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