How Drinking 3+ Cups of Coffee Daily Boosts Memory in Older Women

Forgetfulness and slower recall are common concerns as we age—especially when it comes to remembering names, conversations, or where you left your keys. For older women, maintaining verbal memory can be a key part of staying mentally sharp. But could something as simple as your daily coffee or tea habit help with that?

The short answer: Yes. Drinking three or more cups of coffee or tea per day is linked to significantly less decline in verbal memory among older women, according to a long-term study featured in the U.S. journal Neurology.

The French Study on Coffee, Tea, and Memory in Seniors

Researchers from France’s National Institute of Health and Medical Research conducted a wide-ranging study on cognitive aging. They surveyed approximately 7,000 men and women with an average age of 74, living in three French cities: Bordeaux, Dijon, and Montpellier.

Participants were asked how many cups of coffee or tea they drank each day. Over the next four years, they took part in regular mental tests, including multiple word recall exercises designed to measure verbal memory specifically. These tests were repeated at the two-year and four-year marks to track changes over time.

What the Results Showed for Women

The findings were clear: older women who drank three or more cups of coffee or tea daily showed significantly smaller declines in test scores compared to those who drank just one cup per day.

The most noticeable benefit appeared in verbal memory tasks—the kind where you’re asked to remember a list of words after a short delay. This suggests that regular coffee or tea intake may help older women retain language-related memory skills as they age.

Interestingly, the researchers found no similar memory-protective effect in older men who consumed the same amounts. That difference hints that biological factors—possibly greater caffeine sensitivity in women—may play a role in how coffee impacts memory across genders.

What About Dementia Risk?

The study also looked at whether high coffee or tea consumption reduced the risk of developing dementia. However, the data showed no significant difference in dementia risk between those who drank three or more cups daily and those who drank fewer.

The researchers noted the study period might have been too short to detect any long-term protective effects against dementia. In other words, while memory retention was better in frequent coffee drinkers, the study didn’t last long enough to show whether those habits delayed or prevented serious cognitive conditions like Alzheimer’s.

Why Three Cups?

The magic number in this study was three. Participants who drank three or more cups of coffee or tea per day had the most stable memory performance over time. Those drinking just one cup didn’t see the same level of protection.

While the study didn’t explore why three cups is the turning point, it aligns with other research suggesting moderate-to-high caffeine intake may support brain function in older adults—particularly in areas related to memory and recall.

Frequently Asked Questions

Does coffee really help older women remember words better?

Yes, according to the French study published in Neurology, older women who drank three or more cups of coffee or tea per day showed less decline in verbal memory tests than those who drank just one cup. The benefit was most obvious in word recall tasks, a key part of verbal memory.

Did the study find the same memory benefits in men?

No. The research showed no memory retention advantages for older men who drank three or more cups of coffee or tea daily. The difference may be due to varying sensitivity to caffeine between men and women.

How many cups of coffee or tea were involved in the study?

Participants reported their daily intake, and the key group was those who drank three or more cups. This level was associated with better maintenance of verbal memory scores in elderly women over a four-year period.

Were there any effects on dementia risk?

The study found no significant reduction in dementia risk for people drinking three or more cups daily. The researchers suggested the study period might have been too short to detect such long-term protective effects.

Why did coffee help with verbal memory but not overall memory scores?

The study focused specifically on verbal memory—like word recall—and found benefits there. Other areas of cognitive function weren’t measured in the same way, so it’s unclear how coffee might affect broader memory or thinking skills.
