Scientists Studied People With Dementia Before 65—One Link Kept Appearing
Summary
A new study found that people with epilepsy have a higher chance of developing young-onset dementia, which is dementia diagnosed before age 65. The research looked at health records in France and Sweden and showed a strong link between epilepsy and this form of dementia, but it does not prove that epilepsy directly causes dementia.Key Facts
- The study analyzed health data from France and Sweden, comparing thousands of people with young-onset dementia to those without.
- 12.5% of people with young-onset dementia in France had epilepsy, compared to 1.2% without dementia.
- In Sweden, similar patterns confirmed the link between epilepsy and young-onset dementia.
- Researchers followed adults aged 30-55 with new epilepsy diagnoses for up to 10 years.
- 2.2% of new epilepsy patients developed young-onset dementia, versus 0.2% of people without epilepsy.
- After adjusting for other risks (like stroke or brain injury), new epilepsy patients were six times more likely to develop young-onset dementia.
- The study cautions that epilepsy might be an early symptom of brain degeneration rather than a cause, and cognitive issues in epilepsy patients may not always mean dementia.
- Young-onset dementia affects people during working age and can be especially challenging due to its impact on family and work life.
