Faith and Forgetting

I wonder if anyone has done a study on the religious affiliations of Alzheimer’s patients. I have this theory that religious belief accelerates dementia because believers actively train their brains to avoid, ignore, and disregard reality. Could lifelong religious brainwashing and denial of reality accelerate dementia?

Could Religious Indoctrination Accelerate Dementia?

What if the way we’re taught to think—or not think—in the name of faith is doing long-term damage to our brains?

It’s a question I’ve been chewing on for years. As someone who’s walked the tightrope of belief and reality, having grown up as a Seventh-Day Adventist (now an atheist) and seeing cognitive decline in those around me who are still religious, I’ve developed a theory that religious indoctrination, especially the type that demands blind faith and discourages critical thinking, may exacerbate or even accelerate neurodegenerative decline such as dementia because of how it trains the brain—for decades—to avoid truth, deny reality, and suppress cognitive dissonance.

The Core of the Theory

Religious believers—particularly those raised in high-control, fundamentalist environments—are often rewarded for:
• Accepting absurd or contradictory claims without question
• Dismissing observable facts in favor of divine dogma
• Replacing reasoning with obedience
• Suppressing internal doubt or critical thoughts
• Rejecting reality-based evidence as temptation or evil

This mental habit forms neural grooves over time—deep ruts of cognitive avoidance, inflexibility, and passivity.

Now ask yourself: what does dementia look like?
• Loss of reasoning
• Disorientation
• Cognitive rigidity
• Memory failure
• Inability to cope with new information

Sound familiar?

Cognitive Flexibility vs. Faith-Based Rigidity

A healthy brain thrives on novelty, adaptability, and challenge. We sharpen our minds by confronting tough questions, solving complex problems, and dancing with uncertainty.

But religious indoctrination often does the opposite.

In neuroscience, cognitive flexibility is the brain’s ability to adapt to new situations, learn from mistakes, and shift perspectives. Studies show this flexibility is a protective factor against neurodegenerative conditions like Alzheimer’s.

Yet religious fundamentalism has been linked to cognitive rigidity, lower openness to experience, and reduced conflict monitoring in the brain—particularly in the prefrontal cortex and anterior cingulate cortex. These are the same regions that show early decline in Alzheimer’s patients.

Are we training millions of brains to wither faster by glorifying cognitive stagnation through religious beliefs?

What the Research Says (and Doesn’t)

There’s no direct study (yet) that proves religion causes or accelerates dementia. But some findings hint at connections:
• Zmigrod et al. (2018) found ideological rigidity, including religious fundamentalism, correlates with reduced cognitive flexibility.
• Kapogiannis et al. (2009) showed that religious thought suppresses certain analytical brain regions.
• On the flip side, communal religious practices (like going to church or meditating) have been linked to slower cognitive decline, likely due to social engagement, routine, and activities.

So belief-related activities can be protective—but dogmatic, inflexible belief itself may not be. The problem is indoctrination that discourages thinking.

A Lifelong Mental Handicap?

Imagine decades of reinforced thinking patterns where critical questioning is punished, cognitive dissonance is denied, and magical thinking is normalized. By the time dementia starts knocking, there’s little neural flexibility left to fight back. The brain has been trained not to question, not to analyze, not to reflect. Just accept. Just obey.

That kind of training might feel holy, but it could also be a neurological straitjacket.

A Call for Research

Here’s what we need to explore next:
• Do people raised in reality-denying environments (e.g., young-earth creationists, anti-science religious sects) show earlier or more aggressive cognitive decline?
• Is there a neurological cost to lifelong suppression of cognitive dissonance?
• Can dogmatic belief systems be classified as cognitive risk factors for neurodegeneration?

Until then, this remains a compelling theory—one that deserves serious investigation.

Final Thoughts

This is a challenge to any system that glorifies ignorance and punishes thought. If your god demands you turn off your brain, what happens when your brain starts turning off on its own?

If cognitive health matters, maybe it’s time we start encouraging people to think freely, confront reality head-on, and nurture their minds with reason—not blind faith in religious dogma.

I would love to see this theory explored in a real research study.
