Chewy, nutty, and packed with flavor, these pistachio cookies are a delicious way to sneak in healthy fats and plant-powered antioxidants.

And the best part? It has polyphenols that help support cellular health and combat oxidative stress!

Made with almond flour and just a touch of maple syrup, they’re naturally gluten-free and blood sugar-friendly.

Harvard researchers have uncovered a striking link between lithium levels in the brain and Alzheimer’s pathology. People with mild cognitive impairment and Alzheimer’s had significantly lower brain lithium, and those lower levels were tied to worse cognitive function.

In a mouse model, restoring lithium with low-dose lithium orotate reversed Alzheimer’s-like changes and improved memory.

This mirrors what we’ve observed in functional medicine for years, safely using low-dose lithium orotate to support cognition. While this particular study was in animals, it paves the way for human trials and highlights a promising avenue for brain health and Alzheimer’s prevention.

This could change how we approach Alzheimer’s prevention - agree or disagree? Comment below, I’m eager to hear your thoughts.

After 10 years and hundreds of conversations with pioneers, disruptors, and deep thinkers, I’m reflecting on how New Frontiers has transformed my understanding of medicine, aging, and what it really means to live well.

From exploring advanced imaging with Cleerly , to rethinking cognitive decline with Neurotrack, to mapping the future of brain health with BrainKey, this show has been a journey of connection, innovation, and clinical evolution.

Here’s to 10 years of questions that matter. And the next decade of answers we can’t wait to discover.

Early life stress does not just impact mental health. It can also affect gynecological health in profound ways.

A nationwide Swedish study of more than 129,000 women found that girls who experience childhood adversity like violence, parental mental illness, family dysfunction, or poverty are much more likely to develop endometriosis later in life.

Researchers followed these women from adolescence into adulthood and saw a clear pattern.

The more adversity a girl faced, the higher her risk of endometriosis became.

🔹 Childhood violence more than doubled the risk of endometriosis
🔹 Girls who experienced five or more adversities had a 60 percent higher risk
🔹 Even two or more adverse events raised the risk significantly

This study adds to growing evidence that early experiences can influence inflammation, immune health, and pain pathways for years to come.

We cannot separate emotional, mental, and physical health. The roots of chronic disease often begin early in life.

Researchers have introduced DunedinPACNI, an updated version of the DunedinPACE tool.
It uses just one MRI scan to estimate your biological aging rate. More than measuring brain age, this tool reflects how your whole body is aging.

The study found:
✔️ Higher DunedinPACNI scores were tied to cognitive decline, frailty, and poorer health
✔️ Changes in the brain were already showing up in midlife

We already use MRI scans every day in clinical care. DunedinPACNI could help identify people who are aging faster, long before disease or disability develops. That means more time to step in and slow the process.

This is a meaningful step toward tracking how well we are really aging.

In a 10-year study, CIMT (Carotid Intima-Media Thickness) detected over 98% of heart attacks and strokes before they happened.

We’re hosting CIMT screenings at our office in Sandy Hook, CT, on Saturday, August 16.
CIMT is a non-invasive, painless ultrasound that can detect early cardiovascular disease before symptoms appear.

Space is limited. To schedule, email frontdesk@drkarafitzgerald.com or 203.304.9502 ext 103.
