Tricks to Improve Your Memory

Technique # 1: Play brain games

Puzzles like Sudoku and crosswords may improve memory and delay brain decline, though experts are not yet sure why. "My guess is that playing them activates synapses in the whole brain, including the memory areas," says Marcel Danesi, PhD, author of Extreme Brain Workout. Research so far is decidedly mixed: Some studies have found that, while doing crossword puzzles may make you better at remembering the capital of Burkina Faso, there's little evidence they'll boost your performance at more general tasks, like remembering where your car is parked . But a 2011 study showed that participants who played a computer game called Double Decision for six years improved their concentration so much that they had a 50 percent lower rate of car accidents.

So I decided to try an online brain-training program called Lumosity, which neuroscientists from Harvard, Stanford and the University of California at Berkeley have used in their own studies; its creators claim that 97 percent of users improve their memory in just 10 hours of playing time. First I answered a series of questions at lumosity.com to identify which of my cognitive processes, including memory, could use a little help. Then I received a personalized training regimen. A 10-minute daily series of games is free, and a more advanced program is available for $ 12.95 a month. (Being cheap, I stuck with the former.) The games are pure fun-remembering a pattern of blocks, spotting a bird in a field-and are based on what research has found to improve concentration and other cognitive skills.

My grade: B- By the end of a month, my "brain performance index" score rose 6 percent-not amazing in the Lumosity world, but respectable. The main problem: You have to play the games every day, forever, to keep up the benefits. I've mostly kept up. (Except on weekends. Or if I've had a busy week. OK, I have not kept up.)

Technique # 2: Eat the right foods

According to Gary Small, MD, director of the UCLA Memory Clinic, memory superfoods include antioxidant-rich, colorful fruits and vegetables, which protect your brain from harmful free radicals. He's also enthusiastic about low-glycemic carbs, like oatmeal, and anything with omega-3 fatty acids. In fact, a recent study published in Neurology found that people with low levels of omega-3s had brains that appeared to be a full two years older in MRI scans. That was incentive enough for me to follow the memory-enhancing diet from Dr. Small's book The Memory Prescription, which claims it works in just two weeks. Much like the Mediterranean diet, it's heavy on produce, legumes, nuts and fish. It's low on meat, since meat's omega-6 fatty acids may contribute to brain inflammation, a possible underlying mechanism for Alzheimer's. Refined sugars produce a similar effect, so they were also out. (That was the toughest for me.) I ate a farmers market's worth of blueberries, spinach, avocado and beets, and consumed enough fish to sprout gills. I also went beyond Dr. Small's advice and took 2.4 micrograms of vitamin B12, the standard recommended daily amount-since studies show people with low levels perform poorly on memory tests-and 1,000 international units of vitamin D, discovered by Tufts University researchers to boost cognitive function. (My doctor signed off on 

the supplements.)

Stop Multitasking

Used for decades to describe the parallel processing abilities of computers, multitasking is now shorthand for the human attempt to do simultaneously as many things as possible, as quickly as possible. Ultimately, multitasking may actually slow you down, make you prone to errors as well as make you forgetful.

Research shows you actually need about eight seconds to commit a piece of information to your memory, so if you're talking on your phone and carrying in groceries when you put down your car keys, you're unlikely to remember where you left them.

The opposite of multitasking would be mindfulness, which helps you achieve undistracted focus. Students who took a mindfulness class improved reading comprehension test scores and working memory capacity, as well as experienced fewer distracting thoughts.2

If you find yourself trying to complete five tasks at once, stop yourself and focus your attention back to the task at hand. If distracting thoughts enter your head, remind yourself that these are only "projections," not reality, and allow them to pass by without stressing you out. You can then end your day with a 10- or 15-minute meditation 

session to help stop your mind from wandering and relax into a restful sleep.

Master a New Skill

Engaging in "purposeful and meaningful activities" stimulates your neurological system, counters the effects of stress-related diseases, reduces the risk of dementia and enhances health and well-being.6 A key factor necessary for improving your brain function or reversing functional decline is theseriousness of purpose with which you engage in a task. In other words, the task must be important to you, or somehow meaningful or interesting — it must hold your attention.

For instance, one study revealed that craft activities such as quilting and knitting were associated with decreased odds of having mild cognitive impairment. Another study, published earlier this year, found that taking part in "cognitively demanding" activities like learning to quilt or take digital photography enhanced memory function in older adults. The key is to find an activity that is mentally stimulating for you. Ideally this should be something that requires your undivided attention and gives you great satisfaction… it should be an activity that you look forward to doing, such as playing a musical instrument, gardening, building model ships, crafting or many others.
