Johns Hopkins Researchers Find Caffeine Enhances MemoryCaffeine and memory performance -
In one study, when participants consumed a caffeine tablet after studying a series of images, their ability to recognize the images 24 hours later was strengthened.
Caffeine also appeared to make these memories more resistant to being forgotten, compared with the placebo group. While some studies have found that caffeine may improve short-term memory, others have found no effect. The effects on long-term memory need to be investigated further.
However, the energy boost only lasts for a certain amount of time before it starts to wear off. Then you may feel you need another cup. Just make sure not to consume large amounts of caffeine in the late afternoon or evening, since it might disrupt your sleep at night If drinking coffee reduces the quality of your sleep, then it will likely have the opposite effect — rather than reducing fatigue, it may cause you to lose sleep and impair your overall brain function.
People often use coffee to counteract fatigue and tiredness. However, when consumed late in the day, caffeine may reduce the quality of your sleep and as a result make you feel more tired.
It generally starts slowly but gets more severe over time. There is currently no known cure. However, the protective effects of coffee and caffeine have not been confirmed by randomized controlled trials. However, higher-quality studies are needed to confirm these findings.
There is no known cure for this condition, which makes prevention particularly important. The caffeine in coffee appears to be the active ingredient responsible for these protective effects 30 , This effect is attributed to the caffeine. In the short-term, it may improve mood, vigilance, learning, and reaction time.
However, moderation is key. When consumed in excess, caffeine can cause anxiety, jitters, heart palpitations, and sleep problems Some people are sensitive to caffeine, while others can drink many cups per day without any side effects.
That said, some people definitely need to limit their caffeine intake, including children, adolescents, and pregnant people 34 , Read this article in Spanish. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.

How does coffee affect the brain? How caffeine can boost brain function. Caffeine and memory. Whether it's a mug full of fresh-brewed coffee, a cup of hot tea, or a can of soda, consuming caffeine is the energy boost of choice for millions who want to wake up or stay up.
Now, researchers at Johns Hopkins University have found another use for the popular stimulant: memory enhancer. Michael Yassa, an assistant professor of psychological and brain sciences at Johns Hopkins, and his team of scientists found that caffeine has a positive effect on our long-term memory.
Their research, published by the journal Nature Neuroscience , shows that caffeine enhances certain memories at least up to 24 hours after it is consumed. The Johns Hopkins researchers conducted a double-blind trial in which participants who did not regularly eat or drink caffeinated products received either a placebo or a milligram caffeine tablet five minutes after studying a series of images.
Salivary samples were taken from the participants before they took the tablets to measure their caffeine levels. Samples were taken again one, three, and 24 hours afterwards. The next day, both groups were tested on their ability to recognize images from the previous day's study session.
On the test, some of the visuals were the same as those from the day before, some were new additions, and some were similar but not the same.
More members of the caffeine group were able to correctly identify the new images as "similar" to previously viewed images rather than erroneously citing them as the same. The brain's ability to recognize the difference between two similar but not identical items, called pattern separation, reflects a deeper level of memory retention, the researchers said.
The memory center in the human brain is the hippocampus, a seahorse-shaped area in the medial temporal lobe of the brain. The hippocampus is the switchbox for all short- and long-term memories.
Most research done on memory—the effects of concussions in athletes, of war-related head injuries, and of dementia in the aging population—focuses on this area of the brain. Until now, caffeine's effects on long-term memory had not been examined in detail.
Of the few studies done, the general consensus was that caffeine has little or no effect on long-term memory retention. The research is different from prior experiments because the subjects took the caffeine tablets only after they had viewed and attempted to memorize the images.
According to the U. Food and Drug Administration, 90 percent of people worldwide consume caffeine in one form or another. In the United States, 80 percent of adults consume caffeine every day. The average adult has an intake of about milligrams—the same amount used in the Yassa study—or roughly one cup of strong coffee per day.
Yassa's team completed the research at Johns Hopkins before his lab moved to the University of California, Irvine, at the start of this year.
We also know that caffeine is associated with healthy longevity and may have some protective effects from cognitive decline like Alzheimer's disease.

