at-home monitoring phase where they will wear a wristwatch sleep monitor as well as wear a portable brain wave monitor to bed each night to record sleep. Participants will continue to use this equipment throughout the treatment phase and for one week post treatment. After the first monitoring phase, each participant will be randomly assigned to one of four different conditions (i.e., 30 assigned to each group). Three of the conditions will involve cTBS focused on different brain locations (i.e., stimulation to the middle front, middle back, or side of the skull), while the fourth condition will provide inactive sham stimulation as a control. All participants will complete 10 treatment visits to the lab over two-to-three weeks, during which they will get a brief cTBS or sham stimulation each time. In addition, all participants will complete a brain scanning and cognitive testing session at the beginning and end of the two-to-three week treatment period. Participants will also complete 1-month and 3-month online follow-up assessments to examine long-term effects.

详细描述

Phase 0: Screening and Rule-Outs:

During the REDCap Screening, participants will first read this informed consent form and sign it electronically on REDCap to proceed. To begin the screening questions, they must pass a 10-question comprehension check with questions regarding this document to ensure you understand the study. They will then answer a series of questionnaires related to demographics and health background. The REDCap screener will automatically end the survey if they indicate any exclusion. If you are included in the study, at the end of the screening questions it will indicate so and that we will be in contact with you shortly. They will then undergo a virtual psychological interview to determine if they indeed have Insomnia to qualify for the study. Then, they will be mailed WatchPAT monitoring equipment for them to utilize for one night of sleep monitoring at home. This device will measure their level of Obstructive Sleep Apnea, excluding them if they score >15 AHI. We will review all of this data, and if they are eligible, participants will move on to Phase 1 of the study and undergo a second consent form.

Phase 1 In-Person Screening/Enrollment, Pre-Intervention:

Individuals who are eligible for this study after the three screening points will come into the lab to undergo an informational briefing and physical screening appointment. At this appointment, potential participants will complete the main consent for the rest of the study and get to ask any additional questions they have in person. Then, they will undergo a physical examination with a physician to determine eligibility. During the physical examination, there will be a collection of vital signs, EKG, and urine samples to screen for pregnancy and drugs (Ketamine, cocaine, MDMA, phenylcycline (PCP), and amphetamines). We will not be excluding for marijuana. In addition, individuals will complete evaluations to assess intelligence and cognition. If an individual is physically eligible and wishes to move forward, they will then be sent home and asked to complete 7 days of at-home sleep monitoring. This will include wearing an actigraph and a MUSE headband every night, while completing daily sleep diaries and short surveys every morning.

排除标准

  • Presence of any metal implant or medical device that may pose a safety risk for MRI or TMS (permanent hearing aids, cochlear implants, medication infusion devices, brain stimulation devices, permanent retainer, etc.)
