Surprising Findings
The dose-response relationship — higher caffeine intake showed stronger protective effects — was clearly demonstrated in subgroup analysis.
Many assume only moderate intake is beneficial; this suggests even higher consumption (up to 300+ mg/day) may offer greater protection, which contradicts common warnings about caffeine overuse.
Practical Takeaways
If you already drink coffee, continuing 2–4 cups daily may support cognitive health as you age.

People who drink a lot of coffee or tea—more than 300 mg of caffeine a day—might see their memory problems from Alzheimer’s slow down more than people who drink very little caffeine, based on studies that track groups over time.
People who drink a lot of coffee or consume a lot of caffeine seem to have better memory and slower brain decline as they age, according to studies that watch people over time — so coffee might help keep your brain sharp without costing much.
People who drink more coffee or caffeine-rich drinks tend to forget things less quickly as they get older, and this might mean caffeine helps slow down memory problems linked to Alzheimer’s.
People who drink a moderate amount of coffee or tea may be less likely to develop dementia later in life — about 18% less likely, according to this claim.
