Coffee, Tea, and Intellectual Activities Associated with Lower Dementia Risk

In Brief

Studies report associations between daily coffee, tea, cognitive activities and lower dementia risk.

Key Facts

• Consuming 2 to 3 cups of caffeinated coffee daily is associated with a reduced risk of dementia.
• One to two cups of caffeinated tea per day also show an association with lower dementia risk.
• Decaffeinated coffee does not show the same association with reduced dementia risk.
• Engaging in reading, writing, or learning new languages is associated with nearly 40% lower dementia risk.
• The global number of people living with dementia is expected to triple to over 150 million by 2050.

What Happened

Recent observational studies following nearly 132,000 people over 40 years found associations between moderate daily consumption of caffeinated coffee and tea and lower dementia risk. A separate study reported that intellectually stimulating activities such as reading and writing are associated with lower dementia risk. These findings contribute to understanding factors linked to cognitive health in later life.

Why It Matters

Dementia cases are projected to increase globally, presenting a significant public health challenge. Identifying lifestyle factors associated with dementia risk may help guide future research and public health strategies. The reported associations highlight areas for further investigation into potential preventive measures. One source advises caution regarding the coffee-dementia link, suggesting results should be interpreted with a 'massive grain of salt.'