There has been some encouraging research regarding the use of caffeine in older adults to counteract the natural declines in memory that are associated with age. For example, one study showed that caffeine reduced the afternoon decline in memory experienced by "morning people"—older adults who generally perform better in the morning than in the afternoon.
However, other research indicates that caffeine is not a reliable way of improving memory in older people. In fact, research has shown that older people perform more poorly on tests of episodic memory after consuming caffeine-containing foods than those who do not.
And although there is evidence that habitual caffeine use is associated with a modest advantage in long-term memory, this does not counter age-related memory declines. As caffeine is an addictive substance, trying to self-medicate what you believe to be a poor memory may actually be making matters worse.
For example, caffeine tends to interfere with your sleep and is followed by a withdrawal period, both of which can cause memory problems. Talk to your doctor to find out whether you really have problems with your memory, other ways of improving your memory, and what an optimal amount of caffeine would be for you.

| Does Caffeine Consumption Actually Improve Memory? | This stimulant blocks adenosine, an inhibitory neurotransmitter in the brain that makes you sleepy. Brain entropy is vital to brain function, and high levels point to high processing abilities. An increase in resting brain entropy suggests higher information-processing capacity 7. Caffeine also stimulates the CNS by promoting the release of other neurotransmitters, including noradrenaline, dopamine, and serotonin 8. Caffeine may improve various aspects of brain function, including 9 :. That said, you may develop a tolerance to caffeine over time. This means you will need to consume more coffee than before to get the same effects. In fact, the Food and Drug Administration FDA has stated that healthy adults should only consume about 4 or 5 cups milligrams daily to avoid potentially dangerous or adverse side effects. And if you are trying to become pregnant or are pregnant, breastfeeding, sensitive to caffeine, taking medications, or living with an underlying condition, you may want to speak with a healthcare professional. Together you can decide what amount of caffeine is appropriate for you Caffeine causes changes in several neurotransmitters that may improve mood, reaction time, learning, and vigilance.

Having an alcoholic drink a day might also benefit our mental performance, but the line between just right and too much is uncertain. An even better strategy for maintaining memory and thinking skills with age may be to eat a healthy diet. In the study, researchers from the National Institute on Aging compared scores on various tests of thinking skills and memory with caffeine, alcohol, and nutrient intake in men and women taking part in the Baltimore Longitudinal Study of Aging. Over all, participants who ranked high on the healthy diet scale did better on 10 tests of memory than those with lower diet scores. The same held true for those who took in more caffeine. The effects for moderate alcohol drinking were mixed. The reason you get a quick wakeup call after chugging a mug of coffee has to do with the way caffeine tricks your brain. Not only is caffeine a brain stimulant, but it also blocks receptors for a chemical called adenosine, which normally prevents the release of excitatory brain chemicals. With adenosine out of the way, these brain-sparking chemicals can flow more freely—giving you a surge of energy and potentially improving mental performance and slowing age-related mental decline. It showed that people—particularly those who were ages 70 and over—who took in more caffeine scored better on tests of mental function, but not on memory tests or other measures of mental ability. In this study, moderate alcohol use appeared to improve working memory and attention—especially in women and in those ages 70 and over. But those benefits could come at the expense of declines in skills like executive function and global thinking. Excessive drinking, defined as more than two drinks a day for men or more than one a day for women, is known to harm the brain. Over time, excessive drinking can cause everything from short-term memory lapses to more permanent problems. Any benefits from alcohol seen in the Journal of Nutrition study came from moderate drinking. The study also looked at the connection between diet and mental performance. People who ate foods with plenty of healthful nutrients had better attention and memory than participant with poorer diets. A healthy diet was also linked to good thinking skills in women and participants under age This study is just one of many linking healthy eating habits with maintaining memory and thinking skills into old age. Continuing a healthy diet, or switching to one, makes sense on many levels. As for caffeine? If you like drinking caffeinated beverages, enjoy them. But keep in mind that adding lots of sugar or cream, or getting caffeine via sugar-sweetened soda, may counter any benefits. What about alcohol? If you enjoy drinking alcohol, keep it moderate—or less. Stephanie Watson , Former Executive Editor, Harvard Women's Health Watch.
