Reading and writing can lower dementia risk by almost 40%, study finds

Summary

A study suggests that reading, writing, and learning languages can lower dementia risk by almost 40%. Researchers tracked participants over eight years, finding that higher lifetime cognitive enrichment was associated with a reduced risk of Alzheimer's and MCI.

Key Takeaways

1. Reading, writing and learning a language or two can lower your risk of dementia by almost 40%, according to a study that suggests millions of people could prevent or delay the condition.
2. Researchers found higher scores in lifetime enrichment were associated with a 38% lower risk of Alzheimer’s disease and a 36% lower risk of MCI.
3. “This new research shows that staying mentally active throughout life can cut the risk of Alzheimer’s disease by nearly 40%,” she said.

Claims (5)

• While based on a study, suggesting millions could prevent or delay the condition is an overstatement without further evidence.
• The study shows an association, not a definitive causal relationship that 'cuts' the risk.
• The article does not provide any specific findings from these autopsies, making the inclusion of this detail somewhat dubious without further context.
• This statement acknowledges the limitation of the study, but the article still frames the findings as if they are more conclusive than they are.
