Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a single-center, cross-sectional study that will recruit approximately fifty seven (57) meditators and fifty one (51) controls. Individuals that have learned at least the Shambhavi Mahamudra Kriya practice and live in Massachusetts will be mailed a DREEM EEG device, and a sleepimage ring. Participants will be asked to wear the two devices while sleeping for three consecutive weekday nights (Sunday night to Thursday night) and two weekend nights (Friday and Saturday nights). While meditating during the day, participants will only wear the DREEM EEG headband. Participants will also undergo neurocognitive tests from the NIH toolbox during one virtual visit via video call. Meditators who join the study will be asked to invite a control subject to the study, matched for age and comorbidities.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Approximately one hundred and eight (108) individuals will undergo three consecutive weekday nights and two weekend nights of EEG and plethysmography recording using the DREEM headband and SleepImage rings, after answering a demographic questionnaire. Out of these 108 participants, the study will aim for 57 meditators and 51 matched controls. Only meditating participants will be asked to perform the most advanced form of meditation among the following three, which are listed from least advanced to most advanced: Shambhavi Mahamudra Kriya, Shoonya Meditation, Samyama Meditation (Breath watching). Participants will be instructed to wear the DREEM EEG headband during their practice of this meditation during each of the five days.

All participants will also be asked to undergo cognitive assessments from the NIH toolbox during a video call. The assessments from the NIH toolbox will last approximately forty-five minutes to one hour.

EEG: The participants will be mailed the DREEM devices and asked to wear them for three consecutive weekday nights and two weekend nights while sleeping. During the day, for each of these five nights, meditating participants will also be asked to wear the device while they sit still with their eyes closed, without trying to meditate, for 10 minutes. This will function as the baseline waking EEG measurement. Immediately following this, participants will be asked to perform their meditation while wearing the DREEM device for a maximum of 30 minutes.

NIH Toolbox:

This study will use select tests from the NIH Toolbox Cognition Battery and from the NIH Toolbox Emotion Battery. All of the tests together will take approximately 45 minutes to 1 hour to complete.

The selected tests from the batteries are the following:

Cognition Battery

1. Picture vocabulary test
2. List sorting working memory test
3. Picture Sequence Memory test
4. Oral reading recognition test

Emotion Battery:

1. Positive Affect CAT
2. General Life Satisfaction CAT
3. Emotional Support FF
4. Instrumental Support FF
5. Friendship FF
6. Loneliness FF
7. Perceived Stress FF

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Meditation

This is the group that will have learned at least Shamhbavi Mahamudra Kriya before they are enrolled in the study.

DREEM EEG Device

Intervention Type DEVICE

The DREEM EEG device will be used to measure brain age.

SleepImage Ring

Intervention Type DEVICE

The SleepImage ring uses plethysmography to analyze sleep architecture and cardiopulmonary coupling.

Control

This is the group that will not have learned Shambhavi Mahamudra Kriya before they are enrolled in the study. They will be invited to the study by the Meditation group.
