Huberman Lab · Accelerate Learning & Increase Cognitive Capacity | Dr. Tommy Wood · 20 Jul 2026 podcast

Because in reality, particularly in the studies in the UK, this is done in the national healthcare system, it was for the highest risk older adults.

And so getting it in your 50s or mid 50s, which is the guidelines in the US, that yes,

to reduce shingles, absolutely, but it doesn't map onto the dementia risk age that was seen in these studies.

A final piece of this that I think is important and kind of goes beyond just the shingles vaccine is that

If you want to maintain function over long periods of time, one of the best things you can do is minimize your chances of getting really sick.

There have been several studies.

One was the adult changes in thought study done at the University of Washington in Seattle, primarily.

A similar thing was shown in the Rush Memory and Aging Project.

But basically, when you look at the same individual over time and you measure their cognitive function every few years, which these studies did,

cognitive function doesn't just decline sort of linearly or steadily with age.

It goes down, you know, a little bit on average, but the biggest decreases sort of happen stepwise after periods of significant illness.

And so, like, in the adult change of the thought study, those who'd been, you know, sick in between, you know, had a major illness in between having their cognition retested, they had a step change down, and those who were hospitalized, that step change down was even bigger.

So...

You could talk about how people maybe could have changed things in order to recover some of that function afterwards.

I think that would have been possible if we'd thought about how you might intervene.

But a major, I think it's a reason to say, if I can do as much as I can to minimize the chance that I get really sick, because what happens then is I'm,

I'm at home, I'm not receiving any stimuli, any inputs, I'm not moving, I'm not eating well.

Obviously there's all the downsides of the infection itself.

Then if I can avoid that as much as possible, then over time that could be to greater benefits, right?

Change the overall trajectory.
