What Doctors Aren't Talking About With Our Brains, Guts, & Parkinson's: Martha Carlin
by Kevin Danielson July 15, 2025
We've been told Parkinson's is just a dopamine problem. It’s not.
This week on the podcast, we’re joined by Martha Carlin—systems thinker, microbiome expert, and someone who has spent the last 20+ years trying to understanding the brain and the gut after her husband’s Parkinson's diagnosis in his 40's. ⠀ In Part 1 of this series, we go beyond what doctors are asking—and dig into what really matters for our brains: stress, the microbiome, mineral balance, and a newly discovered protective layer you’ve never heard of (but need to know about).
When discussing gut health, the conversation usually centers on the microbiome. While balancing gut bacteria remains essential, cutting-edge science highlights another critical component of cellular health: the glycocalyx.
When discussing chronic neurological conditions like Parkinson’s disease, conventional medicine frequently focuses on a single narrative: dopamine depletion. While managing neurotransmitters remains a core part of traditional care, emerging physical chemistry and microbiome research reveal a far broader picture.
Every stressful experience sends signals throughout your body. Your heart rate changes. Your hormones shift. Your immune system responds. And one of the first places these signals arrive is in your gut.
