Yoga Improves Memory and Brain Function in Older Adults, Study Finds

Yoga promotes a healthy spine, healthy brain and improved muscle strength and overall physical and mental wellbeing.

Prolonged stress can have a deleterious effect on the brain, reducing your ability to think, plan, and reason effectively. This is particularly true for the elderly. A study published in Biological Psychology (see sources below) finds that yoga may moderate the stress response and improve executive function in older adults, building on prior research that finds that yoga is good for your brain.

Neuroendocrine research finds that brain exposure to higher concentrations of cortisol – a key marker of stress – increases the risk for cognitive deficits as we age. Chronic stress magnifies this effect, placing undue wear and tear on the brain and the autonomic nervous system and increasing the risk for disease.

Yoga, which emphasizes mind-body integration, is theorized to attenuate these effects by increasing the relaxation response through activation of the parasympathetic nervous system. This, in turn, decreases cortisol levels and inflammation and returns the mind, body, and brain to a state of balance, which can enhance cognitive functioning.

Study Explores the Effect of Yoga on Memory and Cognitive Function

Mature Women practicing yoga for healthy brain and body aging and improved memory.

To test this theory, researchers randomly assigned 118 sedentary, community-dwelling older adults (mean age = 62.02 years) to either an 8-week Hatha yoga intervention (n=61) or a stretching control group (n=57). The majority of study adults were female, married, working full time, well-educated, and moderately affluent. Ethnic minorities comprised 20% of the overall sample. A proportion of the full sample had prior experience with yoga, however, none of the participants currently maintained a regular yoga practice.

Each adult in the study completed an assessment before and after the intervention consisting of self-report questionnaires measuring stress and anxiety. They were then given tests of executive function and asked to provide samples of salivary cortisol.

Members of both groups attended hour-long yoga classes 3 times per week for 8-weeks. Yoga classes were designed for beginners and led by a certified yoga instructor. Classes included “new postures, breathing, and meditative exercises”. Postures included “warrior pose, easy lotus pose, and sun salutations,” whereas breathing exercises included alternate nostril breathing. Meditative components involved focusing on “thoughts, breath, and mantra repetitions.” No mention was made of the yoga tradition informing these practices.

The stretching group attended hour-long sessions 3 times per week for 8 weeks that excluded any form of yoga postures, breathing exercises, or meditative practices. Movements included stretching and strengthening maneuvers that met the Center for Disease Control’s anaerobic recommendations. Classes included warm-up and cool-down periods and repetition of 8-10 different exercises taught by a certified personal trainer.

A total of 108 adults completed the study (attrition rate of 8.47%), suggesting that both the yoga and stretching programs were feasible. There were no differences between those who completed the intervention and those who dropped out on any of the baseline demographic or cognitive measures. Participation in the groups was relatively equivalent.

Yoga Reduces Stress and Improves Executive Function

Yoga reduces stress and improves brain function and memory research says.

At the conclusion of the 8-week intervention, yoga participants demonstrated less physiological stress (as indicated by lower concentrations of salivary cortisol) than the stretching control group, whose salivary cortisol actually increased. The yoga group also reported feeling less stress and anxiety at the end of 8 weeks.

Greater improvements in cognitive functioning at the end of training were also indicated for the yoga group compared to stretching controls. Specifically, yoga participants demonstrated significantly improved working memory capacity and cognitive flexibility relative to the control group. This is particularly encouraging news for older adults and those experiencing high levels of persistent stress, both of which are at risk for declining cognitive function.

How Yoga Benefits Mental Functioning

Yoga and Meditation have positive benefits for brain function and memory

Yoga involves the integration of physical movement with breath awareness and focused attention. Unlike most other disciplines, yoga facilitates neural communication between the brain and body and the integration of both top-down and bottom-up cognitive processing.

Top-down processing refers to conceptually driven mental events that are influenced by thoughts, expectations, values, and beliefs. When engaging in top-down processing, you use existing knowledge and seek out information and experiences that “fill in the blanks.” This allows you to use accumulated knowledge as a frame of reference rather than figuring out each situation from scratch.  It also means that you are better able to regulate emotions such as fear and anxiety.

In bottom-up processing, information from the external environment is filtered through the brain’s emotional circuitry prior to being projected to higher-order “thinking” centers for interpretation. For example, when a pedestrian steps in the path of your car, you slam on the brakes to avert an accident. It isn’t until after an accident has been averted that you interpret the details of the event. Top-down processing allows you to maintain composure while tackling complex problems. Bottom-up processing aids in your immediate survival. Both systems are necessary to maintain a healthy emotional balance.

Yoga is proposed to engage both the top-down and bottom-up systems. By coordinating breath with movement, you become increasingly more aware of the physical and mental events that shape your experience and are better able to focus and sustain attention. Try standing on one foot while solving a complex problem, and you will notice that it is very difficult to do both well. Yoga enables you to train and refine your mental energy and harness it in appropriate ways when you need to.

This ability to integrate mind and body in the service of sustained focus, self-awareness, and mental regulation may be why studies consistently find that practices such as yoga and meditation enhance cognitive capacities and impact the brain networks that enhance our capacity for mindful awareness, self-reflection, emotion regulation, working memory, cognitive flexibility, and other competencies that are key to successful living and healthy aging.  In the years to come, we will undoubtedly continue to learn how and why yoga can enable us to thrive throughout the lifespan.
