Brain Health: How Music and Lifelong Learning Can Prevent Cognitive Decline

In our latest Bionic Health podcast, Dr. Jared Pelo interviews neurologist-turned-entrepreneur Dr. Josh Turknett about the science of brain health, cognitive decline prevention, and how learning complex skills like music can help maintain brain function as we age.

From Neurologist to Music Education Innovator

Dr. Josh Turknett's journey is anything but conventional. After completing medical school and a four-year neurology residency at the University of Florida, he spent years in private practice treating neurological conditions. But over time, he began to recognize a significant gap between what he could offer patients in clinical practice and what he believed they truly needed.

"I came to realize that a lot of the issues I was seeing as a neurologist were related to lifestyle and preventable types of things," Dr. Turknett explains. Through his own experience with migraines, he discovered that dietary changes had a more profound impact on his condition than conventional treatments—a revelation that would eventually lead him to reconsider his entire approach to neurological health.

While still practicing neurology, Dr. Turknett pursued his passion for music, specifically the banjo. Drawing on his background in cognitive neuroscience, he began integrating principles of neuroplasticity into his musical practice. This eventually evolved into BrainJo, an innovative platform that teaches musical instruments through neuroscience-based approaches.

The "Stimulate and Support" Framework for Brain Health

When it comes to maintaining cognitive health, Dr. Turknett advocates a simple yet powerful framework: stimulate and support.

"There are two things to think about in terms of keeping a healthy brain throughout our life," he says. "We have stimulation on one side and support on the other side."

Stimulation: Fighting Autopilot Mode

Cognitive stimulation is essential for maintaining brain health, but Dr. Turknett points out that many of us, especially in established careers, operate largely on autopilot. "The more you can spend your day on autopilot, the less cognitive stimulation you've provided," he explains.

Real cognitive stimulation comes from activities that trigger plastic reorganization in the brain—essentially, learning new knowledge and skills. This is where complex activities like learning a musical instrument come in.

BrainJo currently offers instruction in multiple instruments:

• Two styles of banjo (claw hammer and fingerstyle)
• Piano
• Ukulele
• Fiddle
• With guitar coming soon

Support: Giving Your Brain What It Needs

Just as important as stimulation is providing your brain with the resources it needs to maintain existing neural connections and build new ones. Dr. Turknett identifies several key pillars of brain support:

1. Physical activity - Particularly activities that combine cardiovascular fitness, strength training, and cognitive demands (like tennis or pickleball)
2. Sleep and rest - Critical for neural recovery and consolidation
3. Nutrition - Including key nutrients like B12, vitamin D, magnesium, zinc, and copper
4. Stress management - Limiting chronic stress that can damage brain tissue
5. Social connection - Perhaps the most underappreciated factor in brain health

On the often-overlooked importance of social interaction, Dr. Turknett notes: "Being around other people, conversing with other people, being in social situations is an enormous cognitive stimulus... one of the reasons that we see [cognitive] deterioration is because of the loss of that stimulus when people are isolated."

Assessing Cognitive Risk and Monitoring Brain Health

Many people, especially those with family histories of dementia or genetic risk factors like APOE4, wonder how to assess their risk for cognitive decline. Dr. Turknett emphasizes that while there's no single test that can definitively predict risk, there are several approaches to monitoring brain health:

• Regular cognitive assessments, whether through formal testing or self-monitoring
• Basic blood work to identify conditions like metabolic syndrome or nutritional deficiencies
• Lifestyle evaluation to identify areas for improvement

He recommends foodforthebrain.org for those interested in comprehensive cognitive evaluation with a nutritional focus.

Rather than viewing cognitive health as predetermined, Dr. Turknett stresses that "we are actively influencing our risk all the time." This empowering perspective frames brain health as something we can continuously improve through our daily choices.

Anyone Can Play Music: The Science of Learning at Any Age

Dr. Turknett's new book, "Anyone Can Play Music: How to Realize Your Musical Potential with the Laws of BrainJo," challenges the common belief that learning complex skills like music becomes impossible as we age.

"The reason we can learn anything at any age is because we have this ability to change the brain at any age," he explains. "Learning complex skills relies on neurological mechanisms that we all share."

The book outlines principles for leveraging these natural mechanisms, often requiring readers to unlearn ineffective approaches taught in traditional education. It's as much about how to learn anything as it is about music specifically.

