What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests whether a 21-minute meditation practice called Shambhavi Mahamudra Kriya can enhance brain health and influence cognitive and physical well-being. Participants will either practice this meditation or maintain their usual routines while completing surveys. The trial seeks individuals living in Massachusetts who do not regularly meditate and have no history of severe mental health issues or brain-related conditions.

As an unphased trial, this study provides a unique opportunity to explore meditation's potential benefits on brain health.

Will I have to stop taking my current medications?

The trial requires that you are not currently using cognition enhancing drugs or being managed for chronic pain. If you are taking these types of medications, you may need to stop them to participate.

What prior data suggests that this meditation practice is safe?

Research has shown that Shambhavi Mahamudra Kriya, a 21-minute meditation practice, is generally safe and easy to perform. Studies found that people who practiced it daily for six weeks experienced reduced stress and improved overall health. This suggests the meditation practice is unlikely to cause harm or negative effects. In fact, it appears to enhance well-being. No reports of serious side effects exist, making it a safe choice for those interested in meditation for brain health. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Shambhavi Mahamudra Kriya is unique because it combines specific breathing patterns with meditation in a short, 21-minute routine designed to enhance brain health. Unlike conventional treatments that might involve pharmaceuticals or lengthy therapy sessions, this meditation-based approach offers a non-invasive, holistic alternative. Researchers are excited about its potential to improve cognitive function and mental well-being without the side effects associated with medication.

What evidence suggests that Shambhavi Mahamudra Kriya is effective for brain health?

Research has shown that Shambhavi Mahamudra Kriya, a 21-minute meditation practice, can benefit brain health. In one study, participants felt less stressed and noticed an improvement in their overall well-being after practicing for six weeks. Another study suggested that this meditation might improve brain health and even make the brain seem younger. The stress-reducing effects of Shambhavi Mahamudra Kriya lasted for up to a year. In this trial, participants in the "Wellness and Meditation-Based Intervention" arm will practice Shambhavi Mahamudra Kriya, while the control group will continue their daily routine. These findings suggest that this meditation practice could help improve both mental and physical functions. ^{1 6 7 8 9}

Kapalbhati pranayam significantly affects heart rate variability (HRV), indicating a shift towards sympathetic activation and parasympathetic withdrawal during and after practice, which suggests an energizing effect.

While there were notable changes in HRV, brain wave activity showed only insignificant changes, except for an increase in gamma wave activation post-pranayama, which may indicate improved control of the brain's default mode network.

Long-term meditation practice in individuals with mild cognitive impairment (MCI) or mild Alzheimer's disease (AD) resulted in significant increases in cortical thickness and gray matter volume in key brain areas associated with executive function and memory, suggesting potential neuroprotective effects.

The study, which involved detailed clinical assessments and high-resolution MRI scans over 6 months, found that meditators showed greater improvements in brain structure compared to non-meditators, particularly in regions vulnerable to neurodegeneration.

Both dhāraṇā (meditative focusing) and ekāgratā (focusing without meditation) significantly improved attention scores in a group of 60 healthy male volunteers aged 17 to 38, indicating that both practices can enhance attention.

However, dhāraṇā led to better performance in the digit symbol substitution test, suggesting it may be more effective for improving incidental learning and accuracy compared to ekāgratā.

A systematic review of 83 studies involving 6703 participants found that 8.3% experienced adverse events (AEs) related to meditation, with higher prevalence in observational studies (33.2%) compared to experimental studies (3.7%).

The most common adverse events included anxiety (33%), depression (27%), and cognitive anomalies (25%), indicating that meditation can lead to negative effects, even in individuals without prior mental health issues.

The Meditation on Twin Hearts (MTH) led to immediate cognitive improvements in nonmeditators, as evidenced by increased P300 amplitude, indicating enhanced cognitive processing after the meditation.

Experienced meditators showed shorter peak latency in brain responses compared to nonmeditators, suggesting that long-term practice of MTH may lead to more stable and efficient cognitive processing.

A systematic review of 94 randomized controlled trials involving 8,430 participants found that yoga is as safe as usual care and exercise, with no significant differences in serious adverse events or dropouts due to adverse events.

While yoga had a higher occurrence of nonserious adverse events compared to psychological or educational interventions, the overall safety profile suggests that it is a viable therapeutic option, highlighting the need for better reporting of safety data in future studies.

Long-term practice of Sahaja Yoga Meditation is linked to increased grey matter volume in the brain, particularly in areas associated with attention, self-control, and compassion, based on a study of 23 experienced meditators compared to 23 non-meditators.

Meditators showed larger grey matter volume in several right hemispheric regions, indicating that regular meditation may lead to structural brain changes that enhance cognitive functions related to emotional regulation and awareness.
