Episode notes

Brain health problems rarely begin where most people look. Memory issues, low mood, poor focus, anxiety, and even early cognitive decline can be driven by hidden inflammation and root-cause imbalances long before they show up the way most people expect.

In this episode, Dr. Eboni Cornish explains how chronic infections, mold, toxins, hormones, gut dysfunction, and oral or nasal microbial imbalances can all affect the brain, and why “mental health” often needs to be approached as brain health first.

She also shares how tools like brain imaging, inflammation markers, and functional testing can uncover patterns that are often missed in standard workups, while outlining the core foundations that support long-term brain health, including sleep, exercise, omega-3s, vitamin D, hormone balance, gut health, and detox capacity.
