Conspiracy theories abound throughout history, especially in times of crisis, such as the worldwide Covid-19 pandemic. People who believe these theories often have a sense of existential threat: a perceived danger to one’s own life or well-being. People then consume, believe, and share these theories as a way of making sense of that threat.
Dementia is a progressive loss of cognitive function, marked by memory problems, trouble communicating, impaired judgment, and confused thinking. Dementia most often occurs around age 65 and older but is a more severe form of decline than normal aging. People who develop dementia may lose the ability to regulate their emotions, especially anger , and their personalities may change.
The Link Between Conspiracy Theories and Dementia
Conspiracy Theories and Dementia are deeply interconnected psychological phenomena. Research shows that these two conditions frequently co-occur, with each often triggering or amplifying the other.
When someone experiences conspiracy theories, it can create conditions that make dementia more likely. Conversely, managing one can significantly improve outcomes for the other.
How Conspiracy Theories Affects Dementia
The presence of conspiracy theories can impact dementia in several important ways:
- Heightened nervous system activation from conspiracy theories can intensify dementia symptoms
- Both share common underlying mechanisms in the brain's stress response systems
- Addressing conspiracy theories often leads to measurable improvements in dementia
- The combination can create self-reinforcing cycles that require integrated treatment
Practical Strategies When Dealing with Both
When conspiracy theories and dementia occur together, a combined approach is most effective:
- Seek professional assessment — get an accurate picture of how each affects you
- Address underlying causes — identify shared root causes (sleep, stress, trauma)
- Use evidence-based interventions — CBT, mindfulness, and behavioral approaches work for both
- Build support networks — social connection buffers both conditions
- Track patterns — use journaling to see how they interact in your life
