Ten Ways to Improve Your Memory

Brain Pictures

When your reminders affect your sense of fashion, it's time for some tips on improving memory. See more brain pictures.

­­The human brai­n is like a library that stock­s memories instead of books. In some ways, that makes the hippocampus, the part of the brain most involved in memory, the brain's librarian. The hippocampus has the most responsibility in this cranial library, juggling the new releases of short-term memory while cataloging materials for the permanent collection of long-term memory. It's not the only part at work, however, in storing these chapters of our lives. Different kinds of memory are stored in different areas of the brain. With such a large system, the brain needs a system of encoding and retrieving memories, something a bit more complex than the local library's Dewey Decimal System.


The brain has to be able to pull information at the drop of a hat, whether it's a fact on hold (such as a telephone number) or a dusty memory that's been sitting in storage for years (the memory of your first kiss). No one likes a library that loses books or shelves them in the wrong place. Yet sometimes we find ourselves with a very poor librarian on our hands, one that doesn't allow us to retrieve memories when we need them. Sometimes it's trivial, like when we tear apart our homes looking for glasses perched innocuously atop our heads, and sometimes these lapses in memories are more embarrassing, such as when we call a colleague "sport" because we simply can't remember his name.

Whether you're a college student studying for an important test or an aging baby boomer concerned about forgetting a recent doctor's appointment, there are a few things everyone can do to optimize the storage and checkouts in our private libraries of memories. Alert the librarian and head to the next page for the first tip.

10. Drink in Moderation

Before you settle in to read this article, you may want to get yourself a glass of wine. Surprised that such debauchery begins our list of memory improvers? Well, hear us out. Memory and alcohol have an interesting relationship.

Cheers to your health!First off, you'll notice we didn't advocate bringing the entire bottle back with you. Too much drinking handicaps the memory, as anyone who's ever woken after a binge with a fuzzy recollection of the night before can attest. And one component of a DUI test shows how overconsumption of alcohol can immediately affect the brain: Even simple mental tasks like counting backward and reciting the alphabet can become tricky under the influence. Alcohol abuse will have a negative effect on the cells of the brain related to memory.

But as long as you're not pregnant and able to maintain control of how much you drink, there's evidence that light to moderate alcohol consumption can improve memory and cognition. Though more research needs to be done, some studies have found that moderate drinkers do better on certain tests of memory and cognition than nondrinkers and heavy drinkers [sources: Victoroff, Minerd]. There may be some long-term effects as well. A French study that followed almost 4,000 people over the age of 65 found that light drinkers, who consumed up to two glasses of wine a day, were 45 percent less likely to develop Alzheimer's disease than nondrinkers [source: Victoroff].

But as we said, don't start tipping back beverages if you have certain risk factors, such as a family history of alcoholism. No one is recommending that teetotalers start drinking, either. Resveratrol, one of the flavonoids in red wine that's believed to have special benefits for blood vessels, is also in red grape juice.

9. Seek Treatment for Depression

Anything that causes major stress in life, including anxiety or anger, will eventually eat away at the parts of the brain that are responsible for memory. Chief among these stressors is major depression. Depression is often misidentified as a memory problem since one of the main symptoms of the condition is an inability to concentrate. If you can't concentrate on schoolwork or the information needed to complete a task on the job, then you may feel as if you're constantly forgetting things. As it is, you're not even able to concentrate long enough to learn them in the first place.

Can't concentrate at work? It may be depression.

Depression causes an increase of cortisol levels in the bloodstream, which in turns elevates the amount of cortisol in the brain. With the help of brain imaging devices, doctors have been able to see how that increased cortisol diminishes certain brain areas, chief among them the hippocampus [source: Tan]. One study showed that people who had been depressed, even if it was years ago, had suffered a 12 to 15 percent loss in the hippocampus [source: Victoroff]. Since the hippocampus is the clearing center for short-term memory, prolonged depression demolishes the brain's ability to remember anything new.

Additionally, depression affects the types of things a person is able to remember. While everyone's brain is selective about which memories make it into long-term storage, people with depression seem only able to retain negative memories [source: Crook]. That means there's a neurological reason why a person with depression remains obsessed with the one time a loved one forgot a birthday or anniversary, even if it was remembered every other year.

But happy memories needn't be lost forever to someone battling depression. Medications for depression, including selective serotonin reuptake inhibitors (SSRIs), have been shown to jump-start the process of cell regeneration in the hippocampus [source: Tan].

8. Get Moving

A brisk walk can be the best exercise for your brain.If you've ever taken a break from work or studying to take a quick walk around the block, you may understand the rationale for this next tip. Exercise not only exercises the body, it exercises the brain as well.

Obesity is a risk factor for many diseases and conditions that eventually wreak havoc on the brain, including stroke and Alzheimer's disease. Without regular exercise, plaque builds up in the arteries and blood vessels lose the ability to pump blood effectively. While you may know how plaque buildup leads to heart attacks, you may not think about the way your brain is gasping for breath as well.

The brain depends on energy received through a constant intake of oxygen and nutrients from the bloodstream, and when those nutrients don't arrive, the brain's ability to work is compromised. So to keep the blood moving to the brain, you're going to need to get up from your chair (after you finish reading this article, of course) and get the blood pumping. It doesn't matter what you do -- a brisk walk, a swim and even a dance move or two can all provide a good mental workout. Studies show that the more physically active a person is, the greater his or her cognitive performance [source: Victoroff].

Keep a lookout on your brisk walk for interesting images -- you'll need them for the memory tip on the next page.
