Dr. Maroon received an athletic scholarship to Indiana University in Bloomington, Indiana where as an undergraduate, he was named a Scholastic All-American in football. Dr. Maroon has successfully maintained his personal athletic interests through participation in 9 marathons and more than 72 Olympic-distance triathlon events. However, his greatest athletic accomplishment is his participation in 8 Ironman triathlons (Hawaii – 1993, 2003, 2008, 2010, 2013; Canada – 1995; New Zealand – 1997; Germany – 2000), where he usually finishes in the top 10 of his age group. Recently, in July 2012 and 2013, he finished second and third, respectively, in his age group in the Muncie, Indiana half Ironman triathlon. In October 2013 he completed his 5th World Championship Ironman in Kona, Hawaii.Neurosurgeon Dr. Joseph Maroon Interview on VITAL SIGNS about Health Living

Highlights of video interview SEE VIDEO CLICK HERE – At age 41, from the heights of career success as a brain surgeon, Dr. Joseph Maroon’s life was reduced to flipping burgers at a gas station, becoming overweight, and getting divorced. Yet had it been otherwise, he may not now be blazing a trail in the search for a cure for Parkinson’s disease. Maroon, now 84, attributes a string of life crises, including the sudden loss of his 60-year-old father, to bringing his life to a standstill over four decades ago.
“I went from literally doing awake brain surgery on patients with tumors in eloquent parts of the brain to working in a dilapidated truck stop that my father, heavily mortgaged, bequeathed to my mother.”
Suffering this “life quake,” as Maroon terms it, prompted a fierce realignment of priorities away from career success towards health, faith, and family. Recovering mental health, he says, was a result of nurturing physical health. What started as running four reluctant laps around a high school track led to triathlons, and eventually Ironman competitions. The eight-time Ironman athlete’s focus is now trained on what replenishing a key brain chemical can do to relieve Parkinson’s disease:
“We’ve been able to show in peer-reviewed journals that in Alzheimer’s and in Parkinson’s disease there’s a deficiency of glutathione in specific areas of the brain that are related to the neuropathology that occurs in these diseases.”
Through a $300,000 grant, Maroon and co-researcher Pravat Kumar Mandal will expand their glutathione research to include Navy Seals, retired special warfare combatant-craft crewmen, and retired NFL players—a cohort exposed to extraordinary head trauma and more prone to neurodegenerative diseases like Parkinson’s and Alzheimer’s. Alongside examining their levels of glutathione deficiency, Mandal and Maroon will examine the microbiomes of the participants.
“People who have a non-healthy microbiome are more subject to depressive episodes,” said Maroon. “There’s a huge gut-brain connection in mental health, disease, and depression.”
After baseline testing of memory, attention, and ability to process information, the cohort will be given gamma-glutamyl cysteine—a compound considered capable of crossing the blood-brain barrier to increase glutathione. Their brain function will be re-examined after a year to gauge the compound’s potential to counter neurodegenerative disease.
