What You Need to Know Before You Apply

What is the purpose of this trial?

This trial will test if a 21-minute meditation called Shambhavi Mahamudra Kriya can improve brain health and overall well-being. The study targets people interested in better brain function and reduced stress. The meditation uses specific breathing and meditation techniques to help achieve these benefits. Shambhavi Mahamudra Kriya is a multicomponent breath-based yogic practice that has been shown to reduce perceived stress and improve general well-being after regular practice.

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.

Is meditation generally safe for humans?

Meditation is generally considered safe for most people, but some studies have reported potential side effects, including mental health issues. It's important to be aware of these risks and consult with a healthcare provider if you have concerns. ^{1 2 3 4 5}

How is the treatment Shambhavi Madamudra Kriya different from other treatments for brain health?

Shambhavi Madamudra Kriya is a meditation practice that may help improve brain health by reducing stress, which is a factor in neurodegeneration and Alzheimer's disease. Unlike other treatments, it focuses on meditation's potential to enhance cognitive function and well-being, similar to Kirtan Kriya, which has shown benefits like improved memory and reduced anxiety. ^{6 7 8 9 10}

What data supports the effectiveness of the treatment Shambhavi Madamudra Kriya for brain health?

Research shows that meditation can lead to positive changes in brain areas related to attention, memory, and executive function, which are important for brain health. Studies on similar meditation practices have found improvements in memory, reduced stress, and increased brain volume in areas at risk in neurodegenerative diseases. ^{6 8 11 12 13}

Published Research Related to This Trial

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.

Increased Grey Matter Associated with Long-Term Sahaja Yoga Meditation: A Voxel-Based Morphometry Study. Hernández, SE., Suero, J., Barros, A., et al.[2023]

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.

Kirtan Kriya (KK) meditation, which takes only 12 minutes a day, has been shown to improve memory and cognitive function in individuals at risk for Alzheimer's disease, including those with mild cognitive impairment and stressed caregivers.

KK meditation not only enhances cognitive abilities but also positively affects overall well-being by improving sleep, reducing anxiety and depression, and promoting immune function, making it a valuable tool in Alzheimer's disease prevention strategies.

In a study involving 11 healthy individuals, chanting meditation was linked to increased blood flow in the right temporal lobe and posterior cingulate gyrus, suggesting enhanced brain activity in these areas during meditation.

The findings align with previous research on meditation and support anecdotal reports of positive effects, indicating that this practice may lead to beneficial changes in brain function.

Meditation is associated with measurable changes in brain activity, including increased theta and alpha waves, which relate to the practitioner's skill level, indicating its potential for enhancing cognitive functions.

Neuroimaging studies show that meditation increases blood flow in specific brain regions, particularly the anterior cingulate cortex and dorsolateral prefrontal areas, suggesting its effectiveness in improving attention and emotional regulation.

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.

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 study aimed to compare brain activity patterns, specifically resting EEG, BAER, and P300 responses, between trained practitioners of Sudarshan Kriya (SK) and regular practitioners, as well as a control group.

This research could provide insights into how Sudarshan Kriya may influence brain function and auditory processing, potentially highlighting its benefits for mental health and cognitive performance.

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.

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.
