That morning cup of coffee may do more than serve as a quick energy boost. Early research is indicating that moderate consumption of caffeine could offer preventive effects on the brain in the long run.

Some of the most popular beverages in the world are coffee and tea, which are long treasured as morning traditions for millions of people. For some, caffeine offers increased wakefulness and focus, or comfort in ritual. But beyond its immediate effects, interest is growing in the possibility that caffeine might have some lasting effects on the brain.

With global life expectancy increasing, there has been growing concern about age related cognitive decline and dementia. A new study, funded by the National Institutes of Health and published in the Journal of the American Medical Association (JAMA) says that drinking two to three cups of caffeinated coffee every day is associated with a lower risk for dementia.

What the Study Found

The study, a large one that looked at thousands of adults over many years, recorded the diets and cognitive health of participants. The scientists noted that people who drank moderate amounts of caffeine a day had about a 65% reduction in developing dementia compared with those who did not or rarely consumed caffeinated beverages.

Most importantly, the protective benefit seemed more pronounced in those who had sustained moderate use—versus heavy drinking.

What Coffee Can Do for the Brain

Caffeine acts as a stimulant of the central nervous system by inhibiting adenosine receptors which are involved in promoting relaxation and sleepiness. But maybe it has benefits past staying up on a temporal basis.

Studies suggest caffeine may

• Enhance blood circulation to the brain
• Reduce inflammation
• Lower oxidative stress
• Support healthy neuronal signalling

Coffee also has antioxidants and other bioactive components that may offer protective effects on brain cells from age-related damage.

Dr. Neeraj Sharma, Sr consultant Neurologist NeuroCare, Noida explains, “Moderate caffeine consumption we speculate can act to protect the brain especially if it’s done in conjunction with other healthy lifestyle choices such as a good diet and regular exercise.”

How Much Is Considered Safe?

Moderation is key. Instead, the research indicates that drinking two to three cups of caffeinated coffee a day — or up to 400 milligrams of the stimulant, from any source – will not do people overall harm.

There are health authorities that most of the people should consume no more than about 400 milligrams of caffeine a day, or around four to five standard cups of brewed coffee. Sensitivity differs according to age, metabolism, pregnancy and general health status.

Too much caffeine, on the other hand, can cause anxiety, insomnia, palpitations or increased blood pressure — all of which are not conducive to good health.

Not a Cure, But a Preventive Habit

The results are promising, but the Doctor says coffee is not a panacea against dementia. Many factors affect cognitive health such as genetics, heart health, mental activity and social contacts.
