Brain health is a public health issue, not a wellness one
By Neureka Team
If you spend time online, you might come away thinking that brain health is something you optimise. There are nootropics. There are protocols. There are stacks. There are people in their late 30s spending hundreds of dollars a month to improve their focus and memory and decision-making, and there are companies happy to sell them what they need.
This is all fine. It is also missing the point.
Brain health is a public health issue. The framing matters because the most important problems in brain health are not the problems of the worried-well. They are population problems.
The actual problems
If you look at where brain health goes wrong at scale:
- Dementia affects 55 million people worldwide today, projected to more than triple by 2050
- Stroke is the second leading cause of death globally and the leading cause of long-term disability
- Depression affects an estimated 280 million people
- Anxiety disorders another 300 million
- Traumatic brain injury causes roughly 70 million new cases a year
- Cognitive impairment in the late stages of HIV, malaria, and chronic infections affects tens of millions in regions where the conditions are common
These are not problems that get solved by nootropic stacks. They are solved, where they are solved, by the same things that solve other public health problems: blood pressure control, education, vaccination, social care, accessible diagnosis, treatment infrastructure.
Why the wellness framing took hold
A few reasons:
- The wellness industry is commercial. It makes money. Public health does not.
- Brain health has a strong individual narrative. People feel their own thinking, so they reach for what they can do themselves.
- Public health works slowly. It is hard to tell a satisfying story about lowering systolic blood pressure across a country.
- The wellness framing reaches the people who are already pretty healthy. Most brain health problems sit outside that group.
What changes when you reframe
Treating brain health as public health changes what you care about:
- You care about access, not optimisation. The question is not whether elites can buy slightly better cognition. It is whether populations can avoid catastrophic loss of it.
- You care about prevention earlier in life. The risk factors for dementia at 75 are mostly set by behaviours and exposures across decades.
- You care about diagnosis. The biggest gap in dementia care globally is not treatment. It is recognition.
- You care about the upstream causes: hypertension, hearing loss, education, environmental toxins, sleep, social isolation.
This is the version of brain health we are building toward at Neureka. It is the slower and harder version, but it is the one that matters at scale.
A note on the personal level
None of this means individuals should not take their brain health seriously. They should. But the highest-yield personal interventions are usually the boring ones: exercise, sleep, blood pressure, hearing, social connection, education. None of these require a subscription.
If you are tracking your brain, the most useful thing to track is whether you are doing the boring stuff.
