One day, you forget where you put your keys. Next, you're walking into a room and can’t remember why. And maybe the worst part? You start to wonder if this is just part of getting older.
But what if it’s not?
In this episode, Dr. Josh Helman explains why brain fog, forgetfulness, and mental fatigue hit harder after 40 and what you can do to fight back.
He’s not just an MD. Dr. Josh is a Harvard-trained biochemist and emergency medicine physician who now helps people reverse Alzheimer’s and reclaim their mental clarity. His message? It’s not too late. And the decline isn’t inevitable.
We talk about why your sleep quality, not just the number of hours, quietly shapes your brain’s future. We get into the sneaky role of inflammation and gut health, why environmental toxins are slowly hijacking our minds, and the powerful but often overlooked link between stress and dementia risk.
And Dr. Josh doesn’t stop at theory. He gives you the exact supplements he recommends (including creatine), the detox routines that actually work, and why donating blood might just save your brain.
Whether you’re worried about your own cognitive health or caring for a parent who’s slipping, this episode is your action plan.
Because aging doesn’t mean losing who you are.