A Prescription for Brain Health

For someone in their mid-40s concerned about future cognitive health, Dr. Turknett recommends:

1. Evaluate your current cognitive stimulation - Is your work challenging your brain, or are you on autopilot?
2. Incorporate complex real-world skills - Music, dance, or sports that demand coordination and strategy
3. Ensure physical fitness - Combining low-level movement, resistance training, and occasional high-intensity exercise
4. Monitor nutritional status - Particularly for B12, vitamin D, and other brain-essential nutrients
5. Prioritize social connection - Ideally through activities that simultaneously provide cognitive stimulation

The key is finding activities you enjoy that provide both cognitive challenges and social connection—like joining a community of musicians or picking up a sport like pickleball that combines physical activity, strategy, and social interaction.

Beyond the Clinic: Making a Broader Impact

Dr. Turknett's transition from clinical practice to entrepreneurship reflects his desire to have a greater impact on brain health than the constraints of a traditional medical practice would allow.

"To actually fulfill the role that I initially signed up for... I could do a much better job doing what I'm doing now than I could in the clinic," he reflects. Through his online platform, books, and educational content, he's able to reach and help far more people than would be possible seeing patients one at a time.

This sentiment resonates with Dr. Pelo, who made a similar transition from emergency medicine to focusing on preventative health through technology. Both physicians recognize that while there will always be a need for excellent clinicians, there's also tremendous value in creating scalable approaches to health that can benefit millions.

The Science of Fun: Moving Beyond Toxic Positivity to True Enjoyment

In a compelling conversation with Dr. Jared Pelo, organizational psychologist Mike Rucker shares insights from his research on fun and explains why pursuing happiness might not be the best path to wellbeing.

From Happiness to Fun: A Paradigm Shift

Rucker's journey began as a charter member of the International Positive Psychology Association, but his perspective shifted dramatically after experiencing a series of personal challenges - losing his younger brother to a pulmonary embolism, requiring early hip replacement, and relocating away from his support network. These experiences revealed the limitations of pursuing happiness as an ideal.

"We were on the wrong path as positive psychologists," Rucker explains. "Holding up happiness as an ideal was becoming problematic. Paradoxically, anyone that kind of prescribed to that were some of the most unhappy people."

The Power of Fun as an Alternative

Instead of chasing happiness, Rucker advocates for focusing on fun and enjoyment. The key difference? Fun is action-oriented and within our control. We can choose to have fun at any moment, whereas happiness is often more elusive and circumstantial.

Research from MIT, Stanford, and Harvard supports this approach. People who deliberately make time for enjoyable activities - what Rucker colorfully calls having a "full fun cup" - are more likely to:

• Take on challenging tasks

• Approach work with greater vitality

• Think more creatively

• Handle setbacks more effectively

Practical Steps to More Fun

Rucker offers several practical approaches to incorporating more fun into daily life:

1. Create transition rituals between work and leisure time

2. Schedule deliberate breaks, including proper lunch breaks

3. Be mindful of how you spend your 168 hours per week

4. Look for "fun friends" who can model enjoyable activities

5. Transform passive leisure into active engagement

He emphasizes that about five hours of truly hedonic moments per day appears to be optimal - beyond that, people may start questioning if they're living a purposeful life.

Making Health Interventions More Enjoyable

One of the most interesting applications of Rucker's research is in health interventions. Recent studies from the University of Minnesota show that the number one predictor of success in health interventions is whether people enjoy what they're doing. This suggests that rather than focusing on optimal protocols or maximum efficiency, we should prioritize making healthy activities enjoyable.

Rucker uses cycling as an example: "There are three things if you're not enjoying something that you should look at to potentially make it more fun: the activity itself, the environment, and the people you're doing it with."

Moving Forward

The conversation concludes with a powerful reminder that while life isn't meant to be easy all the time, we have more control over our enjoyment than we might think. By being deliberate about creating opportunities for fun and adjusting our approach when activities aren't enjoyable, we can build a more sustainable path to wellbeing.

For those interested in learning more, Rucker's book "The Fun Habit" is now available through local bookstores and Amazon, and his media appearances can be found at mycorracker.com.

This discussion serves as a refreshing counterpoint to the "happiness industrial complex," suggesting that perhaps the path to wellbeing isn't through the pursuit of happiness itself, but through the deliberate cultivation of enjoyable experiences in our daily lives.
